Question

Write a short note on the ecological pyramids.

Answer 1

Ecological pyramids are diagrams that show the relationships among biomass, number, and energy at different trophic levels. They may be pyramids of numbers, biomass, or energy. Pyramids of numbers and biomass can be upright or inverted depending on the ecosystem, but energy pyramids are always upright, showing the rate of energy flow at successive levels. They represent the structure and function of an ecosystem’s food chain.
