Apes Midterm Review

Which of the following species is most likely to be an invasive species if introduced into a favorable new habitat?

A

Which of the following best explains why terrestrial trophic pyramids usually do not have levels higher than tertiary consumers?

A large proportion of energy is lost as heat as it is transferred up the pyramid, so there is not enough energy available to support another level.

Which of the following statements about levels of biodiversity is correct?

A population with high genetic biodiversity is better able to respond to environmental stressors.

Highly specialized species tend to evolve on islands because of the environmental conditions and resource availability.Based on the theory of island biogeography, which of the following would most likely experience the greatest decline of specialist species if an invasive species emigrated from the mainland?

A small island in close proximity to the mainland

Which of the following explanations is best supported by the data shown in the map above?

Animals migrate seasonally to mate and to find food in different habitats.

Equal numbers different species increases what?

Biodiversity

This biome contains plants that are adapted to prevent water loss due to the low average rainfall and high temperatures year-round.

Desert

The table above shows the balanced chemical equations that represent three processes that are part of the nitrogen cycle. Which of the following is exemplified by the equations above?

Each biogeochemical cycle demonstrates the conservation of matter.

Which of the following best explains how environmental stressors, such as wildfires, can affect biodiversity in an ecosystem?

Ecosystems with more species diversity are more likely to recover after a disturbance than ecosystems with low species diversity.

Which of the following best describes the movement of energy in an ecosystem?

Energy is harnessed by producers, and available energy decreases with each trophic level transfer.

Scientists calculated the net primary productivity at two different forest sites. Both forests have the same gross primary productivity. Forest A has a net primary productivity of 1,650kcal/m2/year, and forest B has a net primary productivity of 1,110kcal/m2/year.

Forest A producers have lower rates of cellular respiration than forest B producers.

Which of the following best describes gross primary productivity in an ecosystem?

Gross primary productivity is the total amount of solar energy captured by producers through photosynthesis over time.

Which of the following best describes a symbiotic relationship?

Intestinal bacteria inhabit the gut of humans.

Cycads are gymnosperms that were diverse and abundant during the Mesozoic era. Extant species of cycads share many traits with those from the Mesozoic era. Cycads bear cones, are long-lived with slow growth rates, show late reproductive maturity, and have very few offspring. Based on this description, the cycads are

K-strategists with a Type I survivorship curve.

Which of the following best describes the net primary productivity of an ecosystem?

Net primary productivity is the amount of energy lost through respiration by producers subtracted from the gross primary productivity of an ecosystem.

The tropical rain forests are known to have a large variety of animals. One example is the orchid mantis that is highly camouflaged when standing on a certain species of orchid found in tropical environments. Another species, the tropical cockroach, can live anywhere in the rain forest where it can find water and a food source. Which of the following statements best describes why it is predicted that the orchid mantis will be more affected by global climate change than the tropical cockroach will be?

Orchid mantises tend to be advantaged in habitats that remain constant; the rain forest habitat is likely to shift because of global climate change.

The graph below shows data about three tree species after a glacial retreat.Based on the data shown in the graph, which of the following events occurred after the glacial retreat?

Primary succession

Five different species of warblers, seed-eating birds, live in the same species of conifer trees. All of the birds migrate to coniferous forests during the summer, and different species reside in different areas in the same tree. They feed on the seeds of the conifer trees, but the different species do not mate with each other. Which of the following best explains why the different warbler species can all have habitats in the same conifer trees?

Resource partitioning of the seeds reduces competition, and the five different species can live in the same tree.

This biome is characterized by long dry seasons and is dominated by grasses, shrubs, and grazing animals.

Savanna

In a fish species, the number of eggs that hatch and survive for one year varies depending on the number of eggs that were produced. As the number of eggs produced increases past a threshold number, the survival rate of the offspring decreases. Which of the following statements best explains why only a limited number of offspring can survive in a fish population?

The chance of survival decreases when there is intraspecific competition for resources among surviving yearlings.

A certain species of dinosaur laid large numbers of eggs, and the hatchlings had high mortality early in life. But if they survived, the young dinosaurs were able to grow at a rapid pace and disperse into the environment in order to thrive. Based on this information and the graph above, which of the following best characterizes this species of dinosaur?

The dinosaurs were r-strategists and exhibited a Type III survivorship curve

The graph below shows the change in sea level from the Cambrian period to today compared to today's sea level.Which of the following statements correctly describes the trends seen in the data?

The lowest sea level occurred during the Paleogene period.

A 163 square-kilometer (km2) small island is found 2,000km from the mainland. A second, larger, 230,000km2 island is found 1,000km from the mainland. Based on the theory of island biogeography, which of the following statements is most likely true about the small island when compared with the large island?

The rate of immigration is lower for the small island than for the large island.

Based on the theory of island biogeography, which of the following is the most likely reason that an island in the ocean that is 5 kilometers from a continent would have a higher number of species than one that is 15 kilometers from a continent?

There are more species that have the ability to travel 5 kilometers than can travel 15 kilometers.

This biome is warm and wet, with little seasonal variation in temperature and frequent precipitation.

Tropical rain forest

Which of the following species is most likely to provide extensive parental care to its offspring?
