Final answer:
Plants are called autotrophs because they produce their own food using carbon dioxide during photosynthesismust rely on consuming other living things to obtain energy..
Step-by-step explanation:
Plants use carbon dioxide from the air during the process of photosynthesis and are therefore called autotrophs. Autotrophic organisms, such as plants, algae, and certain bacteria like cyanobacteria, are capable of producing their own food from inorganic substances using light or chemical energy. While plants and algae use light to synthesize food, making them photoautotrophs, some bacteria use chemical energy, and are thus called chemoautotrophs. In contrast, heterotrophs are organisms that cannot synthesize their own food and must rely on consuming other living things to obtain energy.
Plants use carbon dioxide from the air and are therefore called autotrophs. Autotrophic plants can make their own food from inorganic raw materials, such as carbon dioxide and water, through photosynthesis in the presence of sunlight. They use light to manufacture their own food and are responsible for the production of oxygen through photosynthesis. Other organisms, such as animals and most bacteria, are called heterotrophs because they rely on the sugars produced by autotrophs for their energy needs.
