Assertion (A): In an ecosystem, the energy cannot be transferred from carnivores to herbivores, or herbivores to plants or plants to the sun.
Reasoning (R): In an ecosystem, the energy from the sun, fired by the plants, is transferred to herbivores and carnivores i.e. the energy flows in one direction only. Choose the correct option

Options

A. A is correct and R is the correct explanation of A.
B. A is correct and R is not the correct explanation of A.
C. A is correct and R is wrong.
D. A is wrong and R is correct.

Answer

To solve the question, we need to analyze the assertion and reasoning provided.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that in an ecosystem, energy cannot be transferred from carnivores to herbivores, herbivores to plants, or plants to the sun.
- This statement is fundamentally correct because energy transfer in an ecosystem follows a specific flow, typically from producers (plants) to consumers (herbivores and then carnivores).

2. **Understanding the Reasoning (R)**:
- The reasoning states that energy from the sun is captured by plants and then transferred to herbivores and carnivores, indicating that energy flows in one direction only.
- This is also correct as it describes the flow of energy in a food chain: sunlight → plants → herbivores → carnivores.

3. **Evaluating the Relationship**:
- The assertion is correct because it accurately describes the limitations of energy transfer in an ecosystem.
- The reasoning is also correct and serves as a valid explanation for the assertion since it outlines the one-way flow of energy.

4. **Conclusion**:
- Since both the assertion and reasoning are correct, and the reasoning correctly explains the assertion, the correct option is that both A and R are true, and R is the correct explanation of A.

### Final Answer:
Both Assertion (A) and Reasoning (R) are correct, and R is the correct explanation of A.
