Question

The pyramid of energy in an aquatic ecosystem is

• A. Always upright
• B. Always inverted
• C. Bell-shaped
• D. None of the these

Answer 1

The correct option is A

Always upright

The pyramid of energy in an aquatic ecosystem is always upright because at each transfer about 80-90% of the energy available at a lower trophic level is used up to overcome its entropy and to perform metabolic activities. Only 10% of the energy is available to the next trophic level.
