A. The amount of nutrients, such as carbon, nitrogen, phosphorus, calcium, etc., present in the soil at any given time, is referred to as the standing state. B. Secondary productivity is defined as the rate of formation of new organic matter by consumers. C. Each trophic level has a certain mass of living material at a particular time called as the standing crop. D.

It is calculated by subtracting the energy used by plants for respiration (R) from the gross primary productivity (GPP): GPP - R = NPP. |
