A sudden increase in the amount of available nutrients can create
problems for an aquatic
ecosystem. How?

B. Increased nutrients can cause producers to
compete aggressively with one another.

C. There is not enough oxygen in the

aquatic plants.

C

Explanation:

There would be a high amount of nitrates and phosphates, which reduces the amoubt of oxygeb in the tank, that will lead to the difficulty of supportibg the excessive amount of aquatic plants.

C. There is not enough oxygen in the

atmosphere to support excessive numbers of

aquatic plants.

Explanation:

n excess amounts, both nutrients can cause an increase in aquatic plant growth and algae blooms, called eutrophication. These algae blooms live at the water surface, in order to easily access oxygen and sunlight. As a result, eutrophication prevents lower water levels from access to sunlight and oxygen in the air.
