Question
Abiotic natural means of nitrogen fixation occurs through: a. thunderstorm b. nitrogen fixing bacteria c. ammonification d. Haber's process
Correct Answer
Option A is the correct answer.
Detailed Explanation
Lightning (thunderstorms) provides a high-energy abiotic (non-living) means of nitrogen fixation. The energy breaks nitrogen molecules apart, allowing them to combine with oxygen to form nitrogen oxides, which dissolve in rain to form nitrates that reach the soil.
Hint
This natural event provides the energy to split nitrogen gas.
