Carbon cycle and Global warming

What is happening in step
1?

• Animals are decomposing and realizing carbon into the soil.
• Animals are releasing energy into the environment and storing carbon.
• Animals are turning carbon dioxide from the atmosphere into organic molecules.
• Animals are breaking down organic molecules and releasing carbon dioxide into the atmosphere.
