Positive effects of aquaculture include all of the following except a. creating a consistent food supply b. changing natural marine life habitats c. providing marine life for aquariums d. controlling the types of marine life grown

The appropriate answer is b. changing natural marine life habitats. Any unnatural change in any ecosystem can have negative implications for marine organisms as each organism is dependent on the other.
Aquaculture is beneficial as it creates a consistent food supply for the world's growing population and takes the pressure off natural marine life. Aquaculture creates marine life for aquariums and prevents the act of removing natural marine life from their habitat.
