26. P (parasitism) - The tick benefits by feeding on the blood of the dog, while the dog is harmed by the presence of the tick.
27. C (commensalism) - The bird benefits by having a place to build its nest, while the tree is not affected.
28. M (mutualism) - Both the bees and the flower benefit from this relationship. The bees get nectar for food, while the flower gets pollinated.
29. C (commensalism) - The hermit crab benefits by finding a new shell, while the snails are not affected as they are already dead.
30. M (mutualism) - Both the ants and the acacia tree benefit from this relationship. The ants protect the tree from herbivores, while the tree provides food and shelter for the ants.
31. C (commensalism) - The egret benefits by feeding on the insects stirred up by the grazing cattle, while the cattle are not affected.
32. M (mutualism) - Both the fungus and algae benefit from this relationship. The fungus provides a suitable environment for the algae to grow, while the algae provide food for the fungus through photosynthesis.
33. P (parasitism) - The tapeworm benefits by feeding on the nutrients in the cow's intestines, while the cow is harmed by the presence of the tapeworm.
34. M (mutualism) - Both the honey guide bird and the honey badger benefit from this relationship. The bird leads the badger to the bees hive, where both can consume honey for food.
Put the letter (M for mutualism, C for commensalism, P for parasitism) which describes the type of symbiosis in numbers 26-34. Make sure you understand the characteristics of predation and competition as well!
