1) Which ecological pyramid shows:
- The amount of energy at each trophic level
- The number of organisms at each trophic level
- The amount of living tissue at each trophic level
Justify your answer.
2) Why are energy pyramids always upright (never inverted)?
- Energy is lost as heat at each trophic transfer.
- Producers are always more efficient than consumers.
- Energy pyramids are always upright.
Justify your answer.
3) The graph compares three types of ecological pyramids for the same aquatic ecosystem:
- Pyramid of numbers
- Pyramid of biomass
- Pyramid of energy
Why might the biomass pyramid be inverted in this aquatic ecosystem?
- Phytoplankton reproduce very rapidly, despite low biomass.
- Energy pyramids are always upright.
- Consumers are more efficient at energy conversion.
- Phytoplankton have small standing population.
Justify your answer.
