Detailed explanation-1: -Grazing food chain (GFC) – This is the normal food chain that we observe in which plants are the producers and the energy flows from the producers to the herbivores (primary consumers), then to carnivores (secondary consumers) and so on.

Detailed explanation-2: -A food chain describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. After that when carnivores eat the herbivores, energy is transferred from one to the other.

Detailed explanation-3: -Answer and Explanation: Energy is passed from one organism to another when an organism consumes another organism, or when nutrients are absorbed. In terms of obtaining energy, there are three types of organisms: autotrophs, heterotrophs and decomposers.

Detailed explanation-4: -Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
