How is the plant kingdom useful to us?
The plant kingdom has many uses for us. Through the process of photosynthesis, plants convert the solar energy into food (carbohydrates). They are primary producers, and we are dependent on them for our food. We, along with animals, either directly consume plants (fruits and vegetables, etc.) or indirectly by consuming animals. Thus, plants are the source of food for us.
Plants also consume carbon dioxide and generate oxygen. They are the primary supplier of oxygen in the atmosphere and also help in keeping the carbon dioxide concentration in check. We all need oxygen for our survival and thus, plants are essential for our existence.
Plants also minimize the soil erosion and protect the soil. Plants also provide us with wood which has a number of uses for mankind. Many plants also have medicinal properties and their parts are used in the pharmaceutical industry.
Hope this helps.
