Even though I used it in a DE class, my students still struggle with graphing and critical thinking. However, shortage in the number of bulls that could be distributed to the farmers for subsequent breeding remains a challenge in some countries of West Africa. How about robustness to the value of the parameter $r$? (Criticism of the Exponential Growth Model) When a quantity like the rabbit population grows exponentially, there is a xed time for which any initial quantity will double in size. Feeling pretty smug that you've got everything under control, you are ready to test your model and demonstrate how well this harvesting strategy will work to control the rabbit population. For the sake of discussion, let's suppose that k = .1 rabbits per month per rabbit.

How does the concept of stability explain your results? Worksheet 13: Population Growth . However, it is not enough. How can you tweak your function $h(p_t)$ so that it has less of a drastic effect? Even if the rabbit population ended up being 500 or 2000, that would be close enough to the (fairly arbitrary) ideal population size of 1000. They report back that the rabbit population seems to be increasing by 20% each month. endobj In the last section, students analyze trends in human population size and some of the factors that affect the earth's carrying capacity for humans. If $r$ were really 0.2, what value of $a$ would make the equilibrium be 1000? Basically, we analyze this growth process using. 2004, International Journal of Applied Mathematics & Statistics IJAMAS; Vol. That's funny, as long as $b$ is not exactly the same as $r$, the situation doesn't look good. \text{change} &= \text{reproduction} - \text{harvested} (You can change $r$ and $a$ by typing numbers in their boxes.)
