N2O emissions from humid tropical agricultural soils: effects of soil moisture, texture and nitrogen availability. Let's review. Detritivores are organisms that get their needed energy and nutrients by eating dead organic matter, such as dead plants, dead animals, and fecal matter. This dead organic matter is called detritus. & Triplett, E. W. Molecular microbial diversity in soils from eastern Amazonia: evidence for unusual microorganisms and microbial population shifts associated with deforestation. Detritivores are scavengers and are called Tertiary Consumers, theyll eat any left over food, dead or alive, and theyll even eat other animal or plants wastes.Any left over bone or meat then decomposes and fertilises the ground which then helps other plants grow.Energy that travel through the food chain is inefficient, this meaning that the less energy or sunlight that gets through to the plants, then less energy for the herbivores to consume, than less for the carnivores and omnivores, making it harder for the Detritivores to stay alive and other mentioned.WHERE TROPICAL RAINFORESTS ARE FOUND:Tropical rainforests are found in a band around the equator. 15, 15841597 (2009).
