Question

Which of the following is true about the efficiency of energy transfer in an ecosystem?
a. The more energy the organism requires, the more efficient the energy transfer.
b. All energy transfers have the same efficiencies.
c. The less energy the organism requires, the more efficient the energy transfer.
d. The most efficient energy transfers are in large, warm-blooded animals.

Answer 1

What is true of efficiency of energy transfer in an ecosystem is that the less energy the organism requires the more efficient the nergy transfer - c.

The reason for this is the fact that with large animals and organisms which need a lot of energy, there is always a surplus which gets lost. 

Answer 2

Answer;

C. The less energy the organism requires, the more efficient the energy transfer.

Explanation;

• All living organisms need energy in one form or another since energy is required to drive metabolic process in various metabolic pathways, which organisms rely on for survival.
• Food chains show how energy flows in an ecosystem from the lowest trophic level to the highest level and also how efficiently organisms acquire this energy, use it and how much energy remains for use or how much energy is transferred to the next trophic level.
• The less energy an organism requires, the more efficient the energy transfer as more energy is conserved.
