Answer:
Trophic levels are part of an energy cascade that allows for energy consumption, conservation, and retention.
Explanation:
By altering trophic levels in an ecosystem, there is shift between the readily energy available within one specfic trophic system. If you remove wolves, for instance, normal prey could increase en-masse. In this way, the removal of wolves allows for an energy expansion that increases and accelerates the growth of that prey species. In their growth, they attain their energy from elsewhere, say specific plants off which they eat.
