Question

Q. Assertion A: Energy flows linearly in the environment.

Reason R: Energy flows from one nutrient stage to the next, and some energy is constantly lost during the process.

• A. A and B both are correct and B is the reason for A.
• B. A and B are correct and B is the reason for A.
• C. A is correct and B is wrong.
• D. A is wrong but B is correct.

Answer 1

The correct option is B A and B are correct and B is the reason for A.

Explanation:

• Energy Flow is linear/unidirectional in an ecosystem because Only 1% of solar energy falling on the leaves of producers gets converted into food energy through photosynthesis and is made available to the next trophic level of consumers.
• After consumers eat, producers add a lot of energy to the environment in the form of heat. Energy used is also used by the consumer for digestion, growth, reproduction and other activities. Only 10% of energy is turned into its own body and is made available for the next level of consumers[10% Law]
