Compare and contrast producers (autotrophs) and consumers (heterotrophs).
A producer (autotroph) is an organism that captures energy and matter from its surroundings to produce sugars and other molecules. Most producers capture energy from sunlight to make their food. They get the matter they need from gas molecules captured from air and water absorbed from the environment. Without access to sunlight, air, and water, a producer cannot make its own food and may die.
A consumer (heterotroph) is an organism that gets matter and energy by eating or absorbing other organisms as food. Organisms that cannot produce their own food using photosynthesis are consumers.All predators—whether they are herbivores, carnivores, or omnivores—are consumers. Some consumers eat producers, while others eat other consumers.
