Plants are known as primary producers because they make their own food by a process known as photosynthesis. They take sunlight and use it to help make food. Plants are at the bottom level in the food chain and they make all the food and energy that is found in the ecosystem. Without plants, other animals and even humans would not survive because we would not have the energy to produce our own food. Plants produce all the energy; then it gets transferred through every other living thing on this planet.
