The correct Answer is:
To solve the question regarding the role of phytoplanktons in the hydrosere, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Hydrosere**: - The hydrosere refers to a type of ecological succession that occurs in aquatic environments. It starts in water bodies and progresses towards drier conditions. **Hint**: Remember that hydrosere is a type of ecological succession specifically in wet areas. 2. **Identifying Phytoplanktons**: - Phytoplanktons are microscopic plants that float in water. They are the first organisms to colonize aquatic environments in the early stages of succession. **Hint**: Think of phytoplanktons as the "pioneers" of aquatic ecosystems. 3. **Role of Phytoplanktons in Succession**: - In the hydrosere, phytoplanktons serve as the pioneer community. They are the first organisms to establish themselves in the newly formed or disturbed aquatic environment. **Hint**: Pioneer species are crucial for starting the process of ecological succession. 4. **Progression of Succession**: - As succession progresses, phytoplanktons are gradually replaced by other plant communities, such as submerged plants, floating plants, and eventually larger vegetation, leading to a climax community. **Hint**: Climax communities are typically characterized by larger, more complex plants, not by phytoplanktons. 5. **Conclusion**: - Based on the role of phytoplanktons in the hydrosere, they are classified as members of the pioneer community, not the climax community. **Hint**: Focus on the definitions of pioneer and climax communities to clarify their roles in succession. ### Final Answer: Phytoplanktons in the hydrosere constitute members of the **pioneer community**.

To solve the question regarding the role of phytoplanktons in the hydrosere, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Hydrosere**: - The hydrosere refers to a type of ecological succession that occurs in aquatic environments.
