"Red tide" is the common name for an event that can occur in the coastal waters off the Florida peninsula. Runoff from over-fertilized farmland
reaches the ocean, allowing a type of algae to reproduce rapidly. This turns
the water a reddish color. The algae are usually toxic to native fish and
shellfish. Which best describes the effect of this change in habitat on the
organisms in the area? *

A Excess nutrient runoff is beneficial to all the organisms in the area.

B Excess nutrient runoff is harmful to the algae and beneficial to the fish.

C Excess nutrient runoff is harmful to all the organisms in the area.
