Write a short note on the pyramid of numbers and a pyramid of biomass.
Pyramid of Numbers: It is arranged from the lower trophic levels at the bottom to the higher trophic levels above and shows the number of individuals at each level. Mostly, these pyramids have a wider base (higher producer population)
Pyramid of Biomass: It is arranged from the lower trophic levels at the bottom to higher trophic levels above and shows the biomass (dry weight) at each level. Mostly, these pyramids have a wider base (higher producer population).
