Carbon and Nitrogen are recycled between living and non-living things.
I practiced the cards for at least 3 minutes.

Imagine the nitrogen cycle is like a big adventure for nitrogen atoms. They start out in the air as something called "nitrogen gas," which is like a bunch of nitrogen atoms holding hands really tightly.
Now, plants and animals, like us, need nitrogen to grow big and strong. But, they can't use the nitrogen gas in the air because it's all locked up in a tight group. So, the nitrogen atoms need to go through a process called assimilation.
Assimilation is like a magical transformation! Some special bacteria and plants work together to change the nitrogen gas into a form that plants can use. It's like turning a big, tough puzzle piece into a small, easy one that can fit into a plant's puzzle.
Once the plants have these usable nitrogen pieces, they can use them to grow leaves, stems, and even fruits. Then, when animals eat those plants, they get the nitrogen too! It's like passing along the magic of growth from plants to animals.
So, assimilation is like the superhero power that turns tough nitrogen gas into a form that plants and animals can use to grow big and healthy!
What does assimilation do in the nitrogen cycle?
