A producer makes organic food from inorganic inputs using an energy source. Green plants and algae use light. Consumers obtain organic material by eating other organisms or their products. These examples focus on photosynthetic producers.

Worked example

Grass uses light to make sugars and is a producer. A rabbit eating grass is a consumer.

A food-chain model reads grass: producer to rabbit: consumer to fox: consumer. Each arrow points from the food organism to its consumer; this is a simplified chain, not a complete food web.
