Nitrogen Cycle Diagrams

Help yourself to learn the nitrogen cycle using these free and printable cycle diagrams! These nitrogen cycle diagrams are designed to guide you in studying the cycle of nitrogen. All living things need nitrogen, including your body. Most plants get the nitrogen they need from soil. In this post, we will explain to you about the cycle of nitrogen alongside the illustrations drawn on the diagrams.

The nitrogen cycle diagram is a model that explains how nitrogen is recycled. Through these cycle diagrams, the process of the cycle is explained. Five main processes cycle nitrogen through the biosphere, atmosphere, and geosphere: nitrogen fixation, nitrogen uptake through organismal growth, nitrogen mineralization through decay, nitrification, and denitrification. Nitrogen gas is converted to nitrate compounds by nitrogen-fixing bacteria in soil or root nodules. Lightning also converts nitrogen gas to nitrate compounds. The Haber process converts nitrogen gas into ammonia used in fertilizers. Ammonia is converted to nitrates by nitrifying bacteria in the soil.

Plants then absorb nitrates from the soil and use these to build up proteins. The plant may be eaten by an animal, and its biomass used to produce animal protein. Urea and egested material is broken down by decomposers. This results in nitrogen being returned to the soil as ammonia. Decomposers also break down the bodies of dead organisms resulting in nitrogen being returned to the soil as ammonia. Higher only: In some conditions denitrifying bacteria in the soil break down nitrates and return nitrogen to the air. This is usually in waterlogged soil. Improving drainage reduces this effect, making the soil more fertile.
