All calculations for ecological pyramids must take into consideration all creatures in a certain trophic level because a sample space of a few numbers or species will give . As we go up the ecological pyramid more and more toxins get accumulated in the organisms.This is known as biomagnification. It is also known as Energy Pyramid. Ecological Pyramids Pyramid of Biomass Indicates the total dry mass of the organisms in each trophic level The size of the organism is over-emphasized and it can happen that the mass of level 2 is greater than that of level 1, because the productivity of level 1 is not taken into consideration Thus an enormous mass of grass is required to support a smaller mass of gazelle, which in turn . Ecological pyramids are a graphical representation to illustrate the relationship between different living organisms, based on their ecological position. pyramid, trophic pyramid, and food pyramid.
