POGIL - Population Growth by Jeremy Mohn https://padlet.com/jmohn/10i3u9eaw4z8 Hour 2 en-us 2018-03-02 18:11:30 UTC 2025-11-25 12:41:17 UTC hello@padlet.com 15. In most natural populations rapid exponential growth is unsustainable. As populations increase, environmental resistance causes the growth rate to slow down, until carrying capacity is reached. With your group, brainstorm several factors that could be considered as environmental resistance. https://padlet.com/jmohn/10i3u9eaw4z8/wish/239180476 Group 6: Factors that can be considered as environmental resistance include depletion of resources, size of environment, and competition from other species. ]]> 2018-03-07 15:03:20 UTC https://padlet.com/jmohn/10i3u9eaw4z8/wish/239180476 12. The maximum population an environment can sustain is affected by environmental factors that cause the population to level out or become stable. What term is used to describe this level of logistic growth? https://padlet.com/jmohn/10i3u9eaw4z8/wish/239181677 Group 5:  Carrying Capacity. ]]> 2018-03-07 15:04:53 UTC https://padlet.com/jmohn/10i3u9eaw4z8/wish/239181677 5. Which of the three types have the highest number of individuals that reach reproductive age? https://padlet.com/jmohn/10i3u9eaw4z8/wish/239181938
Group 1: Type 1- humans ]]> 2018-03-07 15:05:16 UTC https://padlet.com/jmohn/10i3u9eaw4z8/wish/239181938 16. Diagram B shows that the population size fluctuates around th carrying capacity. Considering what you know about interactions in the environment, discuss with your group some of he factors that could cause these fluctuations. In your answer you should relate these factors to the information from Model 1. https://padlet.com/jmohn/10i3u9eaw4z8/wish/239185514 Group 7: There are times of prosperity with fewer organisms competing for resources causing population to increase. When the population becomes too large there will be too many organisms competing for resources causing the population to fall again. Migration and emigration also causes the population to fluctuate.]]> 2018-03-07 15:10:17 UTC https://padlet.com/jmohn/10i3u9eaw4z8/wish/239185514 8. Under the circumstances might human populations not show Type 1 survivorship? https://padlet.com/jmohn/10i3u9eaw4z8/wish/239185944 Group 4: Having kids at an age younger than societal norms could raise the birth rate and change how carefully kids are raised. Lack of access to health care and unsanitary conditions also result in a higher child death rate.]]> 2018-03-07 15:10:55 UTC https://padlet.com/jmohn/10i3u9eaw4z8/wish/239185944 7. Consider the evolutionary strategies that each survivorship type has developed for producing and rearing their young. Propose an explanation for why type I survivors have the highest relative number of individuals/1000 births that survive until they reach post-reproductive age? https://padlet.com/jmohn/10i3u9eaw4z8/wish/239186940 Group 3: Type I organisms raise their offspring and protect them until adulthood which avoids the risk of competition eliminating these individuals from their environment before post-reproductive age. Type I survivors have more immunity to fend against disease (health resources, medical treatments) and have greater access to food, water, and necessary resources to survive compared to other species during their early years. ]]> 2018-03-07 15:12:14 UTC https://padlet.com/jmohn/10i3u9eaw4z8/wish/239186940
