Decomposers only break down dead plants

|
|
They do not help other organisms in an ecosystem
|
Detailed explanation-1: -Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.
Detailed explanation-2: -Different decomposers Fungi release chemicals to break down dead plants or animals into simple substances. They absorb some of these substances for growth, but others enter the soil. Earthworms digest rotting plant and animal matter as they swallow soil.
Detailed explanation-3: -Decomposers can recycle dead plants and animals into chemical nutrients such as carbon and nitrogen that are released back into the soil, air and water as food for living plants and animals. So, decomposers can recycle dead plants and animals and help keep the flow of nutrients available in the environment.
Detailed explanation-4: -Decomposers are bacteria and fungi which break down dead plant and animal matter. They secrete enzymes on the surface of the dead organisms to break them down and then absorb the digested, smaller food molecules.
Detailed explanation-5: -Decomposers in ecosystems act as environmental cleaners by decaying dead plants and animals. They aid in the recycling of nutrients. They make room for a new life in the biosphere by decaying the dead.
