What is the source of nitrogen in plants?
plants are ultimate source of food because it supports to live human being as well as animal.animals eat plants and we know that every living being contain nitrogen when an animals die their nutrients are being converted into simpler for by bacteria and bacteria dissolve this nutrients into soil and this nitrogen are used by plants again and this process continues on and thus we can say that plants are ultimate source of food
The plant source of Nitrogen is Nitrate. Plants acquire nitrate through the Nitrogen Cycle. Atmospheric Nitrogen is absorbed by Nitrogen-fixing bacteria. The bacteria produce Ammonia which becomes Nitrite. Nitrite becomes Nitrate, the usable form of Nitrogen for plants. Nitrate is assimilated and absorbed by plants. Plants produce amino acids and proteins that are consumed in the food chain. Whatever consumes the proteins and amino acids will eventually die and the decomposition produces ammonia which turns…
Your body is not capable of directly using the nitrogen in air. It is ultimately the source of the nitrogen in the proteins and other nitrogen-containing compounds in your body, but the precursors for these are (mostly) made by nitrogen-fixing bacteria in the soil and then incorporated into molecules by plants. (The "mostly" is because some of the nitrogen used by plants comes from nitrates or ammonia applied as fertilizer.)
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…
Nitrogen compounds have more than one source in nature. Nitrogen fixing bacteria, found in the root nodules of leguminous plants, are a major source. Lightning produces a certain amount of nitric oxide (through combustion of oxygen and nitrogen in the atmosphere) which dissolves in the rain to form nitric acid, which also contributes biologically usable nitrogen.
Yes, a venus fly trap does perform photosynthesis and it does fix CO2. It consumes insects largely as a source of nitrogen. Most plants get nitrogen from the soil - this is the reason we fertilize our crops and apply "plant food" to houseplants. But venus fly traps live in places where the soils are very poor in nitrogen. The insects give them a supplemental nitrogen source.
