Every time you breathe…

Every time you breathe… you take in this much Nitrogen…

But plants can’t use this kind of Nitrogen Every time you breathe… you take in this much Nitrogen… and this much Oxygen… But plants can’t use this kind of Nitrogen

First, lightning and some types of bacteria that live on plant roots create nitrogen compounds that plants can use. The Nitrogen Cycle

Plants absorb nitrogen compounds through their roots, and use it to build cells.

First, lightning and some types of bacteria that live on plant roots create nitrogen compounds that plants can use. The Nitrogen Cycle

Moo

Animals eat the plants. Their waste puts Nitrogen back into the ground. Which makes the plants grow stronger…

The Nitrogen Cycle Summary First, lightning and some types of bacteria that live on plant roots create nitrogen compounds that plants can use. The Nitrogen Cycle Summary Nitrogen is transferred between plants and animals repeatedly…endlessly.
