Suppose we removed whelks from the intertidal community. Predict the effect (increase, decrease, no change) on the population sizes for each of the following species. It is important to consider indirect effects. For each of the small gray arrows, you can consider that effect negligible and treat it as a neutral (0) effect. coral weed sea stars + acorn barnacles mussels gooseneck barnacles nori seaweed + chiton mussel ochre sea star nori seaweed [Choose ] [Choose ] [Choose ] [Choose ] [Choose ] acorn barnacle black pine gooseneck barnacle
