Question

Choose the INCORRECT statement with respect to Pyramid of energy.

• A. When energy flows from a particular trophic level to the next trophic level, some energy is always lost as heat at each step.
• B. In smaller food chains, more energy is available than in the longer food chains.
• C. Energy increases while passing from producers to consumers.
• D. It is never inverted.

Hint:

Energy decreases, not increases, from producers to consumers.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
Only about 10 percent of energy passes from one trophic level to the next, the rest is lost as heat.

Step 2: Check each statement
Energy is lost as heat at each step, so (A) is true.
Shorter food chains have less loss, so (B) is true.
The pyramid of energy is always upright, so (D) is true.

Step 3: Find the incorrect one
Energy decreases from producers to consumers, so (C) saying it increases is incorrect.

Final Answer:
The incorrect statement is that energy increases from producers to consumers. \[ \boxed{\text{(C) }\text{Energy increases while passing from producers to consumers.}} \]
