EVERYDAY SCIENCE

Detailed explanation-1: -Bacteria and fungi are called decomposer because they break down the dead and decaying organic matter into a simpler substance. It provides the nutrients back to the soil.

Detailed explanation-2: -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.

Detailed explanation-3: -They aid in the recycling of nutrients. They make room for a new life in the biosphere by decaying the dead. They contribute to the reintroduction of different elements into moisture, soil, and air for reuse by producers such as crop plants.

Detailed explanation-4: -Bacillus subtilis and Pseudomonas fluorescens are examples of decomposer bacteria. Additions of these bacteria have not been proved to accelerate formation of compost or humus in soil. Rhizobium bacteria can be inoculated onto legume seeds to fix nitrogen in the soil.

Detailed explanation-5: -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.
