What is nutrition flow in ecosystem?

Nutrition flow in an ecosystem refers to the transfer of energy and nutrients through various trophic levels, from producers to consumers and decomposers. It begins with primary producers, such as plants, that convert solar energy into chemical energy via photosynthesis. Herbivores (primary consumers) then feed on these plants, followed by carnivores (secondary and tertiary consumers) that eat the herbivores. Decomposers break down dead organic matter, returning nutrients to the soil and completing the cycle, thus sustaining the ecosystem.
