Kaibab Activity (think about it!) Age Structure Activity (think about it!) Central Case Activity NOTE: If you have an IEP and you are (a) taking your test in another location, (b) you think you might want extended time, or (c) you have special needs for your tests with regard to choices, etc, YOU MUST LET ME KNOW TODAY! Modifications need to be made PRIOR to you sitting down for the test (i.e. you may not start the test in class during EnviSci and finish it another day without appropriate modifications!) Vocabulary.

Reference your notes if you need them! Question Answer ORGANISM POPULATION 1) What is the correct order of levels of organization? COMMUNITY ECOSYSTEM BIOSPHERE 2) Describe what a graph would look like if a population has exponential growth (the shape). J SHAPED 3) Describe what a graph would look like if a population has logistic growth (the shape). S SHAPED 4) What are the three types of population distributions? Draw a pic of each…use dots to represent individuals. A SEE YOUR NOTES B C 5) If a scientist can’t physically count each organism in a population, what technique might he employ to estimate the size? 6) Name three abiotic factors. SAMPLING TECHNIQUES 7) Name three biotic factors. PLANTS, ANIMALS, MICROORGANISMS 8) Name three density-dependent factors. COMPETITION, PREDATION, DISEASE 9) Name three density-independent factors. EARTHQUAKE, TORNADO, MUDSLIDE 10) What is the equation for determining population growth? (IMMIGRATION + BIRTHS) – (EMIGRATION + DEATHS) 11) In one year in a population of 100 squirrels, 12 die of natural causes and 22 are born. Seven juveniles leave the population to establish territories elsewhere, and 4 new individuals arrive from a different patch of forest. What is the growth rate of the population per 100 individuals? 12) What is the % growth for the previous question? (4 + 22) – (7 + 12) = 26 – 19 = 17 13) Name the three types of survivorship curves and an example of an organism in each. TYPE I – HUMAN TYPE II – BIRD TYPE III - FROG MOSTLY YOUNG; GROW 14) What does an age structure diagram that is pyramidal show? (Mostly young or old?) Will this population grow, stay the same, or decline? 15) What does an age structure diagram that is the same width top to bottom show? (Mostly young or old?) Will this population grow, stay the same, or decline? 16) What does an age structure diagram that is top-heavy show? (Mostly young or old?) Will this population grow, stay the same, or decline? WEATHER, ATMOSPHERE, LIGHT 17% SAME NUMBERS OF OLD AND YOUNG; STAY THE SAME MOSTLY OLD; DECLINE
