Explanation:

1. Oxpeckers and zebras: Both organisms benefit. Oxpeckers get food, and zebras get pest - removal. This is mutualism.
2. Tapeworms and animals: Tapeworms benefit by getting food from the host, while the host is harmed as it loses nutrients. This is parasitism.
3. Spider crabs and algae: Both organisms benefit. Algae get a living place, and crabs get camouflage. This is mutualism.
4. Remora and shark: Remora benefits by getting scraps, and the shark is neither helped nor harmed. This is commensalism.
