Verified step by step guidance1
Understand the nitrogen cycle: The nitrogen cycle is a series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.
Identify the role of ammonia: Ammonia is a key compound in the nitrogen cycle, often produced by the decomposition of organic matter and used by plants as a nutrient.
Consider the major reservoirs: In the nitrogen cycle, major reservoirs for nitrogen compounds include the atmosphere, soil, oceans, and living organisms such as plants.
Evaluate each option: Determine which of the given options (soil, oceans, plants, atmosphere) is a significant reservoir for ammonia based on its role in the nitrogen cycle.
Conclude based on the nitrogen cycle: Soil is a major reservoir for ammonia as it contains organic matter that decomposes to release ammonia, which can be used by plants or further processed by soil bacteria.
