Answer

To answer the question "Autoecology refers to," we will analyze the provided options and clarify the concepts of autoecology and its relation to other ecological terms.

### Step-by-Step Solution:

1. **Understanding Ecology**:
- Ecology is the study of interactions between organisms and their environment. It can be divided into two main branches: autoecology and synecology.

2. **Defining Autoecology**:
- Autoecology specifically focuses on the ecological study of individual species. It examines how a single species interacts with its environment, including factors like habitat, food sources, and adaptations.

3. **Defining Synecology**:
- In contrast, synecology studies groups of species and their interactions within communities. It looks at how different species coexist and interact with each other and their environment.

4. **Analyzing the Options**:
- Option 1: Plant ecology - This is a broader term that could encompass both autoecology and synecology.
- Option 2: Animal ecology - Similar to plant ecology, this term is also broader and does not specifically refer to autoecology.
- Option 3: Ecological study of individual species - This directly aligns with the definition of autoecology.
- Option 4: Ecological study of groups of species - This describes synecology, not autoecology.

5. **Conclusion**:
- Based on the definitions and analysis of the options, the correct answer is **the ecological study of individual species**.

### Final Answer:
Autoecology refers to the ecological study of individual species.
