What Are The Abiotic Factors Of The Tropical Rain Forests?

A tropical rain forest is a region of trees in year round warmth.


It gets an average of 50-260 inches of rainfall year round.

They belong to a Tropical Wet Climate group.

The temperature in the Rain Forest rarely gets above 93 degrees and rarely gets lower than 68 degrees.

The average humidity is between 77% and 88%.

Rain Forests cover less than 6% of the worlds surface and scientists estimate that about 40% of the worlds oxygen comes from tropical rain forests.

There aren't really any season changes in tropical rain forests because they pretty much stay about the same temperature all year round.


Competition in the tropical rain forests

There is a lot of predator/pray relationships in the rain forests such as the anaconda and the capybara, fruit bats and insects, and boa constrictors and small rodents.

There are also a number of intraspecific competitions in tropical rain forests as well such as two fruit bats competing over the same insects or two snakes competing for the same rodent.

Fun Facts

  • Bamboo plants found in rain forests can grow up to 9 inches a day.
  • The trees are so dense that rain can take up to ten minutes to reach the ground.
  • More than 2,000 types of butterflies are found in the South American rain forests
