Which of the following is an abiotic components of the ecosystem?

Options

A. Bacteria
B. Humus
C. plants
D. Fungi.

Answer

To determine which of the following is an abiotic component of the ecosystem, we need to understand the distinction between abiotic and biotic components.

### Step-by-Step Solution:

1. **Define Ecosystem**: An ecosystem is a community of living organisms (biotic components) interacting with each other and their physical environment (abiotic components).

2. **Identify Components**: Ecosystems consist of two main types of components:
- **Biotic Components**: These are the living organisms, including plants, animals, bacteria, and fungi.
- **Abiotic Components**: These are the non-living physical and chemical factors in the environment, such as air, water, sunlight, soil, and minerals.

3. **List Examples of Abiotic Factors**: Common examples of abiotic factors include:
- Air
- Water
- Sunlight
- Temperature
- Soil
- Humus (though humus is often considered a product of biological activity, it is a component of soil and can be classified as abiotic in certain contexts).

4. **Analyze the Options**: If given a list of options, identify which ones are living organisms (biotic) and which ones are non-living (abiotic). For instance:
- If the options include bacteria, plants, or fungi, these are biotic.
- If the options include air, water, or humus, these are abiotic.

5. **Select the Correct Answer**: Based on the analysis, choose the option that represents an abiotic component of the ecosystem.

### Conclusion:
The correct answer will be the option that is a non-living entity, such as air, water, or humus.
