Which pair of predators exemplify resource partitioning by being active during different periods of time? 

A)  hawks and owls 
B)  lions and tigers 
C)  hummingbirds and bees 
D)  zebras and antelopes

Hawks and owls are both birds of prey that hunt small mammals and birds, but they have different activity patterns. Hawks are diurnal, meaning they are active during the day, while owls are nocturnal, meaning they are active at night. This allows them to hunt without direct competition with each other, and is an example of resource partitioning.
