Question

1. nitrogen is essential for life, but atmospheric nitrogen must be converted by bacteria into usable forms for plants. if a bactericide (a substance that kills bacteria) is added to the soil, what would most likely happen? plants would absorb nitrogen more quickly due to increased availability in the soil. nitrogen - fixing and nitrifying bacteria would die, disrupting nitrogen conversion for plants. nitrogen gas would be physically blocked from entering the soil through precipitation. decomposers would break down nitrogen faster, increasing nutrient levels for plants.

Explanation:

Nitrogen - fixing and nitrifying bacteria convert atmospheric nitrogen for plants. Bactericide would kill them, disrupting this process.

Answer:

B. Nitrogen - fixing and nitrifying bacteria would die, disrupting nitrogen conversion for plants.
