NEET BIOLOGY

Detailed explanation-1: -Biomass: The total amount of organic matter present in an ecosystem is called Biomass. The word organic matter refers to food that comes from living organisms such as plants and animals. In an ecosystem, the organic matter is abundant and is circulated to soil microorganisms by decomposition.

Detailed explanation-2: -The amount of living matter (biomass) present at every trophic level is called standing crop.

Detailed explanation-3: -Organic matter consists mainly of the living organisms in the soil (“the living”), the fresh residue (“the dead”), and the well-decomposed (or burned) material physically or chemically protected from decomposition (“the very dead”).

Detailed explanation-4: -The biomass is the mass of living biological organisms in a given area or ecosystem at a given time. Biomass can refer to species biomass, which is the mass of one or more species, or to community biomass, which is the mass of all species in the community. It can include microorganisms, plants or animals.

Detailed explanation-5: -Decomposition is a biological process that includes the physical breakdown and biochemical transformation of complex organic molecules of dead material into simpler organic and inorganic molecules (Juma, 1998).
