Rain forests recycle nutrients. (Apex)

Explanation:

Plants can convert atmospheric carbon dioxide to other carbon based compounds through photosynthesis. Rain forests are the largest carbon revisers and are responsible for most of the oxygen in the atmosphere  

Basically they take in carbon dioxide,convert it to oxygen and then release the oxygen back into the environment. Thus helping to prevent the plant from heating up.

Their productive organisms quickly recycle nutrients.
