1 \u2013 Carbon dioxide , or CO2 , is a gas composed of one carbon and two oxygen atoms.<\/p>\n\n\n\n
2 \u2013 Carbon dioxide makes up about 0.037 percent of the air.<\/p>\n\n\n\n
3 \u2013 Slight as that amount is , plants and animals depend upon it for life. It is a very important component of Earth\u2019s atmosphere.<\/p>\n\n\n\n
4 \u2013 It plays an important role as a greenhouse gas. A greenhouse gas traps energy from the Sun , which warms Earth\u2019s surface. This is known as the greenhouse effect. Without the greenhouse effect , Earth would be much too cold for life.<\/p>\n\n\n\n
5 \u2013 Plants make their nutrients with it. They combine the carbon dioxide with water to make sugar by the process called photosynthesis . From the sugar , the plants then make starch and cellulose.<\/p>\n\n\n\n
6 \u2013 Plants absorb Carbon dioxide and emit oxygen as a waste product.<\/p>\n\n\n\n
7 \u2013 Animals eat the plants and in getting energy from the food , they produce carbon dioxide and return it to the air as they breathe.<\/p>\n\n\n\n
8 \u2013 Humans and animals breathe oxygen and emit Carbon dioxide as a waste product.<\/p>\n\n\n\n
9 \u2013 Plants remove carbon dioxide from the atmosphere by photosynthesis.<\/p>\n\n\n\n
10 \u2013 Carbon dioxide that goes into the atmosphere does not stay there but is continually recycled by plant.<\/p>\n\n\n\n
11 \u2013 Carbon dioxide is a nutrient , not a pollutant , and all life , plants and animals alike benefit from it.<\/p>\n\n\n\n
12 \u2013 Carbon dioxide is soluble in water , it occurs naturally in groundwater , rivers and lakes , in ice caps and glaciers and also in seawater.<\/p>\n\n\n\n
13 \u2013 It is present in deposits of petroleum and natural gas.<\/p>\n\n\n\n
14 \u2013 It is a food additive and acidity regulator in the food industry.<\/p>\n\n\n\n
15 \u2013 It is used to produce carbonated Soft drink and Soda.<\/p>\n\n\n\n
16 \u2013 Carbon dioxide is useful in baking as well. Yeast , baking powder and baking soda all release carbon dioxide gas when they are mixed into batter or dough. The gas forms bubbles , which cause the batter or dough to rise, or expand.<\/p>\n\n\n\n
