The fertility of soil in tropical rainforests is maintained by the abundant supply of litter. The rainforest has a high level of biodiversity, and the decomposition of dead organic matter and the recycling of nutrients is critical to the ecosystem's health. The hot and wet climate of the rainforest allows for rapid decay of dead plant and animal material, creating a layer of organic matter on the forest floor called litter. This litter is rich in nutrients and is quickly absorbed by the roots of the vegetation, replenishing the soil with essential nutrients. As a result, the soil in tropical rainforests is incredibly fertile, making it an ideal environment for a diverse range of flora and fauna to thrive.
