When there are high levels of disturbance in a community, the number of K-selected species should increase along with the overall diversity of the community.

Question

Answer the following statement true (T) or false (F)

Answer 1

False

Clarify Question
• What is the key concept addressed by the question?
        o This question requires an understanding of K-selected species and the conditions are associated with those species.
• What type of thinking is required?
        o This is an application question; you need to apply your knowledge of disturbance and reproductive strategies in order to determine if the statement is true or false.

Gather Content
• What do you already know about K-selected species? What other information is related to the question? 
        o A habitat that experiences a high level of disturbance is not going to be a very stable environment. Are r- or K-selected species going to do better in an unstable environment? r-selected species are typically short-lived, have lots of offspring, and provide little or no parental care. K-selected species are typically long-lived organisms that produce a very small number of offspring that receive lots of parental investment.

Choose Answer
• Given what you now know, what information is most likely to produce the correct answer?
        o r-selected species are species that grow and disperse quickly and reproduce quickly and in large numbers. Therefore, they would be the first species to dominate an area in early succession.

Reflect on Process
• Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
        o You needed to apply your knowledge of reproductive strategies to the situation involving a high disturbance environment. Were you able to apply your knowledge about species that are able to adjust to rapidly changing environmental condition and how that relates to r- versus K-selected species?
