True. Organisms typically utilize nitrogen in fixed forms, such as ammonia (NH3), nitrate (NO3-), or other nitrogen compounds, rather than as gaseous nitrogen (N2). This is because most organisms cannot directly use atmospheric nitrogen gas without it being converted or "fixed" by certain bacteria or through industrial processes.
True or False: Organisms deal better with nitrogen when it is not a gas, but when it is fixed into another nitrogen compound.
