Exam 5: Biodiversity, Species Interactions, and Population Control

Factors that act to limit the growth of populations are collectively called

The graph above shows the census count for two animal species, A and B, over a 31 year period. a.Animal A and animal B have a predator-prey relationship. -What description would apply to the predator species in the graph above if the prey species were its only source of food? What assumptions could we make about that predator species if this were the case?

Match the items listed below with the appropriate choice -On the exponential growth of reindeer figure, choose the portion of the graph that represents the number of reindeer that can be sustained indefinitely in a given area.

Match the items listed below with the appropriate choice -On the ecological succession figure, choose the letter that represents the step in which shrubs grow.

The ecological process that would result in a localized change in species composition following a severe volcanic eruption would best be described as ____________________.

Insect-eating warblers reduce interspecific competition by which of the following?

You are an evolutionary entomologist. a.You have observed beetles that can raise their abdomens and give off a defensive chemical that generally repels predators. You discover a new species of beetle that raises its abdomen in a threatening way similar to the first species, but no defensive chemical is given off. You are most likely to characterize this defensive strategy as a form of

Mistletoe is an example of a(n) _____________________.

There are ____________________ limits to population growth in nature.

Prey are least likely to defend themselves against predators by

Inertia is not a feature of grassland ecosystems, but resilience is.

The human population can maintain an exponential growth rate indefinitely because of technology.

Match the items listed below with the appropriate choice -A tiny fish called a wrasse lives in and around the mouth of sharks. a.It cleans up the debris left after the shark eats flesh, and it gains protection by living in the shark's mouth.

All of the following are external parasites except

-As indicated in this image, when different species of warblers inhabit the same area, is food competition reduced?

Carrying capacity is the population size (or density) at which the environment is saturated.

Match the items listed below with the appropriate choice -Sea lampreys attach themselves to fish such as trout.

Compare and contrast primary succession and secondary succession.

A relationship in which a member of one species obtains its nourishment by living on, in, or near a member of another species over an extended time is best labeled

Clearly explain the current view of succession in ecosystems.
