Detailed explanation-1: -Producers make up the first trophic level. Producers, also known as autotrophs, make their own food and do not depend on any other organism for nutrition. Most autotrophs use a process called photosynthesis to create food (a nutrient called glucose) from sunlight, carbon dioxide, and water.
Detailed explanation-2: -The starting source of the trophic level in the ecosystem is the sun, which gets utilized by autotrophs. The other below trophic level is known as heterotrophs that cannot manufacture their food hence; has to depend upon the autotrophs to fulfill their food needs.
Detailed explanation-3: -The only level that directly receives energy from the sun is the first level or the level of producers .
Detailed explanation-4: -The producers form the first trophic level. The herbivores or the primary consumers form the second trophic level. The carnivores form the third trophic level.
Detailed explanation-5: -Autotrophs are the organisms that can produce their own food using sunlight as the source of energy. Since they produce their own food they are called producers. 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.
