• C. Sucker fish and shark
• D. Vanda and tree

Answer 1

Answer:

B. Sea anemone and hermit crab

• The term mutualism can be simply defined as a relationship in which both species are mutually benefited.

• This relationship can either be within the species or between the two different species.

• The species with this relationship is termed as symbionts.

• The anemone protects its host from predators and shell crushing crabs by its stinging cells.

• The crab provides the anemone with a hard substrate and increased access to oxygenated water and food and in some cases with protection from predators.
