Question

nitrogen fixation can occur biotically through bacteria or abiotically through non - living processes. which abiotic process can fix atmospheric nitrogen (n₂) into usable forms? decomposers eating organic matter and decomposing it large lightning strikes splitting atmospheric n₂ humans growing agricultural crops with a lot of irrigation consumers digesting food that they have eaten to digest it

Explanation:

Abiotic nitrogen fixation relies on non-living processes. Lightning strikes generate high heat that breaks the strong triple bond in atmospheric $\text{N}_2$, allowing it to react with oxygen and water to form usable nitrogen compounds. The other options involve living organisms (biotic processes) or unrelated human activities.

Answer:

B. large lightning strikes splitting atmospheric $\text{N}_2$
