Camouflage helps you organisms to blend with their surrounding so that they can escape predators. Which of the following is an example of camouflage ?

Options

A. Biston betularia moths of England
B. Darwin finches of Galapagos
C. Bacteria growing on penicillin medium
D. Lichens growing on trunk of tree

Answer

To determine which of the given options is an example of camouflage, we need to understand what camouflage is and how it functions in the animal kingdom. Camouflage is a survival mechanism that allows organisms to blend in with their environment, making it difficult for predators to spot them.

### Step-by-Step Solution:

1. **Understand the Concept of Camouflage**:
- Camouflage is a technique that allows organisms to avoid detection by predators. This is usually achieved by matching the color, pattern, and texture of their surroundings.

2. **Analyze the Options**:
- We need to evaluate each option provided in the question to see if it demonstrates camouflage.

3. **Option 1: Biston Betularia (Peppered Moth)**:
- The Peppered Moth is known for its ability to change its coloration based on its environment. In industrial areas, the moths became darker to blend in with soot-covered trees, thus avoiding predation. This is a clear example of camouflage.

4. **Option 2: Darwin Finches of Galapagos**:
- Darwin Finches do not change their color to blend in with their surroundings. They are known for their beak variations, not for camouflage. Therefore, this option does not represent camouflage.

5. **Option 3: Bacteria Growing on Penicillium Medium**:
- Bacteria do not exhibit camouflage as they do not change their color or appearance to blend in with their surroundings. This option is not an example of camouflage.

6. **Option 4: Lichens Growing on Trunk of Tree**:
- Lichens may have colors that can blend with tree trunks, but they do not actively change their color to avoid predators. They are not an example of camouflage in the same sense as animals.

7. **Conclusion**:
- After analyzing all the options, the only clear example of camouflage is **Option 1: Biston Betularia (Peppered Moth)**.

### Final Answer:
The correct example of camouflage is **Option 1: Biston Betularia (Peppered Moth)**.
