Answer:
A. Plants
Explanation:
Nitrogen fixation is one of the processes involved in the NITROGEN CYCLE. It is the process whereby atmospheric nitrogen (N2) is converted into nitrogenous compounds such as ammonia, nitrates by certain nitrogen-fixing bacteria such as AZOTOBACTER.
The nitrogenous compounds which nitrogen fixation converts N2 into are in a form that PLANTS can use. Plants cannot utilize nitrogen gas, hence, the importance of this conversion into a form that plant can make use of.
Based on the traditional definition of species, bacterial species cannot be defined readily, due to the fact that they do not mate.
<h3>Why does the typical definition of a species not fit bacterial species?</h3>
The definition of species is that a species is one with distinct characteristics that produce viable offspring when mated with another organism in the same species.
This definition of a species does not fit bacterial species because bacterial species do not mate or reproduce se×ually.
Bacterial species reproduce by other means that do not involve mating such as by binary fission.
Therefore, based on the traditional definition of species, bacterial species cannot be defined readily, due to the fact that they do not mate.
