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 solve the question regarding which option is an example of camouflage, we will analyze the options provided and determine which one fits the definition of camouflage.

### Step-by-Step Solution:

1. **Understanding Camouflage**:
- Camouflage is a survival adaptation that allows an organism to blend in with its environment to avoid detection by predators.

2. **Evaluating the Options**:
- **Option 1: Byzantine Battleria moths of England**:
- Historical context: Before industrialization, the tree bark was covered with white lichens, making the light-colored moths less visible to predators. After industrialization, the dark soot-covered bark favored the dark-colored moths, allowing them to blend in and avoid predation.
- Conclusion: This is a clear example of camouflage as the moths adapted their visibility based on their environment.

- **Option 2: Darwin finches of Galapagos**:
- These finches are known for their beak variations, which are adaptations to their feeding habits, not camouflage.
- Conclusion: This does not represent camouflage.

- **Option 3: Bacteria growing on penicillium medium**:
- Bacteria do not use camouflage; they are affected by the medium they grow in and do not blend into their environment.
- Conclusion: This does not represent camouflage.

- **Option 4: Lichens growing on the trunk of the tree**:
- Lichens are not organisms that camouflage themselves; they are stationary and do not have a predatory relationship.
- Conclusion: This does not represent camouflage.

3. **Final Decision**:
- After evaluating all options, the only example of camouflage is **Option 1: Byzantine Battleria moths of England**.

### Answer:
The correct answer is **Option 1: Byzantine Battleria moths of England**.
