Marn-Spiotta, E. & Sharma, S. Carbon storage in successional and plantation forest soils: a tropical analysis. 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 systemic approach for modeling soil functions. Ground foraging birds would starve because there would be no juicy, fatty, cockroaches to eat. Reforestation reverses many of the effects of deforestation, mainly in the topsoil, but such restoration can take decades and the resulting soil properties still deviate from those under natural forests. Regardless of rainfall, many lianas (woody vines) and herbaceous epiphytes (air plants, such as orchids) are common in these communities. Nature 372, 666669 (1994). 95, 97109 (2007). 352, 920 (2015).

Anthropogenic disturbances jeopardize biodiversity conservation Nature 489, 282285 (2012). Without them, the rainforest floor would be piled high with organic litter such as branches and leaves.
