In a food chain, the total amount of living material is depicted by

Options

(a) pyramid of energy
(b) pyramid of biomass
(c) pyramid of numbers
(d) all of the above

Correct Answer:

pyramid of biomass

Explanation:

Pyramid of biomass is a diagrammatic representation of the amount of organic material measured in grams of drymass per square metre found in a particular habitat at ascending level of the food chain. A pyramid of biomass is a more accurate representation of the flow of energy through a food chain than pyramid of number, but seasonal variations may change the values for the amount of biomass.
