Options

A. Species diversity
B. Genetic diversity
C. Ecosystem diversity
D. All of the above

Explanation

**Step-by-Step Solution:**

1. **Understanding Ecological Diversity**: Ecological diversity refers to the variety of ecosystems within a particular area. It encompasses the different habitats, communities, and ecological processes that occur within those ecosystems.

2. **Components of Ecological Diversity**: Ecological diversity includes several key components:
- **Ecosystem Diversity**: This refers to the variety of ecosystems in a given area, such as forests, wetlands, grasslands, and deserts.
- **Species Diversity**: This involves the variety of species within an ecosystem, including the number of different species and their relative abundance.
- **Genetic Diversity**: This refers to the variation of genes within a particular species, which is important for the adaptability and survival of species.

3. **Identifying the Correct Answer**: The question asks what ecological diversity includes. While species and genetic diversity are important, ecological diversity specifically focuses on the variety of ecosystems and the interactions within those ecosystems. Therefore, the correct answer is **ecosystem diversity**.

4. **Conclusion**: Ecological diversity encompasses a broader range of interactions and processes compared to species and genetic diversity, making it the most comprehensive aspect of biodiversity.

**Final Answer**: Ecological diversity includes ecosystem diversity.
