As a source of manure (fertilizer enhancers). In turn for giving them a place to live, the bacteria return the favor by fixing nitrogen for the plants to use. Decomposers are especially important in retaining nutrients in their cells thus preventing loss of those nutrients from the root zone. They free up the physical space an dead organisms takes up.

The reserve has seen more than thirty species of wading birds. The tunneling action of earthworms also helps to break up and aerate the soil. Soil bacteria such as Bacillus subtilis and Pseudomonas fluorescens are extensively involved at the decomposer level as well. When a decomposer breaks down decaying organic material they produce waste material. Finally, we discuss how the sun's energy is passed on from the rabbit and the grass to the decomposers when the rabbit and grass dies.

Decomposers are like the housekeepers of an ecosystem. These organisms are called detritivores. These nutrients will help plants grow, which will then feed herbivores, then first order heterotrophs, then second order (usually omnivores), then tertiary consumers, or obligate carnivores. Milk is an excellent growth medium for numerous bacteria, and the bacteria can increase rapidly in numbers unless the milk is properly processed. They take things that would otherwise be trash - dead organisms - and recycle the nutrients in them. (CBSE 2008) Answer: Bacteria and fungi are called decomposers as they break down the dead remains and waste of organisms.
