Digestion is the complex process of turning the food you eat into nutrients, which the body uses for energy, growth and cell repair needed to survive. The digestive tract (or gastrointestinal tract) is a long twisting tube that starts at the mouth and ends at the anus. The mouth is the beginning of the digestive system, and, in fact, digestion starts here before you even take the first bite of a meal.
Once you start chewing and breaking the food down into pieces small enough to be digested, other mechanisms come into play. Also called the throat, the pharynx is the portion of the digestive tract that receives the food from your mouth. Tropical forests presently cover about 2.4 billion hectares or about 16 percent of Earth's land surface. Rainforests also exist outside the tropics, including temperate North America, South America, Australia, and Russia.
Rainforests are forest ecosystems characterized by high levels of rainfall, an enclosed canopy and high species diversity. Tropical rainforests typically occur in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn, latitudes that have warm temperatures and relatively constant year-round sunlight. Rainforests provide important ecological services, including storing hundreds of billions of tons of carbon, buffering against flood and drought, stabilizing soils, influencing rainfall patterns, and providing a home to wildlife and indigenous people. While rainforests are critically important to humanity, they are rapidly being destroyed by human activities. The rainforest section of Mongabay is divided into ten "chapters" (the original text for the site was a book, but has since been adapted for the web), with add-on content in the form of special focal sections (e.g.
Each rainforest is unique, but there are certain features common to all tropical rainforests. Canopy: rainforests have a canopy, which is the layer of branches and leaves formed by closely spaced rainforest trees some 30 meters (100 feet) off the ground. Biodiversity: rainforests have extraordinarily highs level of biological diversity or a€?biodiversitya€?.
Other countries that have large areas of rainforest include Bolivia, Cameroon, Central African Republic, Ecuador, Gabon, Guyana, India, Laos, Malaysia, Mexico, Myanmar, Papua New Guinea, Republic of Congo, Suriname, and Venezuela. Rainforests are characterized by a unique vegetative structure consisting of several vertical layers including the overstory, canopy, understory, shrub layer, and ground level. Climate: because rainforests are located in tropical regions, they receive a lot of sunlight. Canopy: the canopy structure of the rainforest provides an abundance of places for plants to grow and animals to live. Competition: while there is lots of energy in the rainforest system, life is not easy for most species that inhabit the biome. While species everywhere are known for utilizing symbiotic relationships with other species to survive, the biological phenomenon is particularly abundant in rainforests. In the rainforest most plant and animal life is not found on the forest floor, but in the leafy world known as the canopy.
The conditions of the canopy are markedly different from the conditions of the forest floor. Scientists have long been interested in studying the canopy, but the height of trees made research difficult until recently.
The rainforest floor is often dark and humid due to constant shade from the leaves of canopy trees.
Despite its constant shade, the ground floor of the rainforest is the site for important interactions and complex relationships. Tropical rainforests support some of the largest rivers in the world, like the Amazon, Mekong, Negro, Orinoco, and Congo.
Rainforest waters are home to a wealth of wildlife that is nearly as diverse as the biota on land. Tropical rainforests have long been home to tribal peoples who rely on their surroundings for food, shelter, and medicines.
Of the remaining forest people, the Amazon supports the largest number of indigenous people living in traditional ways, although these people, too, have been impacted by the modern world.
Every year an area of rainforest the size of New Jersey is cut down and destroyed, mostly the result of human activities. Rainforests are also threatened by climate change, which is contributing to droughts in parts of the Amazon and Southeast Asia. While rainforests may seem like a distant concern, they are critically important for our well-being. Help stabilize the worlda€™s climate: Rainforests help stabilize the worlda€™s climate by absorbing carbon dioxide from the atmosphere.


Provide a home to many plants and animals: Rainforests are home to a large number of the worlda€™s plant and animals species, including many endangered species.
