Question

Which of the following best describes the transfer of fecal coliform and an impact on the environment?

Fecal coliform increases the growth of algae in surface water bodies, killing fish.
Digestive problems in humans are elevated from the increase of fecal coliform into drinking water.
Fecal coliform decreases the amount of dissolved oxygen and an overpopulation of fish in surface water bodies occurs.
Fecal coliform increases the amount of organic substances in water and lowers the amount of dissolved oxygen, killing fish.​

Answer 1

Oxygen bodyworkers origins of substations in water and lowers in the amount of dissolve the oxygen killing fish but it’s all gonna be OK because the carbon dioxide equals to killing fish drinking water so you don’t have a C stroke

Answer 2

Fecal coliform increases the amount of organic substances in water and lowers the amount of dissolved oxygen, killing fish.​

Step-by-step explanation:

Fecal coliform are species of bacteria that are found in the intestine of warm-blooded animals like humans etc. Hence, they are released whenever they excrete feaces. Due to this reason, the presence of fecal coliform bacteria in a water body indicates fecal discharge into that water.

The presence of excessive fecal coliform in a water body increases the amount of organic substances in the water. These organic substances are decomposed by bacteria, which causes the oxygen present in the water body (dissolved oxygen) to deplete/decrease. The depletion of oxygen in the water threatens aerobic aquatic organisms e.g fishes and they ultimately suffocate and die.
