Question
There is a gradual increase in the amount of energy transferred from one trophic level to the next trophic level in a food chain
- True
- False
Hint:
Only a fraction of the energy available at one trophic level is transferred to the next trophic level.
The correct answer is 'False'.
The correct answer is ‘decrease’.
- Because energy is lost as metabolic heat during the transmission of energy, the amount of energy decreases from one trophic level to the next.
- It is ineffective to transfer energy between trophic levels.
- Only around 10% of the net productivity at one level is carried over to the next level as net productivity.
