Why is the energy flow diagram shaped like a pyramid?
The shape of the energy pyramid shows that there is enough biomass energy contained in the primary producers at the bottom to support the predators at the top, even though energy is lost at each level. Each level is the same height and the available energy is represented by the width of each level.
Why are flow of energy diagrams from one trophic stage to the next shaped like a pyramid?
The pyramidale shape of the trophic level come from the loss of energy between the levels.
Why is a trophic pyramid shaped like a triangle?
Ecological pyramids are diagrams which show the abundance of organisms at each trophic level along the food chain of an ecosystem. The shapes of ecological pyramids are somewhat triangular in shape because there are fewer consumers at each ascending tropic level.
Why is the pyramid shape used to describe the number of organisms in an ecosystem?
Generally, the population of predators is lower than prey. Ecological pyramids are drawn where predators are above prey and they show the population number of each organism shown. Therefore, as the pyramid rises, the population number of the organism decreases, ultimately resulting in a roughly pyramidal shape.
