Identify the correct match w.r.t population .

Options

A. Goats and Abingdon tortoise -amensalism
B. Sea anemone and hermit crab-commensalism
C. Cuckoo and crow-Brood parasitism
D. Chlorella and Hydra -proto-cooperation

Answer

To solve the question of identifying the correct match with respect to population interactions, we will analyze each option provided in the question step-by-step.

### Step-by-Step Solution:

1. **Understanding the Types of Interactions**:
- **Commensalism**: One species benefits while the other is neither helped nor harmed.
- **Mutualism**: Both species benefit from the interaction.
- **Parasitism**: One species benefits at the expense of the other.
- **Competition**: Two species compete for the same resources, which can be harmful to one or both.
- **Brood Parasitism**: A specific form of parasitism where one bird lays its eggs in the nest of another bird.

2. **Analyzing the First Option: Goats and Abandoned Tortoise (Emensalism)**:
- Emensalism is when one species is harmed. However, this interaction is more accurately described as competition, as the introduction of goats led to the extinction of the tortoise due to higher grazing activity.
- **Conclusion**: This is **not** a correct match.

3. **Analyzing the Second Option: Sea Anemone and Hermit Crab (Commensalism)**:
- Commensalism typically involves a relationship like that between clownfish and sea anemones. The sea anemone does not benefit from the hermit crab, and this relationship is not well-defined as commensalism.
- **Conclusion**: This is also **not** a correct match.

4. **Analyzing the Third Option: Cuckoo and Crow (Brood Parasitism)**:
- This is a classic example of brood parasitism, where the cuckoo lays its eggs in the crow's nest, benefiting from the crow's parental care while the crow is harmed by raising a chick that is not its own.
- **Conclusion**: This is a **correct match**.

5. **Analyzing the Fourth Option: Chlorella and Hydra (Protocooperation)**:
- Protocooperation implies mutual benefit without dependency. However, Chlorella and Hydra have a mutualistic relationship where both organisms benefit from each other, which is not accurately described as protocooperation.
- **Conclusion**: This is **not** a correct match.

### Final Answer:
The correct match with respect to population interactions is **Cuckoo and Crow (Brood Parasitism)**.
