Amount of energy transferred to the consumers by green plants in food chain is called:-

Options

A. Gross primary production
B. Net primary production
C. Standing crop
D. Standing state

Answer

To solve the question regarding the amount of energy transferred to consumers by green plants in a food chain, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Energy Transfer in Food Chains**:
- In a food chain, energy flows from producers (green plants) to consumers (herbivores, carnivores, etc.).

2. **Identify the Role of Green Plants**:
- Green plants are known as primary producers because they convert solar energy into chemical energy through photosynthesis.

3. **Define Gross Primary Production (GPP)**:
- The total amount of energy produced by green plants in a given area over a specific time period is termed as Gross Primary Production (GPP). This includes all the energy captured by photosynthesis.

4. **Consider Energy Losses**:
- Not all the energy produced by the plants is available to consumers. Some of this energy is used by the plants for their own metabolic processes, which is referred to as respiratory loss.

5. **Define Net Primary Productivity (NPP)**:
- The energy that remains after accounting for the energy used in respiration is called Net Primary Productivity (NPP). This is the amount of energy that is available for the next trophic level (consumers).

6. **Conclusion**:
- Therefore, the amount of energy transferred to consumers by green plants in a food chain is referred to as **Net Primary Productivity (NPP)**.

### Final Answer:
The amount of energy transferred to the consumers by green plants in a food chain is called **Net Primary Productivity (NPP)**.
