Explanation:

1. Oxpeckers get food and zebras get pest - removal, so it's mutualism where both are helped.
2. Tapeworms benefit by stealing nutrients from the host animals, harming the hosts, which is parasitism.
3. Algae get a living place and spider - crabs get camouflage, a mutual benefit, so it's mutualism.
4. Remora fish benefit from the shark's food scraps and the shark is neither helped nor harmed, which is commensalism.
