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.
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.
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.
What is the diffrence between fixed nitrogen and free nitrogen?
OK well free nitrogen is fixed by bacteria that live in the soil. some bacteria live in nodules, or bumps , on certain plant roots. the bacteria get food from the plants, and plants absorb fixed nitrogen from the bacteria. animals get nitrogen by eating plants or by eating prey that have eaten plants. fixed nitrogen may enter the soil in other ways too. a small amount of free nitrogen in the air by lighting. it is carried to the ground by rainfall. fixed nitrogen also enters the soil because of decomposers. decomposers break down dead organisms, and fixed nitrogen is released in the soil. the fixed nitrogen can be absorbed by plant roots.
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.

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.
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."
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.

How do animal commonly get nitrogen?
Through ingestion. Plants associate with thingies that live in the soil and give them nitrogen, that nitrogen goes up the food chain.
