Where do plants get the carbon dioxide they need to survive?
A
from the ground
B
from the water
C
from the air
D
from other plants
Explanation: 

Detailed explanation-1: -Carbon dioxide is a gas found in the air; plants can take in this gas through tiny holes in their leaves. Once they have water and carbon dioxide, they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen.

Detailed explanation-2: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil.

Detailed explanation-3: -Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata. (One of these holes is called a stoma. The plural is stomata.

Detailed explanation-4: -The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun’s energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.

Detailed explanation-5: -Plants get carbon dioxide from the air through their leaves, and water from the ground through their roots. Light energy comes from the Sun.
