How Does Energy Enter And Leave Grazing Food Chain?

In a grazing food chain, energy enters primarily through photosynthesis, as plants (producers) convert sunlight into chemical energy. Herbivores (primary consumers) then consume these plants, transferring energy up the chain. As energy moves to higher trophic levels, such as carnivores (secondary consumers), a significant amount is lost as heat through metabolic processes. Ultimately, energy leaves the food chain when organisms die and decompose, returning nutrients to the soil, or through respiration and waste products.
