The correct Answer is:
To solve the question regarding how fish avoid summer-related problems such as heat and desiccation, we will analyze the options provided and determine the correct answer step by step. ### Step-by-Step Solution: 1. **Understanding the Problem**: The question asks how fish cope with summer-related issues like high temperatures and drying out (desiccation). 2. **Evaluating the First Option - Hibernation**: - Hibernation is a state that many animals enter to survive cold winters. It involves a significant reduction in metabolic activity and is not applicable to summer conditions. - **Conclusion**: Hibernation is not the correct answer for summer-related problems. 3. **Evaluating the Second Option - Diapause**: - Diapause refers to a period of suspended development that occurs in certain organisms, particularly insects, during unfavorable environmental conditions. While it is a survival strategy, it is more associated with cold or adverse conditions rather than specifically summer heat. - **Conclusion**: Diapause is not the correct answer for summer-related problems. 4. **Evaluating the Third Option - Estivation**: - Estivation is a form of prolonged dormancy that occurs in response to hot and dry conditions. It allows organisms, including fish, to survive periods of extreme heat and desiccation by reducing metabolic activity. - **Conclusion**: Estivation is the correct answer for how fish avoid summer-related problems. 5. **Evaluating the Fourth Option - Dormancy**: - Dormancy is a general term that describes a state where normal physical functions are suspended or slowed down. While it can apply to various conditions, it does not specifically address the summer heat and desiccation issues faced by fish. - **Conclusion**: Dormancy is not specific enough to be the correct answer. ### Final Answer: The correct answer is **Estivation**. Fish undergo estivation to avoid summer-related problems such as heat and desiccation. ---

Bharath went to his grandfather’s house in winter this year. As usual he went for fishing. His grandmother told him there will be no fishes in the lake. He noticed that it was more difficult to find fishes in winter. The fishes were deep inside the river. Whereas in summer they were on the surface and hence he was able to catch fishes. (a) Why are fishes on the surface in water than in the depth in summer? Srisha wanted to keep ice creams without melting. So he had to keep it on ice taken in a container. His grandmother advised him to pour salt on the ice. (a) Why? (b) What value can be derived from this?
