Neighborhoods in coastal areas use algaecide in their ponds to control algae growth. The algaecide interferes with the algae's ability to conduct photosynthesis which kills the algae, allowing the pond to look clean. When there is a large rainstorm, the algaecide runs off into the local area streams. This water eventually runs out into the ocean. What is the likely outcome of the algaecide getting into the oceanic ecosystem?

• Increase in the size of the fish

• Increase in the number of zooplankton

• Plants will increase in size

• Plants will decrease in number
