By lightening and by nitrogen fixing bacteria in the roots of certain plants (eg the legumes).
The nutrient that cycles through organisms, rivers, rain, and the atmosphere is nitrogen. This nitrogen cycle involves processes such as nitrogen fixation, where atmospheric nitrogen is converted into usable forms by bacteria, and denitrification, which returns nitrogen to the atmosphere. Additionally, nitrogen is transported through water bodies and is taken up by plants and animals, highlighting its integral role in ecosystem functioning.
Yes. Lightening can fix nitrogen from the atmosphere into the soil, making nitrogen available to the plants and ultimately animals in an ecosystem.
Free nitrogen refers to the nitrogen gas (N2) present in the atmosphere, which is not readily available for use by most organisms. Fixed nitrogen, however, is nitrogen that has been converted into a form that can be utilized by plants and other organisms, such as ammonia, nitrate, or nitrite. This conversion process is often carried out by nitrogen-fixing bacteria in the soil.
No, the nitrogen cycle has an atmospheric component. Nitrogen gas (N2) in the atmosphere is converted into compounds that can be used by living organisms through processes like nitrogen fixation and denitrification. This atmospheric nitrogen is essential for the functioning of the nitrogen cycle on Earth.
The nutrient that organisms tend to get from their local ecosystem is phosphorus. They can also get the nutrient nitrogen locally.
Lightning & a few bacteria.
Nitrogen fixation is the process by which nitrogen gas from the atmosphere is converted into ammonia by certain bacteria. Ammonification, on the other hand, is the process by which organic nitrogen from dead organisms or waste is converted into ammonia by decomposers like bacteria and fungi. Nitrogen fixation introduces new nitrogen into the ecosystem, while ammonification recycles existing nitrogen.

Conversion of Nitrogen gas into Nitrates\Ammonia.-When Lightning strikes the nitrogen in air get converted into Nitrogen Oxides and then is brought down by rain in from of Soluble Nitrates.These Nitrates are the soluble form of nitrogen for plants. Though lightning play a minor role in nitrogen fixation.-Nitrogen is also fixed by Microorganisms which are free-living or the organisms that live in the plants (Symbiotic relations).These Organisms convert the nitrogen in soluble nitrates.-Nitrogenous Fertilizers are also one from of Soluble nitrogen.*** These Nitrates and ammonia fertilizers are then consumed by plants and the plants are consumed by us.Hence Nitrogen is in the Biotic Part of the Ecosystem.
The largest amount of nitrogen in an ecosystem is typically found in the atmosphere, where it makes up about 78% of the air we breathe. Nitrogen is also present in living organisms and in the soil, where it plays a crucial role in the nitrogen cycle.

When nitrogen dies, it does not go anywhere because it is an element. However, when nitrogen-containing organisms die, the nitrogen in their bodies gets recycled in the ecosystem through decomposition by bacteria and other organisms. This releases nitrogen back into the environment to be used by other living organisms.
Nitrogen originates from the atmosphere and is converted into usable forms by bacteria in the soil. It is essential for plant growth and plays a crucial role in the overall ecosystem dynamics by influencing plant productivity, nutrient cycling, and biodiversity.
nitrogen fixing is a process in which atmosphere nitrogen converted into ammonia.
