Nitrate is the most common form of nitrogen useful to plants, but they can also use ammonium nitrogen and organic nitrogen.
Plants and animals die and decomposers break down their nitrogen containing molecules to ammonia. All animals get the nitrogen they need by eating plants, by eating other animals that ate plants, or by eating animals that ate animals that ate plants.
Nitrogen is obtained by the plants in the mineral form.
Nitrogen is found in all living systems as part of the makeup of biological compounds. Animals obtain the nitrogen they need by eating plants, or by eating other animals that have eaten plants.
The atmospheric nitrogen. This is a diatomic and triple bonded form of nitrogen that can not be metabolized by organisms other than some bacteria which convert it into usable form for plants.
Nitrogen is needed for all life forms, including plants. Plants absorb nitrogen from soil through their roots in the form of nitrate and ammonia.
Nitrogen must be in the compound form before it is used by plants or animals
Nitrogen is everywhere But somehow, nitrogen has to get from the atmosphere into a form that our body can use.I also think that nitrogen in soil can be used by plants not animals
Plants and animals die and decomposers break down their nitrogen containing molecules to ammonia. All animals get the nitrogen they need by eating plants, by eating other animals that ate plants, or by eating animals that ate animals that ate plants.
Nitrogen fixing bacteria will enable some plants to convert atmospheric oxygen to a form that can be used by plants. The plants are then eaten by animals.
Fixation
Nitrogen is present in amino acids which form proteins. All plants and animals need nitrogen for growth.
Nitrogen is obtained by the plants in the mineral form.
Nitrogen is found in all living systems as part of the makeup of biological compounds. Animals obtain the nitrogen they need by eating plants, or by eating other animals that have eaten plants.
Because the nitrogen in the air is in a form not usable to animals and plants. The only way animals get nitrogen to build protein and nucleic acid is by eating it. This is usually through plants, which get there nitrogen from the soil. They get it from the soil cuz bacteria in the soil turn the atmospheric nitrogen into a usable form. In a water ecosystem cyanobacteria a.k.a. blue-green algae transform the nitrogen from the atmosphere into usable forms of nitrate
The atmospheric nitrogen. This is a diatomic and triple bonded form of nitrogen that can not be metabolized by organisms other than some bacteria which convert it into usable form for plants.
The nitrogen cycle is how nitrogen moves between plants, animals, bacteria, the atmosphere, and the soil. In each phase, it is in a different form.
Plants do not actually get their nitrogen from the atmosphere. They get it in compounds in the soil through their roots. Some plants form symbiotic relationships with bacteria in the soil. The bacteria draw nitrogen from the air and form nitrogen compounds. The plants can then use the nitrogen.
