What Is the Role of Decomposers in the Food Chain

Producers who make their own food using photosynthesis or chemosynthesis make up the bottom of the trophic pyramid. A food web is all of the food chains in an ecosystem.

A food chain outlines who eats whom.

. Thus food chains start with primary producers and end with decay and decomposers. Saprotrophic nutrition s æ p r ə ˈ t r ɒ f ɪ k-p r oʊ- or lysotrophic nutrition is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed dead or waste organic matterIt occurs in saprotrophs and is most often associated with fungi for example Mucor and soil bacteriaSaprotrophic microscopic fungi are sometimes called saprobes. Since decomposers recycle nutrients leaving them so they can be reused by primary producers they are sometimes regarded as occupying their own trophic level.

Each link in this chain is food for the next link. Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. Decomposition or rot is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide water simple sugars and mineral saltsThe process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphereBodies of living organisms begin to decompose.

Some animals eat plants and some animals eat other animals. A food chain shows how each living thing gets its food. Decomposers are often left off food webs but if included they mark the end of a food chain.

For example a simple food chain links the trees and shrubs the giraffes that eat trees and shrubs and the lions that eat the giraffes.
