Exam 5: Biodiversity, Species Interactions, and Population Control

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

Which of the following would exhibit primary succession?

Specialized traits or behaviors that allow a reduction of interspecific competition through species specialization in resource use, allow for ____________________.

Which of the following best describes the two important aspects needed to stabilize living systems?

A logistic growth curve depicting a population that is limited by a definite carrying capacity is shaped like the letter ____.

Clearly describe in what ways predation is actually beneficial to the prey population.

An old elk dies during a snowstorm in Yellowstone National Park. When the storm clears, coyotes forage on the fresh flesh of the elk. Following this, birds such as vultures forage on the rotting meat. Lastly, insects and worms consume the last of the fragments of tissue of this once large and magnificent animal. This is an example of

An area in primary ecological succession would be a suitable habitat for a population of hardwoods because of the availability of resources.

Compare and contrast primary succession and secondary succession.

An exponential growth curve depicting an ever-growing population is shaped like the letter ____.

There are ____________________ limits to population growth in nature.

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

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

Some predators hide in plain sight before ambushing their prey by virtue of their____________.

Predation and parasitism are examples of ecological interactions in which one species takes advantage of another species.

____________________ is the combination of all factors that act to limit the growth of a population.

Births and deaths are the only two factors that determine population sizes.

The graph above shows the census count for two animal species, A and B, over a 31 year period. Animal A and animal B have a predator-prey relationship. -Briefly state why cat litter is a problem for sea otters.
