Answer the following statement(s) true (T) or false (F)
1. True or False: An r-selected species is more likely to become an invasive pest than a K-selected species. 2. Interspecific competition can affect the phenotypic characteristics of organisms. Clarify question: What is the key concept addressed by the question? What type of thinking is required? Gather Content: What do you already know about interspecific competition? What other information is related to the question? Choose Answer: Given what you now know, what information is most likely to produce the correct answer? Reflection 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? 3. Geographical allopatry between species is definitive evidence of interspecific competition.
