Standing crop is - i. Biomass in a unit area ii. Number of living organism in unit area iii. Amount of nutrient such as carbon, nitrogen, calcium in unit area iv. Amount of Detritus in unit area
1 Only i
2 i & ii
3 i, ii, iii
4 i, ii, iv
Explanation:
Each trophic level has a certain mass of living material at a particular time called as the standing crop. The standing crop is measured as the mass of living organisms (biomass) or the number in a unit area.
