Let's explore what happens to the size of a population when it overshoots its carrying capacity. Sometimes, for a brief period of time, populations can exceed their carrying capacity. This can happen, for example, if food becomes a limiting factor; there may be a delay before reproduction declines, causing the population to exceed its carrying capacity briefly. 1. Assume that max is 1.0 and the carrying capacity is 2,000. Calculate the population growth rate when N= 2,100 and when N= 2,500 individuals. 2. If max is doubled, predict how the population growth rate will change for the two populations given in the previous problem. Then, calculate the population growth rate for the same two cases above, except this time assuming max is 2.0. 3. Sometimes after a population briefly exceeds their carrying capacity, there will be a drop in population numbers well below their carrying capacity before it begins increasing again. What is a possible explanation for the drop seen after populations exceed their carrying capacity?

Question
Let's explore what happens to the size of a population when it overshoots its carrying capacity. Sometimes, for a brief period of time, populations can exceed their carrying capacity. This can happen, for example, if food becomes a limiting factor; there may be a delay before reproduction declines, causing the population to exceed its carrying capacity briefly. 1. Assume that rmax is 1.0 and the carrying capacity is 2,000. Calculate the population growth rate when N= 2,100 and when N= 2,500 individuals. 2. If rmax is doubled, predict how the population growth rate will change for the two populations given in the previous problem. Then, calculate the population growth rate for the same two cases above, except this time assuming rmax is 2.0. 3. Sometimes after a population briefly exceeds their carrying capacity, there will be a drop in population numbers well below their carrying capacity before it begins increasing again. What is a possible explanation for the drop seen after populations exceed their carrying capacity?
