Final answer:
In the absence of predators, prey populations initially experience exponential growth, characterized by a rapid increase in size. However, this growth eventually transitions to logistic growth as resources become scarce and the population approaches carrying capacity.
Step-by-step explanation:
In the context of population dynamics and predator-prey relationships, the question "In the absence of the predator, the prey pop grows...... " revolves around the concept of how populations change when not limited by predation. The correct answer is: A. Rapidly. Initially, in the absence of predators, the prey population experiences exponential growth, where the number of individuals doubles at regular intervals, resulting in a rapid increase in population size. This phase of growth is characterized by a lack of constraints on the prey population, allowing it to grow quickly. However, it is important to note that this exponential growth does not continue indefinitely. Over time, as resources become scarce due to the increasing population, the growth pattern will shift to logistic growth. This is a more realistic model of population growth, where the population growth rate slows down and eventually levels off as it approaches the carrying capacity of the environment.
