Kristine exercises regularly. The process of cellular respiration makes it possible for Kristine to run on the treadmill and to lift weights. What do her cells do during cellular respiration?

• Convert kinetic energy into chemical energy

• Absorb light energy through the chlorophyll in their chloroplasts

• Combine water and carbon dioxide to produce oxygen and glucose

• Break down food molecules to release energy in the form of ATP

There is a relationship between breathing and cellular respiration. Breathing involves taking in oxygen and releasing carbon dioxide. How does the oxygen affect the process of cellular respiration?

• Oxygen and ATP combine to produce energy in the form of carbon dioxide.

• Oxygen and glucose combine to produce energy in the form of ATP molecules

• Oxygen and hydrogen combine to produce energy in the form of ATP molecules.

• Oxygen and carbon dioxide combine to produce energy in the form of ATP molecules.

Carbon exists in many forms on Earth. The diagram below shows part of the carbon cycle.

Based on evidence in the diagram, what is happening in Step 1?

• Animals are releasing energy into the environment and storing carbon.

• Animals are decomposing and releasing carbon into the soil.

• Animals are converting carbon dioxide from the atmosphere to oxygen.

• Animals are breaking down organic molecules and releasing carbon dioxide into the atmosphere.
