Question

Plz help based on graph 1. what is happening to the population of the mice between days 0 and 7? suggest some possible reasons why this trend is occurring? 2. what is the approximate carrying capacity of this mouse population from observing the graph? how do you know this ? 3. the farmer who owns the barn has been given two barn cats how will this affect the size of the mouse population explain your answer 4. What are some other factors that will change the size of the mouse population in the future?

Answer 1

1.  The population of the mice seemed to grow until day 7.  This likely occurred do to the fact that the mice kept reproducing and they had enough resources to sustain the population growth.
2.  the carrying capacity is around 24 since that is when they reach population equilibrium.
3.  This will lower the mice population since it will introduce a predator that will lower the carrying capacity.
4.  The mice population can change in the future if more predators are introduced, if predators die out/go away, if an invasive species is introduced that competes with the mice for resources, if the climate changes, and if the amount of resources available to the mice increases or decreases.
I hope this helps. let me know in the comments if anything was unclear.
