What Are Producers in Biology? Producers are organisms that make their own food; they are also known as autotrophs. They get energy from chemicals or the sun, and with the help of water, convert that energy into useable energy in the form of sugar, or food. The most common example of a producer are plants.
A producer is a plant that makes its own food and provides food for consumers. Consumers are the animals that eat the food the producer makes. Producers besides cacti include the hanging chain cholla, a tree that produces spiny branches, and desert shrubs. Producers use the nutrients in the soil and sunlight to create food.
