Plants obtain the carbon used in the manufacture of organic compounds from ____
A
carbon dioxide in the atmosphere
B
organic compounds in the soil
C
organic compounds in the soil
D
ammonia in the soil
Explanation: 

Detailed explanation-1: -Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.

Detailed explanation-2: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

Detailed explanation-3: -carbon fixation. the process by which photosynthetic organisms such as plants and algae turn inorganic carbon compounds (usually carbon dioxide) into organic carbon compounds (usually carbohydrate sugars such as glucose).

Detailed explanation-4: -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.
