In which of the following compartments of the global ecosystem would circulation of materials be affected by Earth’s revolution around the sun?

Options

A. Oceans
B. Fresh waters
C. Atmosphere
D. All of the above

Answer

To determine which compartments of the global ecosystem would have their circulation of materials affected by Earth's revolution around the sun, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Earth's Revolution**:
- Earth revolves around the sun in an elliptical orbit, taking approximately 365 days to complete one full revolution. This revolution affects various environmental factors.

2. **Identify Affected Factors**:
- As Earth moves in its orbit, the distance from the sun changes, which in turn affects temperature and climate. These changes can influence the circulation of materials in various compartments of the ecosystem.

3. **Consider the Compartments of the Global Ecosystem**:
- The global ecosystem consists of various compartments, including the atmosphere, hydrosphere (oceans and freshwater), and lithosphere (land). Each of these compartments interacts with biotic (living organisms) and abiotic (non-living elements) factors.

4. **Analyze the Impact on Each Compartment**:
- **Atmosphere**: Changes in temperature and climate due to Earth's position relative to the sun can affect weather patterns and air circulation.
- **Hydrosphere**: The temperature of oceans and freshwater bodies can vary with the seasons, influencing water circulation and the distribution of nutrients.
- **Lithosphere**: Changes in climate can affect soil composition, erosion rates, and the distribution of plant life, which in turn affects nutrient cycling.

5. **Conclusion**:
- Since all these compartments (atmosphere, hydrosphere, and lithosphere) experience changes due to Earth's revolution, we conclude that the circulation of materials in all these compartments is affected.

### Final Answer:
The circulation of materials would be affected in **all of the above compartments** of the global ecosystem.
