Question

17. Energy is used and conveyed from one trophic level to another in a food chain. This is
called flow of energy. Green plants capture about 1% of the solar energy incident on the
Earth through the biochemical process of photosynthesis. A part of this trapped energy is
used by plants in performing their metabolic activities and some energy is released as
heat into the atmosphere. The remaining energy is chemical energy stored in the plants as
"carbohydrates'. When plants are eaten up by herbivores, the chemical energy stored in
the plants is transferred to these animals. These animals (herbivores) utilize some of this
energy for metabolic activities, some energy is released as heat and the remaining energy
is stored. The process of energy transferred is similarly repeated with carnivores and so
on.
In a food chain, 10,000 joules of energy is available to the producer. How much
energy will be available to the secondary consumer to transfer it to the tertiary
consumer ?​

Answer 1

Answer:

In a food chain, if 10,000 joules of energy are available at the producer level, only 10 joules of energy would be transferred from the secondary consumer to the tertiary consumer. This is because of the Ten-Percent Law.
