Percentage energy transferred to higher trophic level in food chain is

Options

A. `1%`
B. `10%`
C. `90%`
D. `100%`

Answer

To solve the question regarding the percentage of energy transferred to the higher trophic level in a food chain, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the percentage of energy that is transferred from one trophic level to the next higher trophic level in a food chain.

2. **Recall the 10% Rule**: In ecological terms, there is a principle known as the "10% Rule" or "10% Law." This rule states that when energy is transferred from one trophic level to the next, only about 10% of the energy is passed on to the next level.

3. **Energy Loss**: According to the 10% Rule, 90% of the energy is lost during the transfer between trophic levels. This loss occurs due to various factors such as metabolic processes, heat loss, and other biological activities.

4. **Application of the Rule**: When energy flows from producers (like plants) to primary consumers (like herbivores), only 10% of the energy captured by the producers is available to the consumers. This pattern continues up the food chain.

5. **Conclusion**: Therefore, the percentage of energy transferred to the higher trophic level in a food chain is 10%.

6. **Select the Correct Option**: Based on the explanation, the correct answer to the question is option B, which states 10%.

### Final Answer:
The percentage energy transferred to the higher trophic level in a food chain is **10%** (Option B).
