20
Q
People need ___________ . Plants make___________
A
Oxygen
21
Q
Why is water important?
Your Answer:
A
Water is important because we depend on it for our survival; all living things need it. We consume water when eating and drinking, and plants need water for growth.
22
Q
Why is carbon important?
Your Answer:
A
Carbon is important because if we did not have it, all the plants would die, which means no oxygen.
