Answer

**Step-by-Step Solution:**

1. **Understanding Ecology**: Start by defining ecology as a branch of biology. It focuses on the interactions that occur between organisms and their environment.

2. **Types of Interactions**: Recognize that these interactions can occur in various forms. They can be between organisms themselves, between organisms and their environment, or even between humans and other organisms.

3. **Components of the Environment**: Clarify that the environment consists of both biotic (living) and abiotic (non-living) factors. This means that ecology studies how living organisms interact with both types of factors.

4. **Living Community**: Note that ecology also considers the living community, which includes plants and animals. However, the question specifically asks about interactions, so we focus on organisms in general.

5. **Conclusion**: Based on the understanding of ecology and its focus on interactions, the correct answer to the question is that ecology deals with the interactions between organisms and their environment.

**Final Answer**: Ecology is the branch of biology that deals with interactions between organisms and their environment.
