In the early 1900s, oyster fishermen cut sea stars (starfish), which are predators of oysters, into pieces and threw them back into the sea. This practice led to an explosion in a. other sea stars ate the pieces and were able to increase their reproductive output. b. each arm with a portion of the central disc regenerated into a new individual. c. competition was removed from the stronger sea stars that were not caught, increase their reproductive output. d. the oyster population grew due to this new food supply, allowing the population of their predators to increase. e. each arm could form a new individual through budding.
