NEET BIOLOGY

Detailed explanation-1: -In ecology, productivity is the rate at which energy is added to the bodies of organisms in the form of biomass. Biomass is simply the amount of matter that’s stored in the bodies of a group of organisms.

Detailed explanation-2: -Biomass is directly proportional to net primary productivity. This is because net primary productivity measures the organic material stored by the plant after metabolism has occurs. This means that if primary productivity is high biomass will also be high and the reverse is also true.

Detailed explanation-3: -Productivity within an ecosystem can be defined as the percentage of energy entering the ecosystem incorporated into biomass in a particular trophic level. Biomass is the total mass in a unit area (at the time of measurement) of living or previously-living organisms within a trophic level.

Detailed explanation-4: -The primary productivity of an ecosystem depends upon variety of envionmental factors such as light, temperature, water, precipitation etc. 2. It also depends upon the availability of nutrients and the availability of plants to carry out photosynthesis.
