During rainy seasons, the ground becomes slippery due to dense growth of

Options

A. Moss
B. Brown Algae
C. Green Algae
D. Blue- Green Algae

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks why the ground becomes slippery during the rainy season. We need to identify the organism responsible for this phenomenon.

2. **Analyzing the Options**: The options provided are:
- Option 1: Moss
- Option 2: Brown algae
- Option 3: Green algae
- Option 4: Blue-green algae (Cyanobacteria)

3. **Identifying the Correct Organism**:
- Blue-green algae, also known as cyanobacteria, are known to thrive in moist conditions and can produce a gelatinous mass.
- This gelatinous mass is secreted by the blue-green algae and can cover the ground, making it slippery.

4. **Reasoning**:
- During the rainy season, the moisture in the environment promotes the growth of blue-green algae.
- The gelatinous substance they produce increases the surface area and creates a slippery layer on the ground.

5. **Conclusion**: Based on the analysis, the correct answer to the question is **blue-green algae** (Option 4). The other options (moss, brown algae, and green algae) do not produce this gelatinous mass and therefore do not contribute to the slippery ground.

**Final Answer**: Blue-green algae (Cyanobacteria) are responsible for making the ground slippery during the rainy season.
