Using sunlight, the plants produce their own food. Then animals feed upon the plants. They take in the nutrients the plants have made and stored. But that’s not all. Sunlight also helps a plant produce oxygen. Some of the oxygen is used by the plant, but a plant usually produces more oxygen than it uses. The excess oxygen is necessary for animals and other organisms to live. 　　The process of changing light into food and oxygen is called photosynthesis. Besides light energy from the sun, plants also use water and carbon dioxide. The water gets to the plant through its roots. The carbon dioxide enters the leaves through tiny  HYPERLINK /cpro/ui/uijs.php?c=newscf=1001ch=0di=128fv=0jk=f1449f2c3a35d52dk=openk0=openkdi0=0luki=1n=10p=baiduq=qnwzcprrb=0rs=1seller_id=1sid=2dd5353a2c9f44f1ssp2=1stid=0t=tpclicked3_hctu=u1984217u=http%3A%2F%2Fwww%2Eqnr%2Ecn%2Fwaiyu%2Fzhien%2Flg%2Flj%2F201501%2F1040380%5F2%2Ehtmlurlid=0 \t _blank openings called stomata.

Chloroplasts contain the chlorophylls that give plants their green color. The chlorophylls are the molecules that trap light energy. The trapped light energy changes water and carbon dioxide to produce
