Abiotic factors

The abiotic factors of this rainforest biome are-the amount of water and sunlight, climate, weather and precipitation. these things affect the trees and animals that live there. These are very important because without the right amount of water and sunlight the trees in the rainforest would not be able to grow and would die. These factors also affect the types of plants and animals that can live in this area. A good example is that a lot of small bushes and shrubs would not be able to live here because all the really tall trees would block most of the sunlight causing a lack in sunlight to the bushes and shrubs below them. This will cause the bushes and shrubs to die.

The tropical rainforest biome has a very warm and wet climate. It has an average temperature of 20-34 degrees Celsius . Because this biome is located very close to the equator, it  has very little seasonal change in temperature or the length of a day. In this location, it has more direct sunlight hitting land and sea than most other areas. This makes it very good for the growth of plants. The sun warms the land and sea and the water evaporates into the air. The warm air can hold a lot of water vapor. As this warm air rises to meet the cooler air above the earth's surface, condensation takes place as the air is cooled down. From this condensation, clouds are formed that eventually produce rain.  The tropical rainforest biome has a annual rainfall of more than 250 centimeters and has average humidity between 77 and 88%. It rains more than ninety days a year in the rainforest, and between these rain storms, the warm sun usually heats up the earth. The warm air and lots of rain make it a perfect climate for growing most trees, and they can grow extremely large and tall in the rainforest. Some trees grow to the height of more than 165 feet and have straight trunks that don't branch out for 100 feet or more. The  tall trees branches can form a canopy or shield preventing the rain and sun from reaching the ground or the under story which is the floor of the forest. There is little light below the canopy so most trees do not have branches or leaves below this level.  The plants the grow below the canopy, such as mosses and ferns adapt to the lack of sunlight and can grow quite well along the floor of the forest. About one quarter of all the medicines we use today come from  the rainforest plants and many varieties of tropical plants are believed to be potential cures for cancer. Most of the rainforest's animals live in the upper canopy, between the layers of branches on the trees. There is so much food available at this level that some animals never go down to the forest floor.
