Why do Hawks have less energy than rabbits?

Hawks have less energy than rabbits primarily due to their position in the food chain. As predators, hawks require a higher energy intake from their prey, which in this case are smaller animals like rabbits. However, the energy transfer between trophic levels is inefficient, typically losing about 90% of energy at each level, meaning hawks must consume multiple rabbits to sustain their energy needs. In contrast, rabbits, as herbivores, convert plant energy more directly into their own energy.
