Answer 1

Mutualism is characterized as an interaction that results in positive effects between individuals of various species. Commensalism is a long-term biological relationship where advantages are obtained by members of one species. Parasitism is a relationship between organisms within the body of the organism where one organism lives. One organism kills and eats another during predation.

Complete answer:
Mutualism is characterized as an interaction that results in positive effects between individuals of various species. hermit crab and sea anemone represent mutualism. In which hermit crab gets defence and sea anemone travels from place to place, crab and sea anemone display mutualism.
Echeneis (suckerfish) and shark demonstrate commensalism. Suckerfish has a dorsal fin modified by a sucker or holdfast. It connects to the shark's underside and thus remains covered. When the shark feeds on its prey, the fish gets its food from tiny bits left over.
Cuscuta is an angiosperm, which on Cissus and other plants is the complete stem parasite. Parasitism, like predation, is a type of interaction between consumers and resources.
Tigers are natural deer hunters and killdeer to feed on them.

The correct response, therefore, is option B.

Note:
The commensal relationship is always between a larger host and a smaller commensal; the host organism is unchanged, while the commensal organisms can be more structurally modified and compliant with their behaviours, as in remorse that travels attached to sharks and other fishes. In ecology, mutualism plays a key role. Mutualistic interactions, for example, are important for the function of the terrestrial ecosystem, as more than forty eight per cent of land plants depend on mycorrhizal interactions with fungi to provide them with fungi with inorganic compounds and microelements.
