getting the prey against the cheetahs, mostly by using physical force against the cheetahs and then
stealing the food. What is this an example of?
A. Exploitation competition
B. Interference competition
C. Interspecific competition

deer. Name the isolating mechanism working in this case.
A. Dispersal isolation
B. Vicariance isolation
C. Missing link isolation
D. Gametic isolation
E. None of the above
