Answer

To answer the question "Development of bare area without any form of life, in succession is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a term that describes the development of a bare area that lacks any form of life. This is a key aspect of ecological succession.

2. **Identifying Key Terms**: The term "bare area" refers to land that is barren and devoid of vegetation or life forms. The process of development in this context refers to ecological changes that occur over time.

3. **Defining Nudation**: The term that fits this description is "Nudation." Nudation is defined as the formation of a bare area where no life forms are present. This can occur due to various factors, including climatic changes, biotic factors, or topographic influences.

4. **Differentiating Related Terms**: It's important to distinguish nudation from other ecological terms. For example, "invasion" refers to the establishment of species in a bare area, which is not what the question is asking. Similarly, "interaction" refers to the relationships between species, which is also not relevant here.

5. **Final Answer**: Based on the definition and understanding of the terms, the correct answer to the question is "Nudation."
