Answer:
Predation
Step-by-step explanation:
Predation is the interaction where one organism, the predator (red-tailed hawk), kills and eats another organism, its prey (praire dog).
It is not the other three because:
Prey evasion is when the prey attempts to avoid its predator; however, in this case, the prairie dog is being eaten by the red-tailed hawk.
Interspecific competition is when individuals of different species compete for the same resources in an ecosystem.
Herbivory is the consumption of plant material by animals, and herbivores are animals adapted to eat plants. There are no plants being involved in this scenario.
