Biomass is the overall mass of organisms present in a trophic level of a food chain. The biomass is called fresh biomass if it refers to living organisms. Dry biomass is the mass of animals and plant materials after water removal by drying in an oven.
Ecological pyramids are some sort of diagram representing the number of organisms present in a trophic level of a food chain.
There are two types of ecological pyramids:
- Pyramid of numbers – This exemplifies the quantity of living beings present in each trophic level of a food chain that is unrelated to their mass.
- Pyramids of biomass: This shows the total mass of the organisms present in each trophic level of a food chain which is not respective to their numbers.
