Explain how energy is transferred through a food web and food chain using the law of conservation of energy.

Energy is transferred with 90 percent less than the previous amount. For instance, producers start with 100 percent of energy considering they, well, produce the energy. Then, an herbivore comes and eats said producer, but only receives 10 percent of the energy. And so on and so forth as energy decreases as more consumers come along, which is why those at the top of the food web/chain typically eat more.

Hope this helps!
