How do plants and animals differ in the ways they obtain nitrogen?
Plants get it from bacteria which live associated with their roots who take atmospheric nitrogen and fixate it (nitrogen cycle). Animals can only get it by ingesting organic compounds which contain nitrogen, such as plants and other animals which have eaten plants.
What type of organism is able to covert free nitrogen from the atmosphere to form that is usable for animals?
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.
How do rhizobacteria help plants?
Plants can not use atmospheric nitrogen. Rhizobacteria fixes atmospheric nitrogen into nitrate.plant can utilize nitrate in their metabolism.thus fertility of the soil is maintained.
How do plants get nitrogen compared to how animals get nitrogen?
Most plants get nitrogen from fertilizers. Some plants can have a process called nitrogen fixing in which nitrogen from the is turned into ammonium compounds. Animals get their nitrogen from food, by eating plants and other animals.
Which is not a pathway by which plants obtain atmospheric nitrogen?
D
What are two ways that nitrogen is fixed so plants can use it?
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.
What is the source of nitrogen for animals?
Animals get nitrogen from plants.
Plant and animals can not use the nitrogen that makes up?
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.
Can humans get the nitrogen they need to exist in the air?
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.
What do bacteria do in nitrogen fixation?
Bacteria convert atmospheric nitrogen into a nitrogen-containing ion that plants can absorb.
How atmospheric nitrogen enters the soil?
Typically, atmospheric nitrogen gets into the soil by nitrogen-fixing bacteria that are symbiotic with such plants as clover, soybeans and alfalfa. Bacteria in the plant extract nitrogen from the air, and when the plants die, the nitrogen remains in the soil as the plant decays.
How do plants get atmospheric nitrogen?
some plants have bacteria in their roots which contain nitrogen when plants want nitrogen they exchange their food made them with nitrogen. Example: pea plants contain bacteria called rhizobium which contains nitrogen
