Question

A breeding pair of rabbits escaped from their cage behind a farmer’s barn. The farmer observed the rabbits and kept data on their population size for ten years. During this time, the rabbits reproduced and their offspring reproduced many times. The fenced, undisturbed two acres where the rabbits live support populations of predators, such as hawks and snakes, as well as a limited supply of grass and water. At the end of the ten years, the farmer graphed the data he collected. Which of the following best describes his graph?
Question 3 options:

The graph is generally J shaped showing exponential growth.

The graph is generally S shaped showing logistic growth.

The graph is a horizontal line showing the effects of predation.

The graph angles up in a straight line at 45° showing the effects of ample resources.

Answer 1

Answer:

I think the answer is B

Explanation:

Because using logic on this situations is best idk

Answer 2

Answer:

The graph is generally S shaped showing logistic growth.

Explanation:

The graph of the farmer will be generally S shaped showing logistic growth.

There are two types of population growth:

• The logistic growth (S shaped)
• The exponential growth (J shaped)

For the logistic growth, the population grows gradually as organisms try to establish themselves in their new environment. After getting acclimatized with the environment, the population grows more rapidly and then levels off due to limited factors such as predation and competition for foods. The point of leveling off is refers to as the carrying capacity (k).

For the exponential growth, the population of organisms continue to grow rapidly indefinitely after getting acclimatized with the environment. This type of growth only occur in the absence of population limiting factors.

In this case, after acclimatization and rapid growth of the rabbit's population, the population then levels off due to limited supply of grass and water as well as predation by hawks and snakes.

Hence, the graph for population growth will be S shaped showing logistic growth.
