How fertilizers increase soil fertility?
As we all know that nitrogen is esential for plants which is not directly taken by plants,so in industries nitrogen is collected which is convert into crystal like formation.We feel cold if we take some fertilisers in our hand and deep it in water as the nitrogen is very cool gas.
Do animals take in nitrogen directly from the atmosphere?
Since 78.08% of the Earth's atmosphere is composed of nitrogen, yes. But it cannot be used in biological processes. The nitrogen animals use comes in the form of nitrogen compounds acquired from food. Ultimately, the nitrogen used by most living things is produced by nitrogen-fixing bacteria which do use nitrogen from the atmosphere, these compounds are then taken in and used by plants.
What do plants do with the nitrogen they take in?
they don't take in nitrogen
What is nitrogen like?
Nitrogen is light weight and visible to see. It can make ice by putting water into a glass full of nitrogen and wait for about 4-5 minutes and take it out with a pair of tweezers. And you have ice!
Why is too much nitrogen harmful to your water supply?
It pollutes organisms, and does not dilute well. When the fist "take in the air-full of nitrogen" they pass on the an overload of nitrogen, unknowingly to the next generation of fish.
How an organism interacts directly with a living Element in the aquarium?
The plants take in carbon dioxide given off by the fish during the day
Do most organisms take in nitrogen from the air or water and use it to carry out their process life?
yes!
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.
Can liquid nitrogen be used as a fertilizer for agriculture?
No. Firstly liquid nitrogen has a boiling point of 77K. That's -196degrees Celsius, which will freeze all water in contact with it. Not only will the roots not be able to take up water from the soil, water within the plant cells will also freeze, damaging the roots. Secondly, liquid nitrogen will vaporize rapidly when exposed to the environment, which is at room temperature. This means that when liquid nitrogen is poured into the soil, it is not different from the plant absorbing nitrogen in the form of gaseous nitrogen. Thirdly, nitrogen uptake is best facilitated in the aqueous form, ie. dissolved in water in the form of nitrate or ammonium ions. Liquid nitrogen/gaseous nitrogen do not dissolve very well in water.
How does a plant take in nitrogen?
plants take in nitrogen compounds through their roots.
How do plants take nitrogen from the atmosphere?
Plants absorb nitrate compounds from soil through their root hairs, which are outgrowths of the trichoblast cells in the roots.Most plants are not able to use nitrogen as such (N2), though some, including legumes and casuarinas, supply water and food to symbiotic nitrogen-fixing bacteria in specialised root nodules, and these fix nitrogen to nitrate which they supply to the plants.
How do plants get the nitrogen they need?
From the soil by the roots or fixation from the air
