Plantae.
Any nitrogen-fixing bacteria adds nitrogen to the soil for plants. More than 90 percent of all nitrogen fixation is effected by these organisms and they play an important role in the nitrogen cycle. There are a few plants that love nitrogen gas. They are able to draw the nitrogen gas from the air and store it in their roots. These are called nitrogen fixing plants. But they need help from the bacteria mentioned above. They do release a little nitrogen to the soil and when they die, they add more. The group of plants that do this are the legumes (peas and beans).
Diazotroph is the common name for nitrogen-fixing bacteria and micro-organisms.Specifically, the term designates organisms that are capable of turning atmospheric nitrogen into more usable forms, such as ammonia. It includes such soil-dwellers as Frankia genus members living symbiotically with actinorhizal (beech, cucurbit and rose-related orders) plants and Rhizobia genus members living symbiotically with leguminous (bean-related order) plants. Cyanobacteria living symbiotically with lichens and liverworts also number among the diazotrophs of greater name recognition.
Animal
phosphorus
A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring
Species
Organisms that can interbreed are all members of the same species if their offspring are viable (can themselves breed).
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.
A fundamental category of taxonomic classification, ranking below a genus or subgenus and consisting of related organisms capable of interbreeding.
the group number for nitrogen is group 15.
The nitrogen group is group 15 on the periodic table.
No. Nitrogen is in group 15 not in group 17.
