Nitrogen cycle
The transfer of nitrogen from the atmosphere to plants and back occurs through a process known as the nitrogen cycle. Nitrogen gas (N₂) in the atmosphere is converted into ammonia (NH₃) by nitrogen-fixing bacteria in soil or root nodules of certain plants, allowing plants to absorb it. Once consumed by animals and eventually decomposed, nitrogen returns to the soil as organic matter, where it can be further converted into nitrates and nitrites, or back into nitrogen gas through denitrification processes, completing the cycle. This cycle is crucial for maintaining soil fertility and supporting plant growth.
No, plants do not transfer nitrogen through respiration in the nitrogen cycle. Instead, they primarily take up nitrogen in the form of nitrates and ammonium from the soil, which they use for growth and metabolism. Respiration in plants mainly involves the release of carbon dioxide as they convert glucose and oxygen into energy. The nitrogen cycle includes processes like nitrogen fixation, nitrification, and denitrification, but respiration is not directly involved in the transfer of nitrogen.
Since 78.08% of the Earth's atmosphere is composed of nitrogen, yes. But it cannot be used in biological processes. The nitrogen animals use comes in the form of nitrogen compounds acquired from food. Ultimately, the nitrogen used by most living things is produced by nitrogen-fixing bacteria which do use nitrogen from the atmosphere, these compounds are then taken in and used by plants.
Plants that can use nitrogen from the atmosphere are known as nitrogen fixers. The legume or pea family of plants are famous for being able to do this.Most plants don't have this ability.
No, not all living things can absorb nitrogen directly from the atmosphere. Most organisms, including plants and animals, rely on nitrogen-fixing bacteria to convert atmospheric nitrogen into forms they can use, such as ammonia or nitrates. Certain plants, particularly legumes, have symbiotic relationships with these bacteria that enable them to access nitrogen. However, the majority of life forms must obtain nitrogen through the food chain or soil.

Although the atmosphere is rich in nitrogen gas, plants cannot use this form directly. Nitrogen needs to be converted into a usable form like nitrates by soil bacteria for plants to uptake. In cases where the soil lacks these nitrogen-fixing bacteria or has been depleted due to overfarming, there can be a shortage of available nitrogen for plants.

no plants and animals cannot use nitrogen straight out of the air every time we take a breath you breath it in but it goes through nitrogen fixation to let us humans animals and plants to use it.
Nitrogen gas (N2) in our atmosphere is an example of a form of nitrogen that humans cannot directly use. Additionally, nitrate (NO3-) in soils is not directly usable by humans and must first be converted by plants into a more bioavailable form of nitrogen.
NO. Nitrogen is a required nutrient for plants but it is obtained from ammonia or nitrates used as fertilizers. Some plants can "fix" (convert nitrogen in the air to an usable form) with the assistance of microorganisms living at the roots.
In rainforests where there is loads of leeching, plants get their nitrogen from other dead plants, where a nitrogen cycle is established
Nitrogen is transferred from the atmosphere to the soil through processes like nitrogen fixation by bacteria or lightning, where plants can uptake this nitrogen from the soil. Organisms then consume these plants, incorporating the nitrogen into their own tissues. When organisms die and decompose, nitrogen is released back into the soil, where it can be recycled back into the atmosphere as nitrogen gas through denitrification by bacteria, completing the nitrogen cycle.
