B)increased need for sulfur
C)decreased need for carbon
D)death of most members of any ecosystem

Question

Quizplus · Accepted Answer

When the biological oxygen demand (BOD) is high, it means that there are high levels of organic matter in the water that bacteria will consume with the help of oxygen. As more organic matter is added to the water, more bacteria will grow, and they will consume more and more oxygen in the water. When the available oxygen is depleted, the water becomes anaerobic. In such conditions, most members of any ecosystem cannot survive, and they eventually die. The oxygen-deprived water becomes a breeding ground for bacteria that thrive in anaerobic environments, resulting in the release of gases such as methane and hydrogen sulfide, which further contributes to water pollution.
