How do plants get the carbon dioxide they need for photosynthesis?

• Carbon dioxide is produced in a chemical reaction inside their chloroplasts.

• Carbon dioxide enters their leaves from the atmosphere.

• Carbon dioxide enters their roots from the soil.

• Carbon dioxide is produced in a chemical reaction inside their mitochondria.

What do plants do with most of the oxygen produced in photosynthesis?

• They use most of the oxygen to make more glucose.

• They release most of the oxygen into the atmosphere.

• They release most of the oxygen into the soil.

• They use most of the oxygen to produce carbon dioxide.

Why is photosynthesis important to plants?

• It prevents the buildup of too much water in their cells.

• It produces the carbon dioxide they need for plant digestion.

• It breaks down a simple sugar into a type of energy their cells can use.

• It produces a simple sugar they need for cellular respiration.

Photosynthesis is important to animals because

• oxygen, which animals breathe, is released as a byproduct.

• carbon dioxide, which animals need for cellular respiration, is released as a byproduct.

• it prevents any of the sun's energy from being absorbed by animals' skin.

• it prevents carbon dioxide from destroying animals's habitats.
