"And the oxygen in it helps with cellular respiration."
"This air that we breathe is so amazing."
"Imagine how it would be without the air to breathe."
"Without it, we wouldn't break down starch into sugars so we couldn't eat."
"That would be horrible!"
"I can't wait to eat this food and let cellular respiration break it down into energy."
"Yeah, it's a good thing our bodies can break down the energy that photosynthesis produces."
"That food was great but now I am stuffed."
"So am I, so let's let cellular respiration break down the food we just ate."
Title: The Human and The Cow
This comic helps to explain Cellular Respiration by showing that oxygen is needed and that it is the process in which food that is consumed is broken down (digested) and the energy is taken in. The waste then goes and is turned into feces.
