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: -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: -Plants are producers. They make their own food, which creates energy for them to grow, reproduce and survive.

Detailed explanation-4: -As you probably know, the organisms at the base of the food chain are photosynthetic; plants on land and phytoplankton (algae) in the oceans. These organisms are called the producers, and they get their energy directly from sunlight and inorganic nutrients.

Detailed explanation-5: -PRODUCERS: At the bottom of the food chain, plants are natural producers and provide food and nutrients to consumers. HERBIVORES: Herbivores nourish on plants and insects. PREDATORS: Predators prey on herbivores or other predators. DECOMPOSERS: When an animal dies, scavengers and decomposers break them down.
