Approximately how many kilocalories per year does the deer mouse expend on thermoregulation?

  • A: 400 kcal
  • B: 800 kcal
  • C: 1,000 kcal
  • D: 2,000 kcal

Explanation

The deer mouse's total annual energy expenditure is 4,000 kcal. Observing the pie chart, the wedge for 'Thermoregulation' orange appears to be approximately one-fifth 20% of the total circle. Therefore, 20% of 4,000 kcal is 0.20 4,000 = 800 kcal.
