उत्तर
- A pyramid of energy is always upright. It can never be inverted because when energy flows from a particular trophic level, only 10% passes on as net energy to the next trophic level, and a large amount of energy is always lost as heat at each step.
- In smaller food chains, more energy is available than in the longer food chains.
- There are chain limitations of ecological pyramids. It assumes a simple food chain, something that almost never exists in nature.
- It does not accommodate a food web. Moreover, saprophytes are not given any place in ecological pyramids, even though they play a vital role in the ecosystem.
