Name: ________________________________________ Block: _____ Date: _____/_____/_____ ENVIRONMENTAL SCIENCE Respond to all of the following problems in preparation for your Chapter 8 Test. Chapter 8 Study Guide: Understanding Populations 1) What term generally describes an organism’s way of life? _______________ 2) What term describes the arrangement of a population within a given area? ____________________ 3) What term describes a group of individuals of the same species, living in a given area? __________________ 4) What 2 terms describe a species interaction where one organism feeds on the other? ____________________ ________________________ 5) What does a population’s birth rate minus its death rate equal? _____________________________________ 6) What term describes a species interaction where organisms attempt to use the same resources? ________________________ 7) What term describes a species interaction where one organism benefits and the other is unaffected? ________________________ 8) What term describes the maximum population that an ecosystem can support indefinitely? _______________ ___________________ 9) What term describes a way to reduce competition between species? _________________________________ 10) What term describes a factor that determines the carrying capacity of an ecosystem? ____________________ ______________________ 11) Compare the reproductive potential of humans to that of bacteria. ___________________________________ ________________________________________________________________________________________ 12) Give an example of a population. ____________________________________________________________ 13) What is population density? _________________________________________________________________ ________________________________________________________________________________________ 14) Is a cow feeding on grass in a pasture an example of predation or parasitism? Explain your answer. ________________________________________________________________________________________ ________________________________________________________________________________________ ________________________________________________________________________________________ 15) Describe the relationship roles of a Canadian lynx and a snow-shoe hair. _____________________________ ________________________________________________________________________________________ 16) In which 2 types of species interactions is neither organism harmed? ________________________________ ______________________________ 1 Name: ________________________________________ Block: _____ Date: _____/_____/_____ ENVIRONMENTAL SCIENCE 17) Give an example of a species with random population dispersion? __________________________________ 18) What is the difference between density-dependent deaths and density-independent deaths? Provide an example of each. _________________________________________________________________________ ________________________________________________________________________________________ ________________________________________________________________________________________ ________________________________________________________________________________________ 19) Some deer have evolved thick fur to help them survive colder climates. Explain why the thick fur is an example of an adaptation and not of coevolution. ________________________________________________ ________________________________________________________________________________________ 20) A certain species of plants shows exponential growth after being introduced in a new area. What would happen to this plant’s population after a few years? ______________________________________________ 21) Consider the relationship between a rabbits and coyotes in a common area. a. If the rabbit population suddenly experienced exponential growth, what would happen to the coyote population? Why? _________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ b. If the rabbit population exceeds the carrying capacity, what will happen to the coyote population? Why? _________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ 22) List and briefly describe the 5 types of species interactions. Provide an example for each and describe the roles of the organisms involved. a. _______________________________________________________________________________ _______________________________________________________________________________ Example: _________________________________________________________________________ __________________________________________________________________________________ b. _______________________________________________________________________________ _______________________________________________________________________________ Example: _________________________________________________________________________ __________________________________________________________________________________ 2 Name: ________________________________________ Block: _____ Date: _____/_____/_____ ENVIRONMENTAL SCIENCE c. _______________________________________________________________________________ _______________________________________________________________________________ Example: _________________________________________________________________________ __________________________________________________________________________________ d. _______________________________________________________________________________ _______________________________________________________________________________ Example: _________________________________________________________________________ __________________________________________________________________________________ e. _______________________________________________________________________________ _______________________________________________________________________________ Example: _________________________________________________________________________ __________________________________________________________________________________ 3
