A tropical rainforest is a humid, moist biome located near the Earth’s equator, with the world’s largest rainforest being in South America, Southeast Asia and Africa. Rainforests collect from 60 to 160 inches of rainfall throughout the year, with the constant humidity and moisture within the rainforest creates the perfect biome for tropical condition thriving plants and animals. One of the world’s best environments for biodiversity are the tropical rainforests, they contain 15 million species of plants and animals. The humid conditions of the tropical rainforests are ideal for bacteria and other microorganisms, these organisms remain active for the whole year being at ...view middle of the document...
Because there are so many animals competing for food, many animals have adapted by learning to eat foods not eaten by other animals. Toucans and sloths for example have both adapted within the rainforest. The toucan developed a long, large bill allowing the toucan to reach fruit on branches too small to support the birds’ weight, also the toucan uses it bill to cut the fruit from trees.
The sloth uses behavioural and camouflage adaptions. It moves very slowly and spends most of its time hanging upside down from trees. Algae grow on the fur of the sloth giving it a greenish color and making it harder for predators to spot.
Rainforests receive around 12 hours of sunlight per day only 2% of the sunlight makes it through the dense vegetation and into the soil. The tropical rainforest is made up of three different layers, the canopy, the understory and the ground layer. Very little vegetation is able to survive on the ground layer because the canopy created by tall trees of 100 to 120 feet tall and the understory don’t allow much light to get through. The most amount of living vegetation is found closest to or surrounding riverbanks this is because the trees are parted around the river bank allowing more light from the sun to shine through and give the energy needed for the plan to survive.
Plant survival within the tropical rainforest depends on the plants ability to tolerate constant shade or adapt strategy’s to reach sunlight. Fungus is the perfect example of a plant that survives inside the ground layer exceling growth in warm, dark places. The competition for sunlight is sometimes deadly for example the strangler fig will die without sunlight to reproduce and grow. When its seeds fall to the ground they almost instantly die hitting the acidic soil without sunlight, so it has adapted by depositing its seeds on high branches transported by birds and other animals that have eaten the fruit off the strangler fig. the seeds then sprout and send a long root to the ground layer, rapidly increasing the diameter and successfully competes for water and nutrients in the soil. As the strangler fig grows, branches and leaves will grow upwards eventually creating a canopy that will block the sunlight from the tree in which the seed grew from, other roots from the strangler fig tree will reach around the ‘host’ tree, strangle it and eventually kill the tree in order for the strangler fig to survive.
Deciduous forests are located between the Polar Regions and the tropic regions. They are located here because of the air masses from both the cold polar region and warm tropical region allow the climate to have a refreshing variety inside this biome. Deciduous forests have both warm and cold seasons, rainfall can range from 30 to 60 inches that is usually evenly distributed over the year, the word...
