Rainforest-abiotic factors

Hi, I am working on a school project. What you have to do is find an ecosystem of your choice and research on it. There is one tab that is listed as "Working Together" which states that you have to list the biotic and abiotic factors that work together in the environment. I can't seem to find it no matter how hard I try. I have chosen the Amazon rainforest and no matter where I look i can't seem to find anything. Does anyone know anything about this?

I need to do some research for a project. Cited sources would be appreciated :) I tried are answers and I got nothing so biology is the next best thing as this project is on biomes
