Do most organisms take in nitrogen from the air or water and use it to carry out their process life?
Most organisms take in nitrogen from the soil in the form of nitrates and ammonia, which are produced by nitrogen-fixing bacteria. These bacteria convert nitrogen gas from the air into usable forms. Some aquatic organisms can also directly uptake nitrogen from water in the form of nitrate, nitrite, or ammonia.
How do water plants obtain nitrogen if it is insoluble in water?
Marine ecosystems: Nitrogen is fixed in the photic zone by cyanobacteria who acquire it from the atmosphere (it isn't completely insoluble). The fixed Nitrogen can enter the water as Ammonia or Urea (which is soluble) and rains down to the deeper parts of the Ocean as detritus. Large Brown and Green algae, sea grasses and other plants of the ocean acquire Nitrogen from the Ammonia or Urea dissolved in the water, while organisms in the lower zones of the Ocean can filter feed Nitrogen from the detritus (these organisms are a part of the Nitrogen cycle, but are not plants obviously). Otherwise, algae typically grow to have a significant part of their bodies reach the surface, where they can fix Nitrogen directly. Aquatic: Either from ammonia released by bacteria, from bacteria living in the anaerobic 'soil' beneath the water or by growing to the surface and directly fixing the Nitrogen there.

Do animals take in nitrogen directly from the atmosphere?
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.
Do producers take in energy from nitrogen?
No, producers do not directly take in energy from nitrogen. They obtain energy through the process of photosynthesis, where they convert sunlight into chemical energy stored in glucose. Nitrogen is necessary for the synthesis of proteins and nucleic acids in plants, which are essential for growth and development.
What is the transfer of nitrogen from air to soil to organism?
Nitrogen gas in the air is converted into usable forms by soil bacteria through a process called nitrogen fixation. Plants then take up these forms of nitrogen from the soil. When organisms consume plants, they obtain nitrogen from the plants, and the nitrogen cycles through the food chain as organisms are consumed by other organisms.
Can liquid nitrogen be used as a fertilizer for agriculture?
No. Firstly liquid nitrogen has a boiling point of 77K. That's -196degrees Celsius, which will freeze all water in contact with it. Not only will the roots not be able to take up water from the soil, water within the plant cells will also freeze, damaging the roots. Secondly, liquid nitrogen will vaporize rapidly when exposed to the environment, which is at room temperature. This means that when liquid nitrogen is poured into the soil, it is not different from the plant absorbing nitrogen in the form of gaseous nitrogen. Thirdly, nitrogen uptake is best facilitated in the aqueous form, ie. dissolved in water in the form of nitrate or ammonium ions. Liquid nitrogen/gaseous nitrogen do not dissolve very well in water.
Does plants take in nitrogen directly from air?
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.
How does nitrogen get out of soil?
Nitrogen can leave the soil through processes such as denitrification, leaching, and plant uptake. Denitrification converts nitrates in the soil into nitrogen gas, which then escapes into the atmosphere. Leaching involves nitrogen moving with water through the soil and eventually reaching groundwater or surface water. Plants take up nitrogen from the soil to use for growth and development.
What is nitrogen like?
Nitrogen is light weight and visible to see. It can make ice by putting water into a glass full of nitrogen and wait for about 4-5 minutes and take it out with a pair of tweezers. And you have ice!
How an organism interacts directly with a living Element in the aquarium?
The plants take in carbon dioxide given off by the fish during the day
How do consumers obtain nitrogen?
Consumers obtain nitrogen through the food they eat, as nitrogen is an essential component of proteins. Inorganic nitrogen can also be found in the air we breathe, but our bodies cannot use this form directly.
Can animals use nitrogen directly from the atmosphere?
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.
