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. Nearly all autotrophs use a process called photosynthesis to create “food” (a nutrient called glucose) from sunlight, carbon dioxide, and water.

Detailed explanation-2: -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: -Plants, which convert solar energy to food by photosynthesis, are the primary food source. In a predator chain, a plant-eating animal is eaten by a flesh-eating animal.

Detailed explanation-4: -The organisms that eat the primary producers are called primary consumers. Primary consumers are usually herbivores (plant-eaters), though they may be algae or bacteria eaters. The organisms that eat the primary consumers are called secondary consumers.
