Where are the Rainforests?
The Rainforest you usually think of, the tropical rainforest, are found usually between 30ºN and 30ºS in latitudes. They can be found in Central and South America, Western Africa, Eastern Madagascar, Zaire Basin, Indo-Malaysia along the west coast of India, Assam, Southeast Asia, New Guinea, and Queensland, Australia.
What is the Weather Like?
The tropical rainforest gets a lot of rain and they help to maintain global weather patterns and rain, because the water that evaporates from the top of trees and becomes rain in other areas. The rainforest is always warm and filled with colors with temperature of about 75-80ºF year round. The environment is also wet year round with a constant humidity of 77-88%. The rainforest gets about 80-400 inches of rain per year, and can the rain can fall at a rate of up to 2 inches per hour.
Different Animals in the Rainforest
New World Monkey
This is the New world monkey and it can curl its tail so it can be secure on the tree.
These are the types of plants that climb up trees to get to the sunlight.
Poison Dart Frogs
Poison dart frogs can shoot venom at their enemies and can be very deadly.
Plant and Animal Interdependency
In the rainforest many organisms have to depend on each other. Many animals rely on another for their food while others rely on the plants and trees for their home. Many animals have become adapted to living in the trees and never come down to the ground. One example is the birds pick up seeds of the forest floor and accidentally drop some which grow more plants and supply more food.
Plant and Animal Variations
In the tropical rainforest, you can find many different animal and plant species. You can find many different types of epiphytes and more than 20,000 different kinds of orchids, and tropical rainforests are also home to half the plant and animal species on earth. Some scientists believe this diversity is because the rainforests are one of the oldest ecosystems on earth.
Plant and Animal Adaptations
There are many different adaptations that have helped in keeping a species alive. One good example for plants is the Epiphytes. Since the rainforest is so thick, it is hard to get sunlight if your at the bottom. These plants grow on trees to get the sunlight they would have not gotten if they were underneath the canopy. Most trees are adapting to the Epiphytes by having thin, smooth bark. Smooth bark makes it harder for plants like Epiphytes to grown on the tree. They also have large buttresses for support because their roots are shallow. Many plants in general have adapted leaf shapes so that water can drip off the plant so there won't be too much moisture which would cause bacteria and fungus growth. Another plant, a vine called Lianas, also climb trees to the canopy layer to get sunlight. There are also different adaptations among the animals in the Rainforest. A very common one is that they live in trees. Another example is the New World monkeys. Their tails are able to curl and hold on to branches. The Rainforest biome has many examples of adaptations.
Did you Know?
Rainforests cover 6-7% of the Earth's land surface
Some forests in Southeast Asia have been around for 100 million years
Adding an Exotic Species
Adding the penguin would not really change anything because the penguin is used to eating fish and would not be able to find any so it would starve and get eaten because Quaternary consumers are used to eating birds and the penguin would just be an easy to spot out prey.
Taking away a species
Taking away the Brazil nut tree will take away everything because the primary consumers won't get food and will starve and then the other consumers would starve as a result.
