Question

At each tropic level in which form energy is lost

• A. Heat
• B. Chemical
• C. Light
• D. Electrical

Hint:

Energy flow in an ecosystem is always unidirectional and follows the Laws of Thermodynamics.

Answer 1

The Correct Option is A

Step 1: According to Lindeman's 10% law, only 10% of the energy is transferred from one trophic level to the next.
Step 2: The remaining 90% of the energy is consumed by the organism for metabolic activities (like respiration) or lost during the process.
Step 3: This lost energy is primarily released into the environment in the form of heat, which cannot be recycled back into the food chain.
