Which of the following statements about eutrophication is TRUE? A. Eutrophic bodies of water are characterized by clear water that is relatively free of algae.
B. Climate change will not affect eutrophication because phytoplankton growth is unrelated to temperature.
C. Eutrophication is typically driven by natural processes like rock weathering and nitrogen fixation.
D. Eutrophication is sometimes associated with compounds that are hazardous to human health.

C. It is driven by natural processes like rock weathering and nitrogen fixation.

Explanation:

It has been discovered that eutrophication occurs through a gradual increase in the deposition of phosphorus and nitrogen and other plants nutrients in the water bodies.

This will allow the maximum growth of algae on the surface of the water.

It has been discovered that eutrophication is not good for the water bodies. This is because, the excess growth of algae on the surface of the water will prevent the sunlight from penetrating the water, thereby preventing the plants inside the water from making use of the sunlight to carryout photosynthesis. Also, it will prevent oxygen from entering, thereby depriving the organisms in the water from having the necessary oxygen needed for respiration.

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
