C. C) Soil an light
D. D) Biotic and abiotic components

Answer

**Step-by-Step Solution:**

1. **Understanding the Ecosystem**: An ecosystem is a complex network that includes all living organisms (plants, animals, microorganisms) and their physical environment (air, water, soil, light).

2. **Identifying Components**: Ecosystems are made up of two main types of components:
- **Biotic Components**: These are the living parts of an ecosystem, including all forms of life such as plants, animals, and microorganisms.
- **Abiotic Components**: These are the non-living parts of an ecosystem, which include elements like air, water, soil, and light.

3. **Interrelationship**: There is a significant interaction between biotic and abiotic components in an ecosystem. For example, plants (biotic) require sunlight (abiotic) for photosynthesis, and animals (biotic) depend on plants (biotic) for food.

4. **Conclusion**: Given the options provided in the question, the correct answer is that an ecosystem has biotic and abiotic components. This interaction is essential for the functioning of the ecosystem.

**Final Answer**: Option D - Biotic and Abiotic Components.
