Question
Which of the following is the ratio between energy flows at different points in a food chain?
- Ecological capacity
- Ecological efficiency
- Ecological assimilation
- Ecological potential
Hint:
Ecological efficiency
The correct answer is: Ecological efficiency
Ecological efficiency is the ratio between energy flows measured at different points in a food chain.
The ratio between energy flows measured at different points in a food-chain, usually expressed as a percentage. Many approaches have been devised to relate different aspects (e.g. intake, assimilation, and production). Two main categories of efficiencies are studied: (a)those of energy transfer between different trophic levels; and(b)those of energy transfer within a single trophic level.
