B. Excess nitrogen causes algal blooms.

C. Excess nitrogen causes plants to die.

D. Excess carbon causes algal blooms.

Answer: C. Excess nitrogen causes plants to die.

Explanation:

Nitrogen is the element which is commonly found in the fertilizers. It is the most important ingredient required for the growth of the plants. Nitrogen in excess amounts in the soil will lead to the loss of certain plant species. It may result in the depletion of the nutrients of the soil, increase in salt content of the soil which may cause dehydration in plants hence results in decline in the distribution of plants.
