Answer 1

Answer:

Parasitism, predation, and commensalism, all three are common as only one species is benefited in process.

Answer 2

Symbiosis is the ecological relationship between two or more organisms living closely together with some form of feeding relationship involved. The three main symbiotic relationships are: - Mutualism, where both organisms benefit. - Commensalism, where one organism benefits while the other organism is not harmed. All of them thrive off of the other organism.
