The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: The assertion states that "Estuary constitutes one of the most productive ecosystems." - **Explanation**: Estuaries are areas where freshwater from rivers meets and mixes with saltwater from the ocean. This unique environment supports a diverse range of species and is rich in nutrients, making it one of the most productive ecosystems on Earth. 2. **Evaluating the Reason**: The reason given is "It represents a transition zone between two populations of a species." - **Explanation**: While estuaries do serve as transition zones, they are primarily transition zones between two ecosystems (freshwater and marine), not specifically between two populations of a single species. This makes the reason incorrect in the context of the assertion. 3. **Determining the Truth Value**: - The assertion is true because estuaries are indeed very productive ecosystems. - The reason is false because it inaccurately describes the nature of estuaries as transition zones between populations of a species rather than between ecosystems. 4. **Conclusion**: Since the assertion is true and the reason is false, we conclude that the correct answer is that the assertion is true, but the reason is false. ### Final Answer: - The assertion is true, and the reason is false.
