Question

which of these is an outcome of excess nitrogen in our soil? choose one option a acid rain b water deoxygenation c nutrient - depleted soil d all of the above

Explanation:

• Option A: Excess nitrogen can contribute to acid rain as nitrogen oxides (from nitrogen - related processes) in the atmosphere can form acidic compounds that fall as acid rain.
• Option B: Excess nitrogen in soil can lead to runoff into water bodies. This stimulates algal blooms, and when the algae die and decompose, oxygen in the water is consumed, leading to water deoxygenation (hypoxia).
• Option C: Excess nitrogen in soil can cause an imbalance in nutrient uptake by plants. It can lead to other nutrients like potassium, phosphorus, etc., being less available, resulting in nutrient - depleted soil over time as the soil's nutrient balance is disrupted.

Since all of the options (A, B, and C) are outcomes of excess nitrogen in soil, the correct option is D.

Answer:

D. All of the above