Help maintain the water cycle: The role of rainforests in the water cycle is to add water to the atmosphere through the process of transpiration (in which plants release water from their leaves during photosynthesis). Protect against flood, drought, and erosion: Rainforests have been compared to natural sponges, moderating flood and drought cycles by slowing run-off and contributing moisture to the local atmosphere.
Are a source for medicines and foods and support forest-dependent people: People have long used forests as a source of food, wood, medicine, and recreation. However, as frosts sweep through in the fall and winter, sometimes you're stuck picking a whole bunch of peppers all at once in order to save them from the cold. Since peppers are edible and tasty in all stages of growth, why not make yourself a big batch of hot pepper sauce? Today I'll show you how to take your smoked peppers and turn them into a hot sauce that's so savory and incredible that it would make Chuck Norris cry. Okay, now you blend the sauce a final time to mix it all in, then pour your freshly minted smoky homemade hot pepper sauce into Mason jars for canning. At this point you can either throw your hot sauce in the fridge (it will keep for a long time that way, thanks to the vinegar) or you can go ahead and can it. This sauce has a rich, smoky-hot flavor that will make you want to eat more and more of it. It is made up of a series of muscles that coordinate the movement of food and other cells that produce enzymes and hormones to aid in the breakdown of food. The smell of food triggers the salivary glands in your mouth to secrete saliva, causing your mouth to water. More saliva is produced to begin the process of breaking down food into a form your body can absorb and use. Branching off the pharynx is the esophagus, which carries food to the stomach, and the trachea or windpipe, which carries air to the lungs. While tropical rainforests are the best-known type of rainforest and the focus of this section of the web site, rainforests are actually found widely around the world, including temperate regions in Canada, the United States, and the former Soviet Union.
Tropical rainforests merge into other types of forest depending on the altitude, latitude, and various soil, flooding, and climate conditions. The Congo Basin and Southeast Asia, respectively, have the second and third largest areas of tropical rainforest. Rainforests are also the source of many useful products upon which local communities depend. Just over half the world's rainforests lie in the Neotropical realm, roughly a quarter are in Africa, and a fifth in Asia. The canopy refers to the dense ceiling of leaves and tree branches formed by closely spaced forest trees.
Although they cover less than 2 percent of Eartha€™s surface, rainforests house more than 50 percent of the plants and animals on the planet. The canopy offers sources of food, shelter, and hiding places, providing for interaction between different species. In fact, the rainforest is an intensively competitive place, with species developing incredible strategies and innovations to survive, encouraging specialization.
The canopy, which may be over 100 feet (30 m) above the ground, is made up of the overlapping branches and leaves of rainforest trees.
During the day, the canopy is drier and hotter than other parts of the forest, and the plants and animals that live there have adapted accordingly. Today the canopy is commonly accessed using climbing gear, rope bridges, ladders, and towers. The canopy not only blocks out sunlight, but dampens wind and rain, and limits shrub growth.
The forest floor is one of the principal sites of decomposition, a process paramount for the continuance of the forest as a whole. For example, more than 5,600 species of fish have been identified in the Amazon Basin alone.
Dams, deforestation, channelization and dredging, pollution, mining, and overfishing are chief dangers. Today very few forest people live in traditional ways; most have been displaced by outside settlers, have been forced to give up their lifestyles by governments, or have chosen to adopt outside customs. Nonetheless, indigenous peoples' knowledge of medicinal plants remains unmatched and they have a great understanding of the ecology of the Amazon rainforest.
Today export-driven industries are driving a bigger share of deforestation than ever before, marking a shift from previous decades, when most tropical deforestation was the product of poor farmers trying to put food on the table for their families.
Drought causes die-offs of trees and dries out leaf litter, increasing the risk of forest fires, which are often set by land developers, ranchers, plantation owners, and loggers. Rainforests are often called the lungs of the planet for their role in absorbing carbon dioxide, a greenhouse gas, and producing oxygen, upon which all animals depend for survival. Scientists have shown that excess carbon dioxide in the atmosphere from human activities is contributing to climate change.
