Solution

The correct option is A Total living material

Each trophic level in an ecosystem 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) in a unit area. The biomass of a species is expressed in terms of dry weight. Standing crop is the total biomass of an ecosystem at a given time.
