1. Identify the ecological roles of the fish and the shark. 2. Identify the type of symbiosis that exists with these two organisms. Explain the
reason for your choice.
3. Identify a second type of symbiosis and what would have to change in their
relationship to be that type of symbiosis.

Sharks acts as predators whereas fish act as prey.

Explanation:

Sharks acts as predators that play an important role in the ecosystem by controlling the population many marine animals from causing damaged to the ecosystem whereas fish is considered as the primary consumers that provides food to the secondary consumers and helps to maintain balance in the ecosystem. Mutualism, predation and commensalism are the types of symbiosis that present between fish and shark. Remoras fish feed on the parasites present on the shark's skin and in its mouth which benefits the shark as well as the fish whereas in commensalism,  the pilot fish takes benefit from the shark but there is no known effect on the shark.
