Two meadows each contain four recorded species. In Meadow A, individuals are distributed fairly evenly among the species; in Meadow B, most individuals belong to one species. Which conclusion is supported?

  1. A

    The site with more total individuals always has greater species richness.

  2. B

    The site where individuals are more evenly distributed among the four species has greater evenness.

  3. C

    The site with the rarest species has greater evenness, regardless of its other species.

  4. D

    The two sites must have identical evenness because they have the same richness.

A fishery wants to continue providing food over many years while reducing pressure on fish populations. Which approach best matches sustainable use?

  1. A

    Harvest as much as possible whenever demand is high.

  2. B

    Stop all use of biological resources in every location.

  3. C

    Set science-based limits and use responsible practices so resources can be used over time.

  4. D

    Use resources without monitoring because natural populations always recover.

A species is transported beyond its natural range and then harms native species in the new area. Which threat category best describes this situation?

  1. A

    A native species that becomes more abundant after a rainy season.

  2. B

    A species introduced beyond its natural range that harms native species or ecosystems.

  3. C

    A species that naturally migrates into a nearby habitat without causing harm.

  4. D

    A species that is rare in its native range but causes no ecological harm.

    Species richness

  2. B

    Ecosystem diversity

  3. C

    Species evenness

A landscape contains fragmented habitat, pollution affecting local species, and communities who depend on nearby biological resources. Propose a conservation plan that addresses each condition, explains how local communities should be involved, and describes how progress could be assessed and actions adjusted.

Two meadows each contain four species. In Meadow A, the species have similar numbers of individuals; in Meadow B, almost all individuals belong to one species. Which meadow has greater evenness?

  1. A

    The meadow with most individuals belonging to one species

  2. B

    The meadow with similar numbers of individuals in each species

  3. C

    Both meadows equally, because they have the same number of species

  4. D

    Neither meadow, because evenness depends only on habitat size

A population has substantial genetic variation. How might this variation help the population if environmental conditions change?

  1. A

    It ensures every individual can survive any environmental change.

  2. B

    It prevents environmental conditions from changing.

  3. C

    It can increase the chance that some individuals have traits suited to new conditions.

  4. D

    It makes all individuals in the population genetically identical.

Researchers want to compare species diversity in two habitats. Which approach makes the comparison most meaningful?

  1. A

    Use similar sampling methods, area, and effort in each habitat.

  2. B

    Sample one habitat much longer so its species list is more complete.

  3. C

    Compare only the habitats with the greatest number of recorded individuals.

  4. D

    Use different methods in each habitat to capture its unique conditions.

A road divides a habitat into isolated patches, while local temperatures are shifting. How can these pressures interact to affect a species?

  1. A

    Fragmentation prevents climate change from affecting local species.

  2. B

    Fragmentation can make it harder for species to move as climate conditions shift.

  3. C

    Climate change reconnects separated habitat patches by itself.

  4. D

    The two pressures cannot affect the same species at the same time.
