Compare exponential growth of organisms that reproduce rapidly with exponential growth of organisms that reproduce slowly.
If one population of pine trees consists of 25 trees in 5 square kilometers and another population consists of 25 trees in 2 square kilometers, which population has the higher density? Why?
Infer Consider the following statement: "Size and shape are NOT reliable indicators of how closely different organisms are related." What information shown in Figure 18-6 supports this statement?
Infer If you were adding a column to Figure 18-6 for the protist species Amoeba proteus, would this species share any taxonomic category with any of the other organisms in the table? Explain your answer.
Interpret Tables How many different kingdoms are represented by the organisms listed in Figure 18-6? What are they?
Interpret Tables Which level of taxonomic category shown in Figure 18-6 indicates whether an organism is a mammal or not?
Interpret Tables Which two organisms listed in Figure 18-6 are most closely related to each other? Explain.
Draw Conclusions What is the most likely reason why the population of P. caudatum decreased in Graph III of Figure 5-5?
Observe What type of population growth curve can be observed in Graphs I and II of Figure 5-5?
Interpret Graphs From Figure 5-5, which species has the greater growth rate overall when the species are grown together? Describe the growth curve of P. caudatum in Graph III.
Figure 4-8 shows a decrease in the deer population after 1925. Give one possible reason for this population decline. Explain your reasoning.
Linnaeus's system of classification has seven taxonomic levels.
Resource shortages triggered by increasing population size are density-independent limiting factors.
When you graph a population's exponential growth over time, you will have an S-shaped graph.
Method of sampling where a grid is marked off and areas are randomly chosen to count the population of species.

How is parasitism different from commensalism?
one organism is harmed in parasitism and no organisms are harmed in commensalism
Something that controls the growth or size of a population is a
