Exam 4: Biodiversity and Evolution

The size of the planet has significant influences that impact life on the planet.

The bird species known to forage in shrublands after they have experienced a wildfire are very different from the bird species that forage in shrublands that have not burned. a.In fact, the bird species foraging in burned shrublands are closely correlated with the age of the burn, or the number of years that have passed since the fire. A Certain birds forage at one-year post fire, different birds forage at three-years post fire, and so on.These birds could be called

Evidence for the history of life comes from

Clearly describe in what ways living organisms impact the climate of the planet.

How has the geological process of plate tectonics influenced the process of evolution over geologic time?

Match the items listed below with the appropriate choice -Which letter represents the species that can live in many places and eat many foods?

Most of the historic evidence that supports the scientific theory of evolution comes from ____________________.

When local environmental conditions change, background extinction can cause loss of species.

Clearly explain how large-scale mass extinctions can actually lead to evolutionary opportunities.

Genes mutate, ____________________ are selected, and populations____________________.

Match the type of diversity with the proper choice below. -Areas with both mountain ranges and coastal ecosystems have high diversity.

Which of the following best describes an organism's habitat?

Biological evolution is the process by which the genetic composition of a(n) ____________________ changes over time.

Living organisms in the biosphere help to influence the climate and the temperature of the planet.

Match the items listed below with the appropriate choice -Which letter represents the species most likely to become threatened or endangered?

A 2,000 acre coniferous forest in British Columbia has 8 species of coniferous trees. Over 100,000 individuals of each species have been counted by forest managers.A 2,300 acre temperate rain forest in the State of Washington has 12 species of trees, with about 75,000 to 80,000 individuals noted in each species.A similar sized tropical forest in Costa Rica is known to have over 5,000 species of trees. a.Biologists have counted between 3 and 100 individuals within each species.A Sonoran desert area in Baja California has 150 species of cactus with a range of 5 to 200 individuals counted in each species. -Which forest or community has the greater species richness?

-How does the bird labeled E compare with the birds labeled A, B, C, and D?

Which of the following is not true of the process of biological extinction?

In a population of wild bees, a mutation resulted in slightly larger wingspan in some of the bees. This larger wingspan made the bees more efficient in their flights to flowers to collect nectar. Thus, these bees became more successful. This trait was passed on to offspring, and eventually the larger wingspan variety of bee replaced their smaller-winged relatives completely. -Since the mutation produced a specific wing trait that was passed on, the mutation must have occurred
