What important role do bacteria called decomposers play?
A
the return basic chemicals to the environment
B
they slow down food spoilage
C
kill harmful bacteria
D
produce vitamins in your intestine
Explanation: 

Detailed explanation-1: -They perform a valuable service as Earth’s cleanup crew. Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere. Imagine what the world would look like! More importantly, decomposers make vital nutrients available to an ecosystem’s primary producers-usually plants and algae.

Detailed explanation-2: -Decomposers or saprotrophs recycle dead plants and animals into chemical nutrients like carbon and nitrogen that are released back into the soil, air and water.

Detailed explanation-3: -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.

Detailed explanation-4: -Bacteria break down (or decompose) dead organisms, animal waste, and plant litter to obtain nutrients. But microbes don’t just eat nature’s waste, they recycle it. The process of decomposition releases chemicals (such as carbon, nitrogen, and phosphorus) that can be used to build new plants and animals.
