- Select the correct statement(s) about the transfer of food energy up the trophic levels from its source in autotrophs.
Select all that apply.
Few plants have adaptations to reduce feeding by herbivores.
The length of a food chain is limited by the inefficiency of energy transfer along the chain.
An organism feeds at only one trophic level.
- According to the equilibrium model of island biogeography, species richness would be greatest on an island that is
small and remote.
large and close to a mainland.
small and close to a mainland.
large and remote.
- When climbing a mountain, we can observe transitions in biological communities that are analogous to the changes
in a community through different seasons.
in biomes at different latitudes.
in an ecosystem as it evolves over time.
at different depths in the ocean.
across the United States from east to west.
- Although many chimpanzees live in environments containing oil palm nuts, members of only a few populations use stones to crack open the nuts. The likely explanation is that
members of different populations have different nutritional requirements.
the cultural tradition of using stones to crack nuts has arisen in only some populations.
members of different populations differ in manual dexterity.
the behavioral difference is caused by genetic differences between populations.
members of different populations differ in learning ability.
- In mammals, the eardrum transmits sound waves to three small bones, which transmit the waves to fluid waves within the cochlea. Where are the three small bones located?
- a The length of a food chain is limited by the inefficiency of energy transfer along the chain
- b in biomes at different latitudes.
- c Middle ear
- d the cultural tradition of using stones to crack nuts has arisen in only some populations.

5 Multiple Choice Questions
- The perception of sensory input by humans and star-nosed moles differs.
The number and type of sensory receptors in humans and star-nosed moles differ.
- If a factor limits population growth, increasing its availability will increase population growth.
- restoration ecology.
- grows at its maximum per capita rate.
5 True/False Questions
The transduction of sound waves into action potentials takes place
within the middle ear as the vibrations are amplified by the malleus, incus, and stapes.
as the basilar membrane vibrates at different frequencies in response to the varying volume of sounds.
as the basilar membrane becomes more permeable to sodium ions and depolarizes, initiating an action potential in a sensory neuron.
within the tectorial membrane as it is stimulated by the hair cells.
when hair cells are bent against the tectorial membrane, causing them to depolarize and release neurotransmitter that stimulates sensory neurons. → two species that have exactly the same niche cannot coexist in a community.
Which lake zone would be absent in a very shallow lake?
benthic zone → aphotic zone
Which of the following would be considered an example of bioremediation?
reconfiguring the channel of a river
using a bulldozer to regrade a strip mine
adding seeds of a chromium-accumulating plant to soil contaminated by chromium
dredging a river bottom to remove contaminated sediments
adding nitrogen-fixing microorganisms to a degraded ecosystem to increase nitrogen availability → vegetation demonstrating vertical layering
WHAT IF? If the direction of Earth's rotation reversed, the most predictable effect would be
winds blowing from west to east along the equator.
a loss of seasonal variation at high latitudes.
no more night and day.
a big change in the length of the year.
the elimination of ocean currents. → winds blowing from west to east along the equator.
Scientific study of the population cycles of the snowshoe hare and its predator, the lynx, has revealed that
the hare population is r-selected and the lynx population is K-selected.
the prey population is controlled by predators alone.
both hare and lynx populations are regulated mainly by abiotic factors.
hares and lynx are so mutually dependent that each species cannot survive without the other.
multiple biotic and abiotic factors contribute to the cycling of the hare and lynx populations. → Changes in the behavior of cross-fostered young provide information about how the social and physical environment influences behavior.
Cross-fostering studies provide information about the relative importance of nature and nurture in the development of a trait.
