Key Concepts Covered

➡️ Trophic levels – The distinct feeding positions organisms occupy within an ecosystem, from producers to top predators
➡️ Energy transfer – How energy moves through trophic levels, with most energy lost at each step
➡️ Biomass decrease – The reduction of biological material as energy moves up the food chain
➡️ Food chain sequences – The chain of interactions from producers to apex predators
➡️ Ecosystem efficiency – Why energy transfer between trophic levels is only approximately 10% effective
