why does the importance of decomposers in a forest
Answers
Answer:
The role of the decomposer in any ecosystem is to recycle nutrients once organisms die and nutrients in waste.
Explanation:
The main role of the decomposer in any ecosystem is to recycle nutrients once organisms die and recycle nutrients in waste. These nutrients are then released into the ecosystem and are available again for use.
Thus, decomposers make nutrients available again but their role is also important in terms of space. They free up the physical space an dead organisms takes up.

Answer:
Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.
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.
Explanation:
The group of organisms called decomposers forms the final link in the food chain. They break down dead animals and plants and return vital nutrients to the soil. Some decomposers, like fungi, can be seen without a microscope, but much of the decomposition process is carried out by microscopic bacteria
The organisms that occupy the decomposer level of a biome are essential to life on Earth. 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. They do this through a series of specialized proteins and enzymes in their cell walls and hyphae (root-like filaments). Fungi are particularly suited to penetrating large pieces of decaying matter like wood with their hyphae and breaking it down with lignin-digesting enzymes. Bacteria are also key organisms at the decomposer level.
There are other organisms in nature such as earthworms, some insects, sea cucumbers and woodlice that also break down decaying material, but they need to ingest it first unlike fungi that use chemical and biological processes. These organisms are called detritivores.

Food Chain
Organisms in this level of the food chain provide nutrients for the producers (plants) who in turn are eaten by the consumers in the next level who are then eaten by tertiary consumers. Fungi release enzymes that break down dead organic matter and release it into the soil while earthworms excrete nutrient-rich waste that adds more vitality to the soil. 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. They are critical for the early stages of decomposition before fungi and earthworms take over. Bacteria not only feed on dead leaves and weeds but they also fix nitrogen in the soil so it is not lost to the air or water (see below).
