Ecology Unit © It’s Not Rocket Science 2016 28 Practice: Population Ecology Answer the following questions. Show work as needed. 1. The type of population growth that most natural populations follow is . Sketch it on the graph to the right. 2. Add a dotted line to your graph to show the maximum population this environment can theoretically support. This is called the . 3. Can the line you drew in #2 change? Explain your thoughts. 4. The human population is increasing without limit. This is the same as growth pattern. Sketch it on the graph to the right. 5. Factors that cause a population to not grow exponentially are said to be . These can be biotic (meaning ) or abiotic (meaning .) Give examples of each below. 6. The amount of organisms in a given space is called the . Ecologists are more concerned with knowing about this than just population size because some limiting factors (usually the biotic ones) are and others (usually the abiotic ones) are . 7. Consider a meadow that is 10 miles by 10 miles. It has 100 deer in it. A different meadow is 5 miles by 2 miles and has 50 deer in it. Which population is more at risk for predation by hunters during deer season? Explain. 8. Consider the same populations of deer in the meadows in #7. Which population would be more at risk if a forest fire hit and burned their entire food source? Explain. 9. Which population, from #7, would disease have the greatest negative impact on? Explain, based on the type of limiting factor that disease is. 10. Which population, from #7, would a flash flood have the greatest negative impact on? Explain, based on the type of limiting factor that flash flooding is.

Ecology Unit © It’s Not Rocket Science 2016 29 Create two graphs based on the data provided. Then answer the questions below. Be sure to include all appropriate components of a graph in each. 11. Which population growth graph shows exponential growth? 12. Which population growth graph shows logistic growth? 13. Do either of the graphs (or both) reflect that the population has a carrying capacity? If so which? 14. In regards to your answer to #13, when does this population reach its carrying capacity? 15. In regards to your answer to #13, what is the carrying capacity for this population?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
