NITROGEN CYCLE

Nitrogen changes so it can be used by plants.

Nitrogen          Ammonia

Ammonia         Nitrite

Nitrite               Nitrate

Plants take

in nitrate.

There is a lot of nitrogen in the air.  78% of our air is nitrogen.

Nitrogen has to get down into the soil so plants can use it.

But, plants don't take

in ammonia.

Bacteria change ammonia

into nitrite.

Bacteria change nitrite

into nitrate.

SOMETIMES NITRATE IS NOT USED BY PLANTS.

THE PROCESS IS REVERSED.

NITROGEN GOES BACK INTO THE AIR.

Nitrate is changed into nitrite.

Next, nitrite is changed

into ammonia.

Then ammonia is changed

into nitrogen.

Nitrogen is a source of nourishment from food. Nitrogen moves in the nitrogen cycle.

Plants need nitrogen. But air nitrogen can't get in.

Bacteria to the rescue!
