Answer 1

B) I would choose company 1 because they reduce nitrate and phosphate fertilizers the most.

Step-by-step explanation:

Dead zones begin to form when excess nutrients such as phosphorus and nitrogen enter coastal waters and help the growth of an organism called cyanobacteria, or blue-green algae. With too much nutrients the algae takes up most of the oxygen in the water, leaving other organisms with less oxygen, killing them. Fertilizers would be the main reason for a dead zone to form. Therefore, Company 1 would be the most suitable as they reduced the concentration of fertilizers in the water the most.
