4. only about 10 percent of the energy in an organism is passed on to the next level of a food chain. look at this food chain: grass → rabbit → hawk what percentage of the energy stored by the grass is passed on to the hawk?

The correct answer is - 1%.

The grass is a plant, thus it is a producer. It produces food for itself through the process of photosynthesis. The grass though is a food source for the rabbit. From the initial 100% energy from the grass, the rabbit manages to get only 10% of it, thus the rabbit will get just one tenth of the total energy of the grass. The hawk is predator, on the top of the food chain, and the rabbit is its prey. The rabbit only got 10% of the energy from the grass, and the hawk will only 10% of those 10% that the rabbit got. In this way, the hawk will get only about 1% of the initial 100% of energy that the grass had.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
