Plant succession occurring in a water body is called .

Options

A. Hydrosere
B. Psammosere
C. Lithosere
D. Xerosere

Answer

**Step-by-Step Solution:**

1. **Understanding Plant Succession**: Plant succession refers to the gradual process by which ecosystems change and develop over time. It involves a series of stages where different plant communities replace one another.

2. **Identifying the Environment**: The question specifies that the succession occurs in a water body. Common examples of water bodies include rivers, ponds, and lakes.

3. **Defining the Type of Succession**: The type of succession that occurs in aquatic environments is distinct from terrestrial succession. In this context, we need to identify the term that describes this specific process.

4. **Introducing the Term**: The term used to describe plant succession occurring in a water body is "hydrosere." This term is derived from "hydro," meaning water, and "sere," which refers to a series of stages in ecological succession.

5. **Explaining the Process**: Hydrosere involves the colonization of plants in aquatic environments, which can lead to the gradual transformation of these water bodies into land communities as they undergo changes over time, such as drying out.

6. **Final Answer**: Therefore, the answer to the question is that plant succession occurring in a water body is called "hydrosere."