This moisture contributes to the formation of rain clouds, which release the water back onto the rainforest.


Rainforests are also important in reducing soil erosion by anchoring the ground with their roots. Policymakers and companies are increasingly valuing rainforests for the services they afford, setting aside large blocks of forests in protected areas and setting up new financial mechanisms that compensate communities, state and local governments, and countries for conserving forests. Growing population and consumption means that rainforests will continue to face intense pressures. The actions we take in the next 20 years will determine whether rainforests, as we currently know them, are around to sustain and nourish future generations of people and wildlife. Along the way are three other organs that are needed for digestion: the liver, gallbladder, and the pancreas. These forest types form a mosaic of vegetation types which contribute to the incredible diversity of the tropics.
Rainforests also exist on some the Caribbean islands, in Central America, in India, on scattered islands in the South Pacific, in Madagascar, in West and East Africa outside the Congo Basin, in Central America and Mexico, and in parts of South America outside the Amazon. The upper canopy is 100-130 feet above the forest floor, penetrated by scattered emergent trees, 130 feet or higher, that make up the level known as the overstory.
For example, there are plants in the canopy called bromeliads that store water in their leaves. Scientists estimate that more than half of life in the rainforest is found in the trees, making this the richest habitat for plant and animal life. For example, because the amount of leaves in the canopy can make it difficult to see more than a few feet, many canopy animals rely on loud calls or lyrical songs for communication. It provides support for trees responsible for the formation of the canopy and is also home to some of the rainforest's best-known species, including gorillas, tigers, tapirs, and elephants, among others.
For example, the Amazon alone has some 1,100 tributaries, 17 of which are over 1,000 miles long. Their small size enables them to move about the forest more efficiently than taller people. New Guinea and the Andaman Islands are generally viewed as the last frontiers for forest people in Asia and the Pacific. Rainforests also stabilize climate, house incredible amounts of plants and wildlife, and produce nourishing rainfall all around the planet.
Therefore, living rainforests have an important role in mitigating climate change, but when rainforests are chopped down and burned, the carbon stored in their wood and leaves is released into the atmosphere, contributing to climate change.
When trees are cut down there is no longer anything to protect the ground, and soils are quickly washed away with rain. The bad news is that saving rainforests will be a challenge as it means humanity will need to shift away from business-as-usual practices by developing new policies and economic measures to creative incentives for preserving forests as healthy and productive ecosystems.
Meanwhile, forest-dependent people are gaining more management control over the forests they have long stewarded. At the same time, climate change threatens to dramatically alter temperatures and precipitation patterns, potentially pushing some forests toward critical tipping points.
Rainforests describes tropical rainforests, why they are important, and what is happening to them.
Logging is the biggest cause of forest degradation and usually proceeds deforestation for agriculture. Below the canopy ceiling are multiple leaf and branch levels known collectively as the understory. Gaps between trees mean that some canopy animals fly, glide, or jump to move about in the treetops. Although large tropical rivers are fairly uniform in appearance and water composition, their tributaries vary greatly.
While companies have a greater capacity to chop down forests than small farmers, they are more sensitive to pressure from environmentalists.
When forests are cut down, less moisture goes into the atmosphere and rainfall declines, sometimes leading to drought.
Large international companies are finally establishing policies that exclude materials sourced via deforestation. Your digestive system performs amazing feats every day, whether you eat a double cheeseburger or a stalk of celery.
The lowest part of the understory, 5-20 feet (1.5-6 meters) above the floor, is known as the shrub layer, made up of shrubby plants and tree saplings.
Thus in recent years, it has become easiera€”and more ethicala€”for green groups to go after corporations than after poor farmers. Read on to learn what exactly happens to food as it makes its way through your digestive system. For example researchers have shown that forests in South America affect rainfall in the United States, while forests in Southeast Asia influence rain patterns in southeastern Europe and China.
