Verified step by step guidance1
Understand that the nitrogen cycle is a biogeochemical process that transforms nitrogen into various chemical forms, making it accessible to living organisms.
Recognize that nitrogen gas (N₂) in the atmosphere is not directly usable by most plants and animals. It needs to be converted into compounds like ammonia (NH₃), nitrate (NO₃⁻), or nitrite (NO₂⁻).
Identify the key processes in the nitrogen cycle: nitrogen fixation, nitrification, assimilation, ammonification, and denitrification.
Nitrogen fixation is the process where nitrogen gas is converted into ammonia by bacteria or through industrial processes, making it available for plants.
Conclude that the primary purpose of the nitrogen cycle in organic chemistry is to convert nitrogen gas into forms that can be used by plants and animals, supporting their growth and survival.
