NEET BIOLOGY

Detailed explanation-1: -The green plants in the ecosystem are called producers and they make the first trophic level of the food chain having the greatest amount of energy.

Detailed explanation-2: -The bottom and largest level of the pyramid is the producers and contains the largest amount of energy. As you move up the pyramid, through the trophic levels to primary, secondary and tertiary consumers, the amount of energy decreases and the levels become smaller.

Detailed explanation-3: -Energy Flow Through an Ecosystem At the base of the pyramid are the producers, who use photosynthesis or chemosynthesis to make their own food. Herbivores or primary consumers, make up the second level. Secondary and tertiary consumers, omnivores and carnivores, follow in the subsequent sections of the pyramid.

Detailed explanation-4: -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-5: -The first level of the food chain is the primary producer. This level is occupied by plants. Plants produce organic molecules using solar energy from the sun during photosynthesis and they are thus responsible for making energy available to the animals or consumers.
