B. (Plants, Animals, Microorganisms) + Abiotic environment
C. Animal, plants and micro-organisms.
D. Abiotic factors

Answer

**Step-by-Step Solution:**

1. **Understanding the Ecosystem**: An ecosystem is defined as a community of living organisms (plants, animals, microorganisms) interacting with each other and with their physical environment (abiotic factors) in a specific area.

2. **Components of an Ecosystem**: An ecosystem consists of two main components:
- **Biotic Components**: These include all living organisms such as plants, animals, and microorganisms.
- **Abiotic Components**: These include non-living factors such as sunlight, water, air, minerals, and temperature.

3. **Analyzing the Statements**:
- **Statement 1**: "Community formed by various species present in a particular region."
- This is incorrect because it does not include abiotic factors, which are essential for defining an ecosystem.

- **Statement 2**: "Plants, animals, microorganisms plus abiotic environment."
- This is correct as it includes both the biotic and abiotic components of the ecosystem.

- **Statement 3**: "Animals, plants, and microorganisms."
- This is incorrect because it also fails to include abiotic factors.

- **Statement 4**: "Abiotic factors."
- This is incorrect as it only mentions abiotic components, ignoring the living organisms.

4. **Conclusion**: The correct statement regarding the ecosystem is the second option: "Plants, animals, microorganisms plus abiotic environment."
