Primary and Secondary Succession

Primary Succession:
In tropical rainforest, flooding happens quite often from the profuse rain. This strips the topsoil, so the environment must create new. 

Secondary Succession:
Farmers in the rainforest cut down large areas of trees to grow their crops and after a few years the soil becomes infertile. After the farmer moves, secondary succession sets in, fertilizing the soil and growing small plants and trees again until the forest, after hundreds of years, has grown back.
