Explanation:

1. The buffalo - mosquito - egret relationship is mutualism as egrets benefit from mosquitoes stirred up by buffalo and buffalo are unaffected.
2. Hummingbirds and flowers have a mutualism relationship as hummingbirds get nectar and flowers get pollinated.
3. Eagle and bear competing for salmon is competition.
4. Intestinal bacteria and humans have a mutualism relationship as bacteria get nutrients and produce vitamin K for humans.
5. Sticklebacks and tapeworm is parasitism as tapeworm harms sticklebacks.
6. Aphids and plants is parasitism as aphids remove nutrients from plants.
7. Mite and people using mascara is commensalism as mite feeds on mascara without harming people.
8. Coyote and rabbit is predation as coyote hunts and eats rabbit.
9. Yucca flowers and yucca moths have mutualism as moths pollinate flowers and larvae spread seeds.
10. Tick and dog is parasitism as tick feeds on dog's blood harming it.
11. Sea anemone and clownfish have mutualism as they both benefit from each other.
12. Barnacles and whales is commensalism as barnacles benefit and whales are not affected.
13. Ostriches and gazelles have mutualism as they both benefit by watching for predators.
14. Hermit crabs and shells is commensalism as shells are inanimate and hermit crabs benefit by using them.
