Read the given statements and select the correct option.
Statement 1: Net primary productivity is less than the gross primary productivity.
Statement 2 : Net primary productivity is equal to the gross primary productivity minus the respiration losses.

Options

A. Both statements 1 and 2 are correct.
B. Statement 1 is correct but statement 2 is incorrect.
C. Statement 1 is incorrect but statement 2 is correct.
D. Both statement 1 and 2 are incorrect.

Explanation

To solve the question, we need to evaluate the two statements regarding net primary productivity (NPP) and gross primary productivity (GPP).

### Step-by-Step Solution:

1. **Understanding Gross Primary Productivity (GPP)**:
- GPP refers to the total amount of organic matter (or biomass) produced by photosynthesis in a given area over a specific time period. It represents the total energy captured by photosynthetic organisms.

2. **Understanding Net Primary Productivity (NPP)**:
- NPP is the amount of organic matter that remains after the energy used by producers for respiration is subtracted from GPP. It represents the energy available for consumption by herbivores and other organisms in the ecosystem.

3. **Evaluating Statement 1**:
- Statement 1 claims that "net primary productivity is less than the gross primary productivity." This is true because NPP is derived from GPP by subtracting the energy lost through respiration. Therefore, NPP must always be less than GPP.

4. **Evaluating Statement 2**:
- Statement 2 states that "net primary productivity is equal to gross primary productivity minus the respiration losses." This is also true as it directly reflects the relationship between NPP and GPP. The formula is:
\[ NPP = GPP - \text{Respiration Losses} \]

5. **Conclusion**:
- Both statements are correct. Therefore, the correct option is that both statements are true.

### Final Answer:
Both Statement 1 and Statement 2 are correct. The answer is Option A.
