Select the WRONG statement regarding energy flow in an ecosystem.

Options

  1. AEnergy flow in one direction only
  2. BAbout 1-5% of the energy reaching the ground is converted by the green plants into chemical energy.
  3. CEnergy requirement for maintenance of body gradually decreases in successive trophic levels.
  4. DOnly 10% of the gross productivity of producers is entrapped by herbivores for their body building.

Correct answer

C. Energy requirement for maintenance of body gradually decreases in successive trophic levels.

Step-by-step solution

A community of organisms interacting with abiotic component in a particular region/area will be called as ecosystem. The living and non-living components are linked together by the nutrient cycles and energy flow through each trophic level. In a typical food chain, the energy that is transferred from one trophic level to the next is always unidirectional and never forms a cyclical pattern. The main source of energy is the sun (solar energy/free energy), which is used by producers to make food and then it is consume
