Detailed explanation-1: -Producers, also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms.

Detailed explanation-2: -Food Chains Plants make their own food through a process called photosynthesis. Using the energy from the sun, water and carbon dioxide from the atmosphere and nutrients, they chemically make their own food. Since they make or produce their own food they are called producers.

Detailed explanation-3: -The parts of a food chain are producers, consumers, and decomposers. Producers are plants that produce, or create, their own food by using light energy from the sun, carbon dioxide from the air, and water from the soil. This process of creating their own food is called photosynthesis. Animals are consumers.

Detailed explanation-4: -Trophic levels are the order the organism is placed on the food chain. These levels are divided into producers (first), consumers (second, third and fourth) and decomposers (fifth).

Detailed explanation-5: -Plants are producers. They make their own food, which creates energy for them to grow, reproduce and survive. Being able to make their own food makes them unique; they are the only living things on Earth that can make their own source of food energy. Of course, they require sun, water and air to thrive.
