In water bodies, excessive amount of chemicals cause increased growth of:

Options

A. Fungi
B. Algae
C. Bacteria
D. Pathogens

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the effect of excessive chemicals in water bodies. We need to identify what organism or growth is promoted by these chemicals.

2. **Identifying the Chemicals**: In many cases, the excessive chemicals in water bodies are nutrients like nitrogen and phosphorus. These are often found in fertilizers, sewage, and industrial waste.

3. **Effects of Excess Nutrients**: When these nutrients are present in high amounts, they lead to a process called eutrophication. This process stimulates the growth of certain organisms in the water.

4. **Growth of Algae**: The primary organisms that benefit from the excess nutrients are algae. Algae can grow rapidly and form large blooms, sometimes referred to as algal blooms.

5. **Consequences of Algal Blooms**: While algae are a natural part of aquatic ecosystems, excessive growth can block sunlight from reaching other aquatic plants, disrupt the ecosystem, and deplete oxygen levels in the water, which can harm aquatic life.

6. **Conclusion**: Therefore, the correct answer to the question is that excessive amounts of chemicals in water bodies cause increased growth of **algae**.
