Question

evidence for the cer write up
the following graphs show simulated or predicted population growth trends of a white footed
mouse. each graph shows the growth trend for the mice when its limiting factors are changed. use
this data to support your claim in your cer write up.
graph 1
carrying capacity, niche, and population growth
graph 1 shows the population growth trend that is ideal for the white - footed rat.

1. what is its carrying capacity (estimate given what you see on the graph.)
2. what variables does the graph display?
3. what is the relationship between the variables?

Explanation:

1. Carrying capacity is the maximum population size an environment can sustain. By observing the graph where the population stabilizes (fluctuates around a certain value), we estimate it.
2. Variables in a graph are what is plotted on the axes. Here, one axis is time (months) and the other is population size.
3. The relationship is that as time (months) passes, the population grows until it reaches carrying capacity and then fluctuates around it.

Answer:

1. Approximately 90 (estimated by looking at the stable - fluctuating range on the population axis of the graph).
2. Time (in months) and the population size of white - footed mice.
3. The population of white - footed mice grows over time (months) until it reaches a carrying capacity and then fluctuates around that carrying capacity.
