GEOLOGY

Detailed explanation-1: -Biodegradation is a biological process in which materials are decomposed by bacteria or other micro-organisms. It is an important process in ecology and waste management. Q. The organic substances from dead bodies of plants and animals are converted into inorganic substances by microorganisms.

Detailed explanation-2: -When plants and animals die, they become food for decomposers like bacteria, fungi and earthworms. 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: -Humus is dark, organic material that forms in soil when plant and animal matter decays.

Detailed explanation-4: -Bacteria and fungi are responsible for the decay of dead plants and animals. Decaying matter is recycled to grow plants.

Detailed explanation-5: -Decomposition is the natural process of dead animal or plant tissue being rotted or broken down. This process is carried out by invertebrates, fungi and bacteria. The result of decomposition is that the building blocks required for life can be recycled.
