An ecosysten includes

Options

A. all living organisms
B. non-living objects
C. both living organisms and non-living objects
D. sometimes living organisms and sometimes non-living objects

Explanation

**Step-by-Step Solution:**

1. **Define Ecosystem**: An ecosystem is a geographic area where living organisms and non-living components interact with each other.

2. **Identify Components**: An ecosystem consists of two main components:
- **Abiotic Components**: These are the non-living parts of the ecosystem. Examples include air, water, soil, sunlight, and minerals.
- **Biotic Components**: These are the living parts of the ecosystem. Examples include plants, animals, fungi, and microorganisms.

3. **Interaction**: The abiotic and biotic components of an ecosystem interact and work together to sustain life. For instance, plants (biotic) require sunlight and water (abiotic) to grow.

4. **Evaluate Options**: If the question provides multiple options regarding what an ecosystem includes, we need to analyze each:
- **Option A**: "All living organisms" - This is incorrect because it only mentions biotic components and ignores abiotic components.
- **Option B**: "Only non-living objects" - This is incorrect as it only mentions abiotic components and ignores biotic components.
- **Option C**: "Both living organisms and non-living objects" - This is correct as it includes both biotic and abiotic components.

5. **Conclusion**: The correct answer is Option C, which states that an ecosystem includes both living organisms and non-living objects.
