Consumer effects on rainforest primary production are often considered negligible because herbivores and macrodetritivores usually consume a small fraction of annual plant and litter production, even though consumers are known to have effects on plant production and composition in nontropical systems.

These forests share many animal species with neighboring rainforests and savannas, including monkeys, parrots, and large cats, and a number of animals make seasonal migrations to wetter habitats during the dry season. Well youre wrong! The rate and degree of soil degradation following deforestation are a function of the inherent soil fertility and land-use intensity. 17, 137167 (1986).

Open Access 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. A., Adams, C., Manfredini, S., Aguilar, R. & Neves, W. A. Dynamics of soil chemical properties in shifting cultivation systems in the tropics: a meta-analysis. 55, 178183 (1991).

They should be distinguished from other decomposers, such as many species of bacteria, fungi and protists, which are unable to ingest discrete lumps of matter, but instead live by absorbing and metabolizing on a molecular scale (saprotrophic nutrition).

On each research site, we collected the leaf litter on three square-meters of ground and dumped it onto a sieve (H). Soil. These organisms thrive in the warm, moist environment of the rainforest and are able to decompose organic waste at a very rapid rate. During the Carboniferous period, fungi and bacteria had yet to evolve the capacity to digest lignin, and so large deposits of dead plant tissue accumulated during this period, later becoming the fossil fuels.

Ants and termites consume approximately one third of the organic litter; however, they do not digest everything. What would the forest look like?
