Saguaro kangaroo rats generally leave watering holes, where food and water are abundant, during the day, while Sonoran kangaroo rats remain near these same watering holes and continue foraging throughout the day Although Sonoran kailgaroo rats have larger and more frequent litters, they are generally outnumbered by the Saguaro kangaroo rat. Which of the following, if true, would best resolve the apparent paradox described above?
A. Several species of successful rodents also leave the streams and watering holes during the day
B. The Saguaro kangaroo rat matures much more slowly than the Sonoran kangaroo rat because of its relatively limited food supply.
C. Many of the predators of kangaroo rats, such as falcons and rattlesnakes, are only active around streams during the day.
D. Saguaro kangaroo rats are more sensitive to sunlight than are Sonoran kangaroo rats.
E. Sonoran kangaroo rats are reproductive to a greater age than are Saguaro kangaroo rats.
