Lesson Objectives...

• Engage in an argument from evidence that, in animals, oxygen reacts with carbon-containing molecules to provide energy and produce carbon dioxide and that organisms might have different structures that work together to do similar functions.

Investigating Other Organisms...

What we figured out this lesson...

• Animals, aside from humans, rearrange matter in food through chemical reactions to release energy.

• In animals, besides humans, oxygen reacts with food to produce carbon dioxide and provide energy.

• Animals might have different structures inside of their bodies to perform the same function.

• Other living things, such as anaerobic bacteria, don't need oxygen for chemical reactions to get energy.
