It is because they can make their own food.

Explanation:

Green plants have a pigment called chlorophyll, which allows them to absorb light, and with carbon dioxide gas, will produce glucose and oxygen gas in return. This process is called photosynthesis.

Photosynthesis is the way which plants make food. Carbon dioxide gas and water with the help of sunlight and chlorophyll make glucose and oxygen. The chemical reaction for this is:

#6CO_2+6H_2Ostackrel("sunlight")stackrel("chlorophyll")rarrC_6H_12O_6+6O_2+ATP#

The #ATP# produced is made from the breaking down of glucose. It is the main source of energy for the cells.
