उत्तर
Decomposers include micro-organisms such as bacteria and fungi that obtain nutrients by breaking down the remains of dead plants and animals. They help in the breakdown of organic matter or biomass from the body of dead plants and animals into simple inorganic raw materials, such as carbon dioxide, water, and some nutrients. If decomposers are completely removed from the surface of earth then the remains of dead plants and animals will accumulate. The minerals and organic or inorganic material present in them will not be made again available for use. Thus it will result in the accumulation of wastes and also unavailability of raw materials. This will affect all the biogeochemical cycles and overall life on earth.
