All living things need nitrogen - it is a key part of both plant and animal tissue, and plants wouldn't be able to grow without it. We get our nitrogen by eating protein, but most plants have to get it from the soil. Garden plants use up a lot of nitrogen, so it needs to be replaced with fertilizer or you won't be able to keep growing plants on the same plot of land.
In nature, some plants are able to pull nitrogen out of the air which helps replenish the soil, and when old plants die and rot the nitrogen returns to the ground. This doesn't happen in a garden if the plants are eaten for food or thrown away when they die.
nitrogen is needed by all living things and is one of the main ingredients of fertilizers. understanding what happens to it helps one fertilize more efficiently and create less pollution.
helps plant growth.. look up the nitrogen cycle
Plants and animals die and decomposers break down their nitrogen containing molecules to ammonia. All animals get the nitrogen they need by eating plants, by eating other animals that ate plants, or by eating animals that ate animals that ate plants.
Yes.
by Bacteria.
no plants and animals cannot use nitrogen straight out of the air every time we take a breath you breath it in but it goes through nitrogen fixation to let us humans animals and plants to use it.
Most plants get nitrogen from fertilizers. Some plants can have a process called nitrogen fixing in which nitrogen from the is turned into ammonium compounds. Animals get their nitrogen from food, by eating plants and other animals.
Animals get nitrogen from plants.
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.
Photosynthesis is important to plants, animals, and humans! So no. It's most vital to plants.
plants and animals
A lot of comes from the air. The air you breathe is around 78 percent nitrogen, so nitrogen enters your body with every breath. Rhizobium bacteria is present in leguminous plants in their roots which extract nitrogen from the soil. These are generally present in dicot-seed plants. When you consume these plants, nitrogen enters your body. Another way that nitrogen enters the body is through eating meat. When animals eat plants, those plants have nitrate in them which contains nitrogen so the animals have nitrogen in them now. Then, humans eat the meat from the animals, adding some nitrogen to our bodies.
Photosynthesis is important for humans because it provides oxygen for us.
Amino acids, proteins and DNA.
