Why do plants need nitrogen?
All plants need nitrogen to make amino acids, proteins and DNA, but the nitrogen in the atmosphere is not in a form that they can use. Other plants get the nitrogen they need from the soils or water in which they live mostly in the form of inorganic nitrate (NO3-). Bacteria living in plant nodules in the soil on the roots of the plant also provide the plant with the nitrogen it needs while providing the bacteria a sugar source. Nitrogen is a limiting factor for plant growth.
How does nitrogen from the air get into the bodies of plants and animals?
When the animals breathe in nitrogen it goes into their bodies so when they die and decompose the nitrogen they breathed in is now in the soil and also when they fertilize on the land.
Which bacteria live in soil and fix nitrogen as part of the nitrogen cycle?
Leguminous plants contain symbiotic bacteria called Rhizobia within nodules root systems, producing nitrogen compounds that help the plant to grow and compete with other plants. When the plant dies, the fixed nitrogen is released, making it available to other plants and this helps to fertilise the soil.
Why is nitrogen important for plants?
All plants and animals need nitrogen to make amino acids, proteins and DNA, but the nitrogen in the atmosphere is not in a form that they can use. The molecules of nitrogen in the atmosphere can become usable for living things when they are broken apart during lightning strikes or fires, by certain types of bacteria, or by bacteria associated with legume plants. Other plants get the nitrogen they need from the soils or water in which they live mostly in the form of inorganic nitrate (NO3-). Nitrogen is a limiting factor for plant growth.
What lives in the roots of leguminous plants and convert atmospheric nitrogen into plants unable form?
Rhizoobium or nitrogen fixing bacteria lives in the roots of leguminous plants.leguminous plants are not able to use atmospheric nitrogen as sush,so these bacteria convert nitrogen into simpler forms i.e nitrates and nitrits which are easily used up by these plants.
What type of plants does nitrogen live on?
Nitrogen is an element and does not live on anything...

Venus fly traps are plants that eat animals. Why are not these consumers like animals?
They still make their own food but they do require nitrogen and the soils that they live in don't provide enough.
Why are desert soils so low in organic matter?
Soils get their organic material from the plants that live, or have lived, in them. Deserts have few plants to provide this material.
Is the most nitrogen fixation performed by plants?
It is performed by nitrogen fixing bacteria that live on the roots of plants.
In the nitrogen cycle bacteria that live on the roots of plants.?
change nitrogen gas into ammonia
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.
Why do animals need nitrigen to live?
Animals and plants need nitrogen to live because proteins and other biological compounds contain nitrogen. In plants, nitrogen compounds perform photosynthesis. In humans, nitrogen is the basis for amino acids, the building blocks of genetic material.
In the nitrogen cycle bacteria that live on the roots of plants?
change nitrogen gas into ammonia
What does a plant use nitrogen for?
At www.fernlea.com, it says "This nutrient is responsible for the healthy green color of your plants. It is an essential part of proteins and chlorophyll, the plant pigment that plays a vital role in photosynthesis. Nitrogen deficiencies result in a yellowing of leaves, and a general slow down in growth."
How does nitrogen fixation work in the process of converting atmospheric nitrogen into a form that plants can use for growth?
Nitrogen fixation is the process of converting atmospheric nitrogen into a form that plants can use for growth. This is done by certain bacteria, like Rhizobium, that live in the roots of leguminous plants. These bacteria have the enzyme nitrogenase, which converts atmospheric nitrogen into ammonia, a form of nitrogen that plants can absorb and use for their growth.
How does nitrogen from the air get into the bodies of plants and animals?
When the animals breathe in nitrogen it goes into their bodies so when they die and decompose the nitrogen they breathed in is now in the soil and also when they fertilize on the land.
