Producers (autotrophs) capture the sunlight energy during photosynthesis to make the food that consumers (heterotrophs) eat.
Below are the definitions of the terms used within the sentence:
Producer / autotroph- An organism that is able to make its own food. This is often done via photosynthesis. Photosynthesis is the process that captures sunlight as the energy source to drive the combination of carbon dioxide and water in order to produce oxygen and a sugar known as glucose. Photosynthesis requires chlorophyll housed within chloroplasts. Thus, plant cells are required. Examples of producers are plants and algae.
Consumer / heterotroph- An organism that eats other things. Examples of heterotrophs are animals and fungi.
Feeding relationships can also be diagramed with either food chains, trophic level pyramids, or food webs. Links to each type of diagram are provided below.
