Total amount of energy trapped by green plants in food is called:-

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks for the term that describes the total amount of energy trapped by green plants during the process of photosynthesis.

2. **Identifying Key Terms:**
- **Photosynthesis:** This is the process by which green plants convert solar energy into chemical energy in the form of glucose.
- **Energy Trapped:** This refers to the total energy that is converted and stored by plants.

3. **Analyzing the Options:**
The options provided are:
- Gross Primary Production
- Net Primary Production
- Standing Crop
- Standing State

4. **Defining Each Option:**
- **Gross Primary Production (GPP):** This is the total amount of solar energy converted into chemical energy by plants during photosynthesis.
- **Net Primary Production (NPP):** This is the amount of energy that remains after the plants have used some of the energy for their metabolic activities. It is calculated as GPP minus the energy used by the plants.
- **Standing Crop:** This refers to the total biomass (organic matter) present in an ecosystem at a given time.
- **Standing State:** This represents the amount of inorganic nutrients in an ecosystem, indicating the non-living components.

5. **Determining the Correct Answer:**
Since the question specifically asks for the total amount of energy trapped by green plants, the correct term is **Gross Primary Production (GPP)**, as it encompasses all energy converted during photosynthesis.

6. **Conclusion:**
The total amount of energy trapped by green plants in food is called **Gross Primary Production**.
