Question

which happens to a body of water if there is too much nitrogen present?
a. there is a decrease in turbidity.

b. there is an increase in dissolved oxygen.

c. there is an increase of algal growth.

d. there is an increase in animal and plant diversity.

Explanation:

Nitrogen is a nutrient. Excess nitrogen in water leads to eutrophication. Algae thrive on nutrients like nitrogen. As algae grow rapidly (algal bloom), it affects water quality. Turbidity (cloudiness) increases due to algae, not decreases. Algal decomposition consumes dissolved oxygen, reducing it. Algal blooms create harsh conditions (e.g., low oxygen when algae die and decompose), which decrease animal and plant diversity, not increase it.

Answer:

C. There is an increase of algal growth.
