Question

_____ is used by plants as nnitrates.​

Answer 1

Answer:

Plants absorb nitrogen from the soil both in the form of nitrate ammonium (NH4+). Some species of plant prefer NO3 than NH4 because plant easily convert NO3 to Protein and Amino acid then NH4. Nitrate is readily absorbed by plant root and not need any further conversion, Nitrate is the form of nitrogen most used by plants for growth and development. Ammonium taken in by plants is used directly in proteins.

Answer 2

Answer:

Nitrogen

Explanation:

Plants use nitrogen in the form of nitrates, which is nitrogen mixed with oxygen. They usually absorb nitrates from the soil.

The bacterium RhiZobium living in the root nodules of leguminous plants ( eg: pea plant) converts atmospheric nitrogen into nitrates (soluble form) do that the plants can use it. Nitrogen fixation also takes placing during lightning.
