Remoras, or scker fish, attach themselves to sharks and travel with them. when the sharks feed, the remora detach themselves and feed on pieces of fish the sharks left behind. what two types of interactions are described in this scenario?
a.
predation and commensalism
b.
predation and mutualism
c.
competition and parasitism
d.
competition and commensalism

The right option is; a. Predation and commensalism

Predation is an interaction between organisms in which one organism (the predator) benefits from another organism (the prey), while commensalism is also an interaction between organisms of different species in which one species benefits from the other without either harming or benefiting the latter. From the question, the remoras benefits from the relationship by living on sharks and feeding on the leftovers of the sharks, but the sharks are not affected in any way. The relationship describes predation and commensalism.

B and E

Explanation:

Social behaviour is described as interactions taking place between two or more individuals with in the same species.

The interactions outside the species are not considered part of social behaviour.

Thus, out of all given options, option B and E are correct.

Option A, D and C , are not correct because with in animals itself there are millions of species and thus interaction with in the species is not considered as social behaviour.
