Two simplified food chains are shown here for a terrestrial and a marine ecosystem. Assuming there is 100% availability of energy for the primary producers for each chain, which statement describes the energy availability at other levels of the food chain?
A The energy availability decreases as you move up both food chains, with the top predators having the least energy availability.The energy availability decreases as you move up both food chains, with the top predators having the least energy availability.
B The energy availability increases as you move up both food chains, with the top predators having the most energy availability.The energy availability increases as you move up both food chains, with the top predators having the most energy availability.
C The energy availability increases as you move up the terrestrial food chain but decreases as you move up the marine food chain.The energy availability increases as you move up the terrestrial food chain but decreases as you move up the marine food chain.
D The energy availability remains the same as you move up both food chains since the first law of thermodynamics states energy can neither be created nor destroyed.
