Population ecology is the important branch of biology , because it links ecology to

Options

A. genetics and evolution
B. evolution and applied biology
C. gentics and embryolpogy
D. evolution and physiology

Answer

**Step-by-Step Solution:**

1. **Understanding Population Ecology**: Begin by defining what population ecology is. It is a subfield of ecology that focuses on the dynamics of species populations and their interactions with the environment.

2. **Identifying Key Components**: Recognize that population ecology examines not just the populations themselves but also how these populations evolve over time and how genetic factors influence their survival and reproduction.

3. **Linking to Other Biological Fields**: Consider how population ecology connects to other branches of biology. The two most relevant fields are genetics and evolution. Genetics deals with the hereditary aspects of organisms, while evolution explains how species change over time.

4. **Conclusion**: Based on the understanding that population ecology studies the interactions within species populations and their evolutionary changes, it can be concluded that the branch of biology it links to is **genetics and evolution**.

5. **Final Answer**: Therefore, the correct answer to the question is that population ecology links ecology to **genetics and evolution**.
