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.
Detailed explanation-2: -Because autotrophs do not consume other organisms, they are the first trophic level. Autotrophs are eaten by herbivores, organisms that consume plants. Herbivores are the second trophic level.
Detailed explanation-3: -First level of heterotroph is an organism that feeds on plants. A second order heterotroph is an organism that feeds on a first order heterotroph. A food chain represents only one possible route for the transfer of matter and energy through an ecosystem.
Detailed explanation-4: -Plants are autotrophs and convert the solar energy into food by photosynthesis hence they form the first trophic level of a food chain. They are consumed by primary producers that are the herbivores.
