Answer:
g/m2
Step-by-step explanation:
Biomass is the constant dry mass of organisms at a particular trophic level. In a stable ecosystem, the biomass decreases at each successive trophic level of the food chain. A diagrammatic representation of biomass in each trophic level in a food chain gives a pyramid of biomass.
g/m2 is the unit used in a pyramid of biomass. Kilocalories is Unit of measure for energy pyramids. The number of organisms in each trophic level gives a similar pyramid called pyramid of numbers.
