Two major ways whereby nitrogen is fixed in ecosystems are through rainfall and through leguminous crops.
Nitrogen-fixing bacteria help cycle nitrogen through the ecosystems in a variety of ways. With plants, the nitrogen-fixing bacteria help ensure that nitrogen is cycled back into the soil.
OK well free nitrogen is fixed by bacteria that live in the soil. some bacteria live in nodules, or bumps , on certain plant roots. the bacteria get food from the plants, and plants absorb fixed nitrogen from the bacteria. animals get nitrogen by eating plants or by eating prey that have eaten plants. fixed nitrogen may enter the soil in other ways too. a small amount of free nitrogen in the air by lighting. it is carried to the ground by rainfall. fixed nitrogen also enters the soil because of decomposers. decomposers break down dead organisms, and fixed nitrogen is released in the soil. the fixed nitrogen can be absorbed by plant roots.
The short answer is yes. I am not sure about the amount but there are only two ways nature converts N2 into a form of nitrogen that is usable by plants. The two ways are microorganisms and lightning. I believe bacteria are the main nitrogen fixers, but there might also be some algae that convert nitrogen as well. We have also mastered fixing N2, the process is the Haber- Bosh process.
Ecosystems can be altered through habitat destruction, introduction of invasive species, and pollution. These factors can disrupt the delicate balance of an ecosystem, leading to changes in species composition and overall ecosystem function.
Ecosystems with many connected food chains are known as complex or diverse ecosystems. These ecosystems have a variety of species interacting with each other in intricate ways, resulting in multiple food chains and a high level of biodiversity. Examples include tropical rainforests and coral reefs.
Why does atmospheric nitrogen need to be converted?
Nitrogen can be fixed through biological nitrogen fixation by nitrogen-fixing bacteria, through industrial processes like the Haber-Bosch process, and through lightning in the atmosphere which converts nitrogen gas into nitrogen compounds that can be used by plants.
Nitrogen can be fixed by lightning during thunderstorms, by industrial processes like the Haber-Bosch method, and through biological processes carried out by nitrogen-fixing bacteria in the soil.
Nitrogen can be fixed by lightning during thunderstorms, a process that converts nitrogen gas (N2) into nitrates (NO3-) that can be used by plants. Nitrogen can also be fixed by certain soil bacteria called nitrogen-fixing bacteria, which convert N2 into a form that can be taken up by plants.
Competition, symbiosis, and predation

The only forms of nitrogen compounds that living things can make use of are ammonia compounds and nitrate compounds.These are called "fixed nitrogen". Animals obtain the nitrogen they need from proteins in the plants and/or animals they eat. Proteins are amino acid polymers and amino acids are built around an ammonia group.
Nitrogen fixation in nature occurs through biological processes by symbiotic bacteria in plant roots, free-living soil bacteria, and certain types of blue-green algae in water bodies. Additionally, nitrogen can also be fixed through non-biological processes like lightning and industrial processes.
Nitrogen fixation is the process by which nitrogen gas in the atmosphere is converted into nitrogen compounds that plants can use. This can occur through biological nitrogen fixation, where certain bacteria convert nitrogen gas into ammonia, and through abiotic processes like lightning strikes, which convert nitrogen gas into nitrogen oxides that can be absorbed by rain and deposited in the soil.
Humans impact the nitrogen cycle by making fertilizers and burning fossil fuels, which alter the amount of fixed nitrogen our ecosystems.
Nitrogen is changed into ammonia through a process called nitrogen fixation, typically carried out by soil bacteria or certain plants like legumes. Ammonia is then converted into other forms of nitrogen such as nitrites and nitrates that are taken up by plants for growth and utilized by other living organisms in the food chain.
