Glucose is virtually the sole fuel for the human brain, except during prolonged starvation. The brain lacks fuel stores, thus requires a continuous supply of glucose. It consumes about 120 g daily which corresponds to an energy input of 420 kcal (1760 KJ), accounting for some 60% of the utilization of glucose by the whole body in the resting state.

Answer:
A. Chipmunks sleeping underground through the winter
Explanation:
A seasonal change in the behavior of a living organism is a change that occurs every year at a particular time. The reasons for the occurrence of such changes are so that the organism has advantage in survival in the environment. In this case we have the chipmunk that sleeps underground through the winter. We have an animal which exhibit a seasonal change every year, during the winter period. The reason for this is that the chipmunks have very quick metabolism, so if they are active during the winter they will starve because of lack of food. Instead, the chipmunks have evolved to hibernate during the winter, thus slowing down the work of their hurt during the winter and sleep, until the spring comes.
