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.
What else can I help you with?
Is nitrogen important for plants and animals?
Yes.
Can humans get the nitrogen they need to exist in the air?
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.
What are 2 ways nitrogen becomes useable to plants animals and humans?
by Bacteria.
Can animals use nitrogen directly from the atmosphere?
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.
How do plants get nitrogen compared to how animals get nitrogen?
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.
Why is nitrogen fixation important to both plants and animals?
Nitrogen fixation is important because it converts atmospheric nitrogen into a form that plants can use to grow and thrive. This makes nitrogen available to animals through the consumption of plants that have been able to utilize fixed nitrogen. Ultimately, nitrogen fixation helps sustain the food chain and ecosystem health.
What is the source of nitrogen for animals?
Animals get nitrogen from 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.
Is photosynthesis is only vital to humans?
Photosynthesis is important to plants, animals, and humans! So no. It's most vital to plants.
What are two functions of plants and animals in the nitrogen?
plants and animals
What are two ways nitrogen becomes usable two plants humans and animals?
Amino acids, proteins and DNA.
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.
