Omg please help ASAP Atmospheric nitrogen has to be combined with other elements, or fixed, in order to be used by plants. Lightning is one way that nitrogen is fixed. When lightning occurs, the extreme heat breaks the bonds in nitrogen molecules, allowing nitrogen to combine with oxygen and form nitrogen oxides. In what way is most of the nitrogen fixed by lightning made available for use by plants?

a
It is moved by the wind toward dry areas.
b
It is incorporated into the exoskeletons of flying insects that eat plants.
c
It is inhaled and exhaled by birds roosting in trees during rainstorms.
d
It is carried by rain to the soil.
