The correct Answer is:
To analyze the assertion and reason provided in the question, we can break down the information step by step: ### Step 1: Understand the Assertion The assertion states that the relationship between a sea anemone and a hermit crab is an example of obligate mutualism. - **Explanation**: In obligate mutualism, both species involved are dependent on each other for survival. This means that one or both species cannot live without the other. ### Step 2: Analyze the Relationship In the case of the sea anemone and hermit crab, the sea anemone provides protection to the hermit crab from predators, while the hermit crab provides food for the sea anemone. - **Explanation**: The sea anemone attaches itself to the shell of the hermit crab. The hermit crab benefits from the protection offered by the stinging tentacles of the sea anemone, while the sea anemone benefits from the scraps of food that the hermit crab leaves behind. ### Step 3: Determine if it is Obligate Mutualism The relationship between the sea anemone and the hermit crab is not strictly obligate mutualism; it is more accurately described as proto-cooperation. In proto-cooperation, both species benefit, but they can survive independently of each other. - **Explanation**: While both species benefit, they do not have to rely on each other for survival. For example, hermit crabs can exist without sea anemones, and sea anemones can survive without hermit crabs. ### Step 4: Understand the Reason The reason states that obligate mutualism is a positive interaction between two species. - **Explanation**: This statement is true. Obligate mutualism indeed refers to a beneficial interaction where both species are positively affected. ### Conclusion The assertion is false because the relationship between the sea anemone and hermit crab is not an example of obligate mutualism; it is proto-cooperation. The reason is true as it correctly describes obligate mutualism. ### Final Answer - **Assertion**: False - **Reason**: True
