Answer

To answer the question, "The sequential events from stage till climax stage in succession are called," we need to analyze the options provided and understand the concepts related to ecological succession.

### Step-by-Step Solution:

1. **Understand the Question**: We are looking for a term that describes the series of events that occur during ecological succession, from the initial stage to the climax stage.

2. **Analyze the Options**:
- **Option A: Assises**: This term refers to the establishment of plants or animals in a new habitat. It does not describe the sequential events in succession, so this option is incorrect.

- **Option B: Sear**: This term relates to the series of changes that occur during ecological succession. The first community that colonizes a bare area is called the pioneer community, and as succession progresses, it leads to a climax community. The term "Sear" encompasses these sequential changes, making it a strong candidate for the correct answer.

- **Option C: Nudation**: This term refers to the formation of bare land. While it is related to the beginning of succession, it does not describe the entire sequence of events leading to the climax stage, so this option is incorrect.

- **Option D: Migration**: This term refers to the movement of organisms from one place to another. It is not related to the process of succession, making this option incorrect as well.

3. **Conclusion**: After analyzing all the options, the term that best describes the sequential events from the initial stage to the climax stage in ecological succession is **Sear**.

### Final Answer:
The correct answer is **Sear**.
