Evidence shows that some grasses benefit from being grazed. Which of the following
terms would best describe this plant-herbivore interaction?
competition
predation
commensalism
parasitism
mutualism - Answer-mutualism
Which statement best describes the evolutionary significance of mutualism?
Mutualistic interaction lessens competition in communities where it is present.
Interaction increases the survival and reproductive rates of mutualistic species.
Individuals partaking in a mutualistic relationship are more resistant to parasites.
Mutualism offers more biodiversity to a community.
Mutualistic relationships allow organisms to synthesize and use energy more efficiently.
- Answer-Interaction increases the survival and reproductive rates of mutualistic
species.
How might an ecologist test whether a species is occupying all of its fundamental niche
or only a portion of it?
Observe if the niche size changes after the addition of nutritional resources to the
habitat.
Observe if the niche size changes after the introduction of a similar non-native species.
Study the temperature range and humidity requirements of the species.
Observe if the species expands its range after the removal of a competitor.
Measure the change in reproductive success when the species is subjected to
environmental stress. - Answer-Observe if the species expands its range after the
removal of a competitor.
, Why are food chains relatively short?
Longer chains are less stable and energy transfer between levels is inefficient.
Food chain length is ultimately determined by the photosynthetic efficiency of
producers.
There are only so many organisms that are adapted to feed on other types of
organisms.
Top-level feeders tend to be more numerous than lower-trophic-level species.
Top-level feeders tend to be small but are capable of conserving more energy. -
Answer-Longer chains are less stable and energy transfer between levels is inefficient.
