The carbon and nitrogen cycles are closely linked in our environment, and they play a big role in supporting life.

1. Carbon Cycle:

   • Plants take in carbon dioxide (CO2) from the air when they make their food in a process called photosynthesis.
   • Animals then eat these plants and take in carbon, which becomes part of their bodies.

2. Nitrogen Cycle:

   • Special bacteria help change nitrogen from the air into forms that plants can use.
   • Animals get nitrogen by eating these plants.

3. Connection Between Carbon and Nitrogen:

   • When plants and animals die, decomposers break them down.
   • This process puts carbon and nitrogen back into the soil, making it rich for new plants to grow.

By learning about these cycles, we can see just how important they are for keeping life going on Earth!
