2. It is an example of commensalims
3. It is called sea anemone
4. It is called hermit crab
Answer codes :

Options

A. A and B are correct
B. B and C are correct
C. C and D are correct
D. A and D are correct

Answer

To solve the question regarding Adamsia, we need to analyze each statement provided about it:

1. **It is a parasite**: This statement is incorrect. Adamsia is not a parasite; it does not live off another organism in a harmful way. Instead, it has a mutualistic relationship with hermit crabs.

2. **It is an example of commensalism**: This statement is correct. Adamsia lives in association with hermit crabs, where it benefits from the crab's shell for protection and nutrients, while the crab is not significantly harmed or benefited by the presence of Adamsia.

3. **It is called sea anemone**: This statement is also correct. Adamsia is indeed a type of sea anemone, which belongs to the genus of sea anemones.

4. **It is called hermit crab**: This statement is incorrect. Adamsia is not a hermit crab; rather, it is a sea anemone that associates with hermit crabs.

Now, let's summarize the findings:

- Statements 2 and 3 are correct.
- Statements 1 and 4 are incorrect.

Thus, the answer code that corresponds to the correct statements is **b and c**.
