A pyramid of biomass is based on the number of organisms at each trophic level
Open in App
Solution
The correct option is B False
The pyramidal representation of trophic levels of different organisms based on their ecological position [producer to final consumer] is called as an ecological pyramid. Pyramid of biomass is usually determined by collecting all organisms occupying each trophic level separately and measuring their dry weight. The biomass of a species is expressed in terms of fresh or dry weight. Measurement of biomass in terms of dry weight is more accurate. Each trophic level has a certain mass of living material at a particular time called as the standing crop.So the given statement is false'.
