Answer 2

Explanation:

The amount of Biomass produced per unit area by the plants in a community is called the primary productivity of that community.It is expressed either in units of energy or dry organic matter or carbon.The total fixation of energy by the process of photosynthesis is referred to as gross primary productivity and the proportion that is left after respiration losses is called net primary productivity.
