Answer the following statements true (T) or false (F)
1. Modern humans show a type I survivorship curve. 2. K-selected populations tend to reproduce quickly. 3. Exponential growth is rare because resources are usually limiting. 4. r-selected species tend to have type III survivorship curves. 5. Drought and floods are considered to be density-dependent factors potentially affecting population size.
You have been assigned to address a problem of overpopulation of species X in a nearby county. One of the members of your team suggests introducing species Y, which is a natural predator of species X, but not normally found in the area. After some discussion, you go ahead and introduce species Y. What aspects of the hierarchical organization may be affected within a period of a several years?
A. organism, population, species B. population, species, community, biosphere C. population, species, community D. population, community Clarify Question 1. What is the key concept addressed by the question? 2. What type of thinking is required? 3. What key words does the question contain and what do they mean? Gather Content 1. What do you know about hierarchical organization?How does it relate to the question? Consider Possibilities 1. What other information is related to the question? Which information is most useful? 2. If a predator is added which levels of structure would be affected? Choose Answer 1. Given what you now know, what information and/or problem solving approach is most likely to produce the correct answer? Reflect on Process 1. Did your problem-solving process lead you to the correct answer? If not, where did the process breakdown or lead you astray? How can you revise your approach to produce a more desirable result? 2. This question asked you to predict the impact of a predator on different levels of a hierarchical system.If you got the correct answer, great job! If you got an incorrect answer, where did you get stuck?
