All plants, including the coconut palm tree in the picture are known as autotroph. An autotroph is any organism that makes its own food. They use light, water, and other chemical like carbon dioxide to produce food for itself, and plants do this in a process known as photosynthesis. A human wouldn’t be considered an autotroph because we don’t photosynthesize. Plants, although, are not the only autotrophs. Algae, phytoplankton, and some bacteria are also autotrophs that make food for themselves. Through photosynthesis, plants produce their food as a product known as glucose. Chemosynthesis is another process that some organisms use to make their own food.
