The park grounds keepers recently applied high nitrogen fertilizer to the grass surrounding the lake. This caused leeching of the nitrogen into the lake which initially caused a rapid increase in cyanobacteria growth and eventually to the algae bloom. The algae bloom then died, causing decomposing bacteria to flourish and deplete the dissolved oxygen content of the water, thereby leading to the fish die-off. The increase in dinoflagellate population has caused a high concentration of toxins in the water to build up resulting in the fish dying. The increase in cyanobacteria growth caused algae to die and release toxins that killed the fish. Fertilizer applied around the lake by grounds keepers caused the algae bloom. The algae bloom decreased the dissolved oxygen level in the water resulting in the fish dying and increasing the cyanobacteria population.

![You are an environmental microbiologist working for the county health department. Large numbers of fish have been dying in a lake located in one of the
county parks. You have been assigned to investigate the cause of the fish die off. After sampling the water you observe a high number of the below
pictured organism present. Which of the following best explains the cause of the fish dying?
