The key elements that determine differences in environmental conditions of different habiats include

Options

A. temperature
B. light
C. soil
D. all of these

Explanation

To answer the question regarding the key elements that determine differences in environmental conditions of different habitats, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Environment**:
- The environment consists of both biotic (living) and abiotic (non-living) factors that influence organisms.

2. **Identifying Biotic and Abiotic Factors**:
- Biotic factors include all living organisms such as plants, animals, and microorganisms.
- Abiotic factors include non-living components such as temperature, water, light, and soil.

3. **Focusing on Abiotic Factors**:
- The abiotic factors play a crucial role in determining the environmental conditions of different habitats.
- The four major abiotic factors that significantly influence habitats are:
- Temperature
- Water
- Light
- Soil

4. **Analyzing the Options**:
- The question provides options including temperature, light, soil, and "all of these."
- Since temperature, light, and soil are all key abiotic factors that influence environmental conditions, the correct answer must include all of them.

5. **Conclusion**:
- Therefore, the key elements that determine differences in environmental conditions of different habitats include temperature, light, and soil. Thus, the correct answer is "all of these."

### Final Answer:
The key elements that determine differences in environmental conditions of different habitats include **all of these** (temperature, light, and soil).
