Energy flows through the ecosystem through different levels, starting with the process of photosynthesis. The process ends when the carnivores die and get decomposed, thereby becoming food for plants and starting the cycle again. Since the energy gets used up throughout the entire cycle of flowing through the ecosystem, it cannot be recycled. Food chains, food webs, trophic levels, pyramids of biomass and energy transfer efficiency, food chains Similarly, energy is also transferred through organisms in a food chain when consumers eat plant producers Food chains are a simple linear way of showing 'what eats what' in an ecosystem.
