What percent of energy is transmitted from one trophic level to another in a food chain?

0.1

The correct answer is Option (2)- 0.1

The percentage of energy transferred from one trophic level to another in a food chain is about 10%. This is known as the 10% rule or Lindeman's ecological efficiency.

Here's why only 10% of energy is transferred:

• Organisms use energy for their biological processes like respiration and movement. This energy is lost as heat and cannot be used by the next trophic level.The majority of energy is lost as heat during metabolic processes, and only a fraction is passed on to the next trophic level in the form of biomass. Therefore, the correct option is: 0.1

So, as energy flows through a food chain, the amount of available energy decreases at each trophic level. This limits the number of trophic levels that can be supported in an ecosystem.
