Answer:
An ecological pyramid is a graphical representation of the relationship between different organisms in an ecosystem. Each of the bars that make up the pyramid represents a different trophic level, and their order, which is based on who eats whom, represents the flow of energy.
An ecological pyramid is the graphic representation of an ecological parameter (number, biomass or energy). The rate of energy flow in an ecosystem will be considered in drawing the pyramid of energy, the dry weight will be considered in drawing the pyramid of biomass and number of individuals is considered for drawing the pyramid of a number. The terrestrial system consists of grassland and forests. Pyramid of biomass in a grassland is upright. The biomass decreases with each higher trophic level from plants to herbivores to carnivores. The least biomass is seen in highest trophic level, that is predators like foxes and eagles.
