Q

What happens in each stage of respiration?

A

1st Stage
Sugar is broken down into smaller molecules
Oxygen is not involved
Small amount of energy is released
2nd Stage
Small molecules are broken down into smaller molecules
Oxygen is required
Large amount of oxygen is released

Q

What is the opposite of respiration? Why?

A

Photosynthesis because the raw materials and products are switched to begin and to end

17
Q

What is fermentation

A

Oxygen not nescassary

18
Q

What happens on Earth if all the plants die?

A

We would die

19
Q

Where does water and carbon dioxide come from?

A

Water-roots when it rains
Carbon dioxide- Us when we breathe

20
Q

Name two things sugar is used for?
