2: Mutualism (+,+) | a relationship between two species of organisms in which both benefit from the association. | A pilot fish and a shark are an example of mutualism. The pilot fish cleans the shark and the pilot fish is protected by the shark.
3: The photo above represents bees receiving pollen from a flower. Both organisms benefit because the flower is being pollinated while the bee is getting food. | The sea anemones give protection to the crab using its stinging cells. Also it remoulds its shell to fit the crab while the crab allows the sea anemones to consume the remains of its food, thus it also provides the sea anemones with food supply, which makes it a relationship beneficial to both.
4: Commensalism (+,o) | A symbiotic relationship in which one organism benefits while the other is neither benefited nor harmed. | Clownfish and sea anemones are an example of commensalism because the clownfish shelters among the tentacles of the sea anemone, and the sea anemone is not affected.
5: Cattle egrets and cattle are an example of commensalism because the cattle egrets benefit because they manage to get the insects that they wish to prey on, also get protection from the cattle, whereas the cattle remains unaffected. | Barnacles and whales are an example of commensalism because the barnacles get a free ride on the whale, while the whale is not benefited nor harmed by the barnacles.
6: Parasitism (+,-) | The relation between two different kinds of organisms in which one receives benefits from the other by causing harm to it. | The tapeworm steals nutrients from the dog and the dog doesn't benefit because it has less nutrients and causes pain to it.
7: Lice are blood-feeding ectoparasites. Their bites cause intense itching in the human scalp where they feed on blood and have a place to reproduce. The human does not benefit because the lice are feeding off of their blood and causes irritation. | Female mosquitoes ingest blood for the protein. Male mosquitoes ingest plant juices. This benefits the mosquito because it gets food, but harm the human because it is taking blood, and it eventually ends up being a mosquito bits that irritates the skin.
