If a rabbit consumes 500 calories of plants how much would that be passed on to a hawk?
When a rabbit consumes 500 calories of plants, not all of those calories will be passed on to a hawk that eats the rabbit. Typically, only about 10% of the energy from one trophic level is transferred to the next due to energy loss through metabolism, heat, and waste. Therefore, if a hawk consumes the rabbit, it would receive approximately 50 calories from the original 500 calories consumed by the rabbit.
What is control of energy intake?

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.
