Options

A. Phytoplankton
B. Herbivores
C. Light
D. Bacteria

Explanation

To determine which of the following is not a biotic component, we need to understand the difference between biotic and abiotic components of an ecosystem.

### Step-by-Step Solution:

1. **Understand Biotic Components**:
- Biotic components are the living parts of an ecosystem. They include all organisms such as plants, animals, bacteria, fungi, and any other living entities.

2. **Understand Abiotic Components**:
- Abiotic components are the non-living parts of an ecosystem. These include physical and chemical factors like soil, water, air, temperature, and sunlight.

3. **Analyze the Options**:
- We need to look at the options provided in the question. Identify which of the options refers to a living organism (biotic) and which refers to a non-living entity (abiotic).

4. **Identify the Non-Biotic Component**:
- From the options, the one that represents a non-living entity will be the answer to the question. For example, if the options include "water," "tree," "lion," and "bacteria," then "water" is the non-biotic component.

5. **Conclusion**:
- After analyzing the options, we conclude that the option that is not a biotic component is the abiotic factor.

### Final Answer:
The answer is the option that represents a non-living component (e.g., water, soil, air).
