What are two reasons humans can not live without plants?

The Benefits of Plants

• We can breathe!

• Plants give us oxygen

• We can eat!

• Plants give us food and they give our food food (moo)

The relationship between plants and animals

• Trees take in carbon dioxide

• Trees release oxygen

• Animals breathe in oxygen

• Animals breathe out carbon dioxide.

Where does the carbon come from?

If we breathe IN oxygen but we breathe OUT carbon dioxide... Where does the carbon come from?

Multiple Choice

Where does the carbon that we breathe out come from?

• CO2 (carbon dioxide)

• C6H12O6 (carbohydrates)

• CH4 (Methane)

• O2 (Oxygen)

Where does the carbon come from?

• The CO2 that we breathe OUT comes from the Carbohydrates that we EAT!

• C6H12O6 + O2 -> CO2 +Energy

Cellular Respiration

• Plants STORE their "energy" from the sun in the form of carbohydrates.

• Humans and animals eat those carbohydrates and we use it as "energy" to fuel our bodies.

Multiple Choice

Where does a human's energy come from?

• The air

• The sun

• The food we eat

• The soil

Cellular Respiration

• As we chew, swallow and digest our food we get nutrients and energy

• The stomach and small intestines break down starch into simple sugars.

• Those simple sugars give us energy!

Cellular Respiration

• Those simple sugars are taken in by our cells.

• The mitochondira of the cell breaks down the sugars and releases carbon dioxide and energy (ATP)

Multiple Choice

What does the mitochondria break down to make energy for our bodies?

• Carbon dioxide

• Carbohydrates (sugars)

• Oxygen

• Water
