, Q) How do plants take in nitrogen?
There is a bacteria known as RHYZOBIUM which are present in
the plant’s roots which changes gaseous nitrogen into a usable
form for plants
Carbon dioxide is produced by humans and animals and its
released by Green plants
If we burn fuels the CO2 level in the atmosphere gets disturbed
Oxygen is produced by Green plants and released by humans
and animals
If we cut trees the oxygen level in the atmosphere gets
disturbed
