Rotting carcass is a biotic factor.

Biotic factors are the existing components of an ecosystem. Because of the way ecosystems work as complicated systems of rivalry and collaboration, where the action of each life structure can affect all the others any alive being within an ecosystem can be thought a biotic factor. Biotic factors so as clay bacteria, plant growth, prime predators, and polluters can all extremely shape which organisms can exist in ecosystems and what endurance strategies all practice. Biotic factors, collectively with non-living abiotic factors such as temperature, daylight, geology, and chemistry, circumscribe what ecosystems look similar and what environmental crannies are possible.
