Question

With reference to food chains, what is an ecological pyramid?

Answer 1

An ecological pyramid is a diagram that shows the differences among trophic levels in an ecosystem. It uses stacked rectangular boxes to represent the relative amount of individuals, biomass, or energy flow at each level from producers at the base to consumers above. These pyramids illustrate the relationship between biomass, numbers, or energy content across trophic levels. Pyramids of biomass and numbers may be upright or inverted, but energy pyramids are always upright. They reflect energy transfer and productivity through the food chain.
