Detailed explanation-1: -Producers are generally found at the beginning of a food chain. Which statement best explains why this is true? Producers are usually smaller in size than consumers.
Detailed explanation-2: -All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of a food chain always starts with plant life and ends with an animal. Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.
Detailed explanation-3: -So, the correct answer is ‘Green plants’
