The highest amount of `CO_(2)` is evolved from

Options

A. Ocean
B. Rivers
C. Ponds
D. Forests

Answer

To determine where the highest amount of carbon dioxide (CO₂) is evolved from, we can analyze the options: ocean, rivers, ponds, and forest.

### Step-by-Step Solution:

1. **Understanding Carbon Dioxide in the Environment**:
- Carbon dioxide is a trace gas in the atmosphere and plays a crucial role in the carbon cycle. It is exchanged between the atmosphere, oceans, soil, rocks, and living organisms.

2. **Role of Photosynthesis**:
- Plants, through the process of photosynthesis, absorb CO₂ from the atmosphere and convert it into carbohydrates, releasing oxygen as a byproduct. This means that forests, which are primarily composed of plants, predominantly release oxygen, not CO₂.

3. **Examining Water Bodies**:
- Rivers and ponds are smaller water bodies compared to oceans. While they do contribute to the carbon cycle, their contribution is significantly less than that of oceans.

4. **The Ocean's Contribution**:
- Oceans are vast and play a major role in the carbon cycle. They absorb a large amount of CO₂ from the atmosphere and also release it back. The biological processes in oceans, including respiration by marine organisms and decomposition, contribute to the release of CO₂.

5. **Conclusion**:
- Among the options provided, the ocean is the largest contributor to the evolution of CO₂. Therefore, the correct answer is **ocean**.

### Final Answer:
The highest amount of CO₂ is evolved from the **ocean**.
