If a snake receives 200 calories of energy from eating a rabbit how much of that energy is passed on to a hawk?

When a snake consumes a rabbit and receives 200 calories of energy, only a portion of that energy will be transferred to a hawk that eats the snake. Typically, about 10% of the energy at one trophic level is passed on to the next level due to energy loss through metabolic processes, heat, and waste. Therefore, if the hawk eats the snake, it would receive approximately 20 calories of energy from the original 200 calories consumed by the snake.
