Is it true although 78 percent of air is nitrogen plants cannot use this form well?
It is very close to it, being about 78.09%.
Why are leguminous plants rich in protein?
Leguminous plants have nodules on their roots containing bacteria which can fix nitrogen contained in the air in the soil. This nitrogen becomes available to the plant, which uses the nitrogen as an essential part of the proteins of its cells. Other types of plant cannot do this, and have available only the nitrate which is already present in the water in the soil.

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.
What is the purpose of nitrogen-fixing bacteria?
Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle Updated by: Levi Levitt
How do humans get nitrogen we need to make proteins and dna if we can't get it from breathing?
Humans and most other living things are unable to use nitrogen from the atmosphere in their metabolism. The only living things able to use nitrogen from the atmosphere in their metabolism are a small number of species of anaerobic nitrogen fixing bacteria. Several species of nitrogen fixing bacteria are symbiotic with legume plants, the bacteria provide the legume with fixed nitrogen, the legume provides the bacteria isolation from the poisonous oxygen in the air as well as carbohydrates as food. Humans as all other animals, get their fixed nitrogen by eating other animals and/or plants.
What is the only form of nitrogen that nonlegume plants can take in and use?
photosynthesis

How do waste products help to grow plants?
That they are rich in nitrogen, which is an essential plant nutrient, is the reason why waste products can be used to help grow plants.Specifically, among the most effective waste products are those from such soil food web members are earthworms. Nitrogen tends to be readily present in the soil, but not often available to plants. It only is available for intake by plant roots if it is in soluble form. Soil food web members such as earthworms take in nitrogen, which is eliminated in soluble form due to processing inside the worm's body.
What are the different ways by which nitrogen in the air reaches the soil?
Lightning changes the nitrogen in the air into another form called nitrate.THE NITRATE IS BROUGHT DOWN TO THE SOIL BY RAIN.Nitrate is the only form of nitrogen that can be absorbed by plants through its roots.--hhahahah
Why cant plants absorb gaseous nitrogen?
plants and animals are not adapted to absorb nitrogen from the air. Nitrogen Fixation is a process where nitrogen is changed into a more reactive form for plants and animals to use. There are several ways where nitrogen fixation can happen: lightning, bacteria, carnivorous plants and industrial fixation.
Why can't animals use nitrogen in the air?
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
Why is it important for nitrogen to be recycled in an ecosystem?
Nitrogen is one of the elements present in nitrates which is a mineral that plants need for growth. Nitrogen fixing soil bacteria take the nitrogen from the air and change it into ammonium, and then further changed by nitrifying bacteria into nitrates. these nitrates are then taken up by the plants.
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.
Identify one plant which is rich in protein?
Leguminous plants are rich in protein for the following reason. Leguminous plants have nodules on their roots containing bacteria which can fix nitrogen contained in the air in the soil. This nitrogen becomes available to the plant, which uses the nitrogen as an essential part of the proteins of its cells. Other types of plant cannot do this, and have available only the nitrate which is already present in the water in the soil.
Does nitrogen form single bonds only?
No; nitrogen can form single, double, or triple bonds.
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.
