Pyramid of energy in a pond ecosystem is always:
- AInverted
- BUpright
- CIrregular
- DLinear
✓
Answer
- Upright
Explanation:
The pyramid of energy is the ecological pyramid that gives a graphic representation of the amount of energy trapped by different trophic levels per unit area.
It is always upright because during the transfer of energy from one trophic level to the next a lot of wastage occurs in feeding, digestion, assimilation, and respiration i.e metabolism at each trophic level.
Hence organisms of each trophic level have more energy than each succeeding trophic level and less energy than organisms at the previous trophic level.
