Why do all organisms require nitrogen?
All living organisms require nitrogen to grow. All organisms require nitrogen to make amino, acids, which in turn are used to build proteins.
What happens to the nitrogen compounds that are not absorb by the plants?
A number microbes in the soil, water and air transform these nitrogen compounds
What is the cycle involving the exchange of nitrogen between organisms and the atmosphere?
nitrogen cycle
Which organisms are most critical in the nitrogen cycle?
Bacteria is the organism most critical in the nitrogen cycle. Bacteria in the nitrogen cycle provides different forms of nitrogen compounds used by higher organisms.
Which organisms captures atmospheric nitrogen for the process of nitrogen fixation?
Legumes. They are the primary plant in an ecosystem, and help convert atmospheric nitrogen in nitrogen in the soil that plants can absorb through their root systems. The process is called nitrogen fixation.The organisms involved in nitrogen fixation are nitrifying bacteria like Azatobacter and Pseudomonas forming root nodules in legumenous plants.
What is organisms that can be transform unusable nitrogen in the atmosphere into chemical compounds containing nitrogen that can be used by other organisms?
Nitrogen-fixing bacteria
What is the large reservoir of nitrogen that is unusable by most organisms?
The air is 80% nitrogen but most organisms are able to extract it from the air.
Bacteria are the only organisms that can be what?
Transform atmospheric nitrogen into ammonia.
Which organisms transform nitrogen to a form that is useful to plants?
bactieria
What is atmospheric nitrogen fixationand how does it affect organisms?
The atmosphere is made up of 70% nitrogen. Nitrogen is also a key ingredient for proteins and nucleic acids such as DNA, and without these, no life could exist. However, the nitrogen in the atmosphere is unusable for most organisms. A few types of microorganisms are capable of fixing nitrogen into a bioavailable form, and that is the process of nitrogen fixation. The fixed nitrogen can then be used by plants to create amino acids, and the amino acids are then consumed by animals.
How does nitrogen fixation make nitrogen available to organisms?
Nitrogen gas composes 70% of the atmosphere but because it is so stable it remains a gas and unusable to plant. Bacteria have evolved that can break the N2 bond and provide nitrogen as a soluble product to the roots of plants. Once taken up by the plant the nitrogen moves through the food chain to animals etc.
How does atmospheric nitrogen fixation affect organisms?
Atmospheric nitrogen fixation is the process where nitrogen is converted into ammonia. Without nitrogen, organisms couldn't grow, and organisms need nitrogen more than anything to grow.
What are blue green algae that lives at the root of azolla plant?
Blue green algae or cyanobateria are nitrogen fixing prokaryotic bacteria which are one of the few organisms which can turn atmospheric ,comparitively inert and unusable nitrogen(N2)into usable compounds like nitrites(NO2) and nitrates(NO3)which are used by plants for synthesis of nitrogen compounds like proteins necessary for life
Why do all organisms require nitrogen?
All living organisms require nitrogen to grow. All organisms require nitrogen to make amino, acids, which in turn are used to build proteins.
What organisms transform light energy from the sun into food for other organisms in an ecosystem?
si
How do colonies of cyanobacteria benefit aquatic organisms?
Colonies of cyanobacteria benefit aquatic organisms because they can be an important source of food to organisms.Daily random word from ClarrissaBlooms : Smile
What organisms are capable of converting gaseous nitrogen in the air into a form that other living organisms can use?
Nitrogen-fixing bacteria
