The correct Answer is:

To solve the question, we need to evaluate each of the three statements provided and determine their correctness. ### Step-by-Step Solution: 1. **Evaluate Statement I: "Euryhaline can tolerate a wide range of salinity."** - Euryhaline organisms are indeed capable of surviving in environments with varying salinity levels. This statement is correct. Examples of euryhaline organisms include certain species of crabs and fish that can thrive in both freshwater and saltwater. 2. **Evaluate Statement II: "The productivity and distribution of plants are heavily dependent on water."** - Water is essential for plants for various metabolic processes, including photosynthesis, nutrient uptake, and transpiration. The availability of water directly influences plant productivity and their geographical distribution. Therefore, this statement is also correct. 3. **Evaluate Statement III: "Many freshwater animals cannot live for long in seawater, but sea animals can live in freshwater for a long time because of osmotic balance."** - This statement is misleading. Freshwater animals are adapted to low salinity environments and cannot survive in high salinity (seawater) due to osmotic stress. Conversely, marine animals are adapted to high salinity and generally cannot survive in freshwater for extended periods due to osmotic imbalance as well. Thus, this statement is incorrect. ### Conclusion: - Statement I is correct. - Statement II is correct. - Statement III is incorrect. Therefore, the correct statements are I and II. ### Final Answer: The correct statements are I and II. ---
