What is the role of bacteria and fungi as decomposers and role do bacteria and fungi decomposers play in the flux of energy and matter through a named ecosystem?
Bacteria and fungi are decomposers because they break down the dead and decaying organic matter into simpler substances such as carbon dioxide, water, simple sugars, and mineral salts and provide the nutrients back to the soil. They break down dead plant and animal matter so the nutrients in them are recycled back into the ecosystem to be used again. Fungi are the main decomposers in many ecosystems, particularly in forests. One of their main functions is to help release nitrogen and phosphorous from dead decaying matter.
