Autotroph

Most plants on land or water are autotrophs, which are the producers in a food chain who provide the consumers with energy. Autotrophs are self feeding organisms who produce organic compounds (carbohydrates, fats, and proteins) using their surroundings, most commonly by means of light. This process is called photosynthesis. This picture shows a plant that is a common autotroph who uses the process of photosynthesis to convert organic compounds for energy use.
