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.

true

Resource shortages triggered by increasing population size are density-independent limiting factors.

f, dependent

When you graph a population's exponential growth over time, you will have an S-shaped graph.

f, j-shaped

Method of sampling where a grid is marked off and areas are randomly chosen to count the population of species.

...

Based on their names, you know that the baboons Papio annubis and Papio cynocephalus do NOT belong to the same

species

For many species, there are often regional differences in their

taxa

The human population experienced exponential growth after

the industrial revolution began

Which of the following is a density-independent limiting factor?

...

Which would be least likely to be affected by a density-dependent limiting factor?

A small, scattered population

Each of the following is a density-dependent limiting factor EXCEPT

Figure 4-2 shows succession in an ecosystem. What organisms are found in the climax community for this ecosystem?

mix group of large trees

If a population grows larger than the carrying capacity of the environment, the

death rate may rise

population density

Which factor might NOT contribute to an exponential growth rate in a given population?

reduced resources

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

limiting factor

A wolf pack hunts, kills, and feeds on a moose. In this interaction, the wolves are

predators
