If water pollution continues at its present rate, it will eventually

Options

A. Stop water cycle
B. Prevent precipitation
C. Make oxygen molecules unavailable to water plants.
D. Make nitrate molecules unavailable to water plants

Answer

### Step-by-Step Solution:

1. **Understanding Water Pollution**: Water pollution refers to the contamination of water bodies (like rivers, lakes, and oceans) due to harmful substances. This can affect the quality of water and the organisms that depend on it.

2. **Consequences of Water Pollution**: If water pollution continues at its current rate, it can lead to several adverse effects on aquatic ecosystems. One of the most significant impacts is the depletion of oxygen levels in water.

3. **Impact on Aquatic Life**: Aquatic plants and animals rely on oxygen dissolved in water for survival. If water pollution increases, it can lead to a decrease in oxygen levels, making it unavailable for aquatic plants and animals.

4. **Examples of Affected Organisms**: Many aquatic organisms, such as fish, crabs, and dolphins, can suffer from low oxygen levels. This can result in mass die-offs, where dead fish and other marine life wash up on beaches, indicating a severe ecological imbalance.

5. **Conclusion**: Therefore, if water pollution continues at its present rate, it will eventually make oxygen molecules unavailable to water plants and animals, leading to their death and the collapse of aquatic ecosystems.

### Final Answer:
If water pollution continues at its present rate, it will eventually make oxygen molecules unavailable to water plants.
