Answer:
Plantae is the second-largest kingdom after Animalia and is made up entirely of plants: from giant redwoods to miniscule mosses, creeping vines to towering sunflowers, plants come in all shapes and sizes. Usually plants are autotrophic (self-feeding), and receive their energy through photosynthesis, although some are parasitic, which means that they feed on other plants or animals and harm them in the process.
Almost all plants have chlorophyll, a pigment that gives plants a green color and allows them to photosynthesize, which is a process where plants convert the sun’s energy into chemical energy. Plants use carbon dioxide, a chemical produced by humans and other heterotrophs, and release oxygen as a waste product; in fact, they produce most of the earth's oxygen. Plants are not only the main food source for humans, but for all kingdoms, and provide basic necessities for humans as well, such as clothing, medicine, and shelter. Plants are essential to life on earth, critical for the survival and thriving of all other kingdoms.
