Question

There is a loss of energy as we go from one trophic level to the next; this limits the number of trophic levels in a food-chain.

• A. True
• B. False

Answer 1

The correct option is A

True

Everytime an organism consumes something, 90% of the energy is lost as heat during respiration, in digestion, etc. Only 10% is involved in building the body tissue. This 10% is passed to the next trophic level and so on. Thus, there is a loss of energy as we go from one trophic level to the next and this limits the number of trophic levels in a food-chain.
