Exam 5: Biodiversity, Species Interactions, and Population Control

Which of the following is the most common interaction between species?

Hawaiian honeycreepers have evolved into species with specialized niches, which has increased the competition between these species.

Species can, over a long period of time, develop adaptations that allow them to reduce or avoid competition by sharing resources.This is called

Five warblers in the state of Maine have evolved to share food resources and reduce food competition through ____________________.

Large mammals, such as humans, whales, and elephants, are especially vulnerable to extinction because of their reproductive patterns.

All of the following are forms of nondestructive behavior between species except

The most common interaction between species is commensalism.

Which of the following is not one of the age structure categories?

"The maximum population of a given species that a particular habitat can sustain indefinitely without being degraded" is the definition of

At the present time the global human population approaches 7 billion persons.If we exceed the carrying capacity of the earth, the human population may suffer a substantial collapse.Given the following formula for population change: Population change = (births + immigration) ─ (deaths + immigration) What will be required of humans in order to stabilize or reduce our population?

A group of interbreeding individuals of the same species in the same geographic region is called a(n)

The non-poisonous ____ butterfly gains protection by looking like the bad-tasting ____ butterfly, which is a protective device known as ____.

If multiple species find themselves competing for the same resource, the competition can be reduced by which of the following?

Organisms with clumped distribution are fairly rare.

Succession leads inevitably toward an ideally adapted climax plant community or ecosystem.

-Observe the Figure above.Notice that in the upper graph the two species overlap.That region of niche overlap places the species in competition for the shared resource.Explain why this is not useful and how the niches of the two species have come to be separated as shown in the lower graph.

Parasites

If the resilience of a damaged area is low enough, the degraded area may not be restored by secondary succession. When this happens, the damaged area has reached

Scientists have changed their view about a stable type of climax community as the end product of succession and are now suggesting we can not predict the course of succession.

Use the Figure above to answer the following question(s). -Choose the portion of the graph that represents the number of reindeer that exceeded the capacity of their environment.
