In the context of organ systems, what are chelipeds primarily used for?

• A. Feeding and defense
• B. Reproduction
• C. Respiration
• D. Locomotion

Answer: (A)

Verified step by step guidance

1. Begin by identifying what chelipeds are. Chelipeds are the large claws or pincers found on crustaceans such as crabs and lobsters.
2. Understand the primary functions of chelipeds. They are typically used for grasping and manipulating objects, which is crucial for feeding.
3. Consider the role of chelipeds in defense. These structures can be used to fend off predators or rivals, providing protection to the organism.
4. Evaluate the other options provided: reproduction, respiration, and locomotion. Determine if chelipeds are directly involved in these processes.
5. Conclude that chelipeds are primarily used for feeding and defense, as they are not directly involved in reproduction, respiration, or locomotion.
