Tropical Rainforest

Adaptations for Animals

-Learning to eat a particular food not eaten by many other animals. An Example is Toucans that developed long, large bills. These allow the birds to reach fruits on branches that are too small to support the bird's weight. Their bill is also used to cut the fruit from the tree.


-Camouflage. For example, the sloth moves very slowly, causing blue-green algae to grow on it's fur, giving the sloth a greenish look to help it blend in.


-Living on a particular area to avoid competition for food and predators. An example is Spider monkeys that live in the upper canopy (tree top canopy) to avoid predators and experience little competition for food (the spider monkey's tail gives it the ability to swing from tree to tree, allowing it to live in the tree top canopy)

Adaptations for Plants

-Drip Tip. Due to high amounts of rain fall, the drip tip enables rain drops to run off quickly. The reason that these are so essential is due to the fact that plants need to shed water quickly to avoid growth of fungus and bacteria in warm, wet climate. (Forest Trees as an example)


-Plants adapting to reach sunlight. As example, Liana plants. Lianas are woody climbing vines that drape rainforest trees. They keep their roots in the ground and climb high into the tree canopy to reach available sunlight. Most start in the rainforest canopy and send roots down to the ground.


-Widespread stilt roots. An example being the Mangrove tree. The Mangroves, as well as other trees have adapted to living in the wet marshy areas (such as tropical deltas) by having wide-spreading stilt roots that support the tree in the mud and trap nutritious organic matter.

Interesting Facts

The trees of tropical rain forests are so densely packed that rain falling on the canopy can take as long as 10 minutes to reach the ground.
Bats are essential for the pollination of many tropical foodstuffs such as bananas and mangos.
Rain forests only cover 2% of the total surface area of Earth, but 50% of the plants and animals on earth live in the rainforest.
A fifth of our fresh water is found in tropical rain forests, the Amazon Basin to be exact.

Habitats

Trees are great habitats but to be more specific the Durian and Kapok tree are both very tall and can support various creatures living in the tropical rain forest. Birds really like tall trees because it keeps them safe and also their eggs. There is also various types of fruits that they use as a food source.


Amazon, Madeira, Mekong, Negro, and Congo are all lakes found in the tropical rain forest. They all support life for animals like fish, Newts, tadpoles, Earthworms, leeches, Snapping turtles, ducks, etc. These lake like areas all have a food chain within its self, where plants and animals all depend on each other to survive.


The Forest Floor is were less than 1% of the light strikes. The top of the soil is very thin and poor quality. A lot of litter falls to the ground where it is broken down by decomposes like termites, earthworms, and fungi.


The Understory is made up of shrubs, plants and small trees. Animals like spiders, bees, snakes, frogs, and jaguars live here. Plants like tree trunks, saplings, small ground plants, and vines all help the life of these animals.

Limiting Factors

Sunlight in the tropical rain forest is a limiting factor because sunlight manly hits only the first layer of the rain forest. Meaning some plants don't get the right amount of sunlight causing them to die off. Soil in the tropical rain forest is a limiting factor because it is not filled with too many nutrients, and because of this, plants sometimes don't get enough of it.

Abiotic and Biotic Factors

The abiotic (non-living) factors in the tropical rainforest include but does not limit to water, rocks, sunlight and soil. Some of the biotic (living) factors are the jaguar, avocodo, rubber tree, and capuchu monkey.

Mutualistic relationship

The capuchin monkey and a flowering avocado tree, the monkey feeds on the flowers necter, the flower's pollen gets on the monkey's face. The pollen then gets transfered when the monkey goes and eats from another flower.

Commensalistic and parasitic relationship

New world army ants and the antbirds, the ants march causing bugs to fly into the air and then the antbirds eat them.

The phorid flies and the leaf cutter ants, the ants go and collect the leaves, the flies attack the ants and lay eggs int the ants head, when the eggs hatch the baby can get all the nutrients from the ant.
