Legume abundance along successional and rainfall gradients in Neotropical forests. WebWolves in the food chains are found as apex predators that serve to maintain equilibrium in their ecosystems by mostly consuming elderly, ill, or weak prey.

Soil Use Manag. 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.

Melissa Petruzzello is Associate Editor of Plant and Environmental Science and covers a range of content from plants, algae, and fungi, to renewable energy and environmental engineering. Did Billy Graham speak to Marilyn Monroe about Jesus? For this reason, rainforest trees and other plants that have been cut down are rarely able to grow back, as there are simply not enough nutrients in the soil for the vegetation to regenerate. van Straaten, O. et al.
