  • Question 1
    60 seconds
    Q. A drought has hit this grassland biome. How will this effect the rabbit population?
    answer choices
    The rabbits will increase in number.
    The rabbit population will stay the same.
    The rabbit population will decrease.
    The rabbit population will become extinct immediately.
  • Question 2
    60 seconds
    Q.

    Which of the following most likely supports the most sustainable ecosystem?

    answer choices

    The habitat with the greater number of green plants

    The habitat with the greatest variety of living things

    The habitat with the warmest average temperature

    The habitat with the greatest number of consumers

  • Question 3
    60 seconds
    Q.

    Which of the following contributes most to promoting sustainability in an ecosystem?

    answer choices

    Lack of decomposers

    A balanced water table

    Variety of organisms

    A narrow temperature range

  • Question 4
    30 seconds
    Q.

    Which factor will negatively affect biodiversity?

    answer choices

    All of the above

  • Question 5
    30 seconds
    Q.

    Which factor is least likely to determine the biodiversity of an area?

    answer choices

    Amount of Wind

    Average Temperature

    Rainfall amount

    Soil Type

  • Question 6
    60 seconds
    Q. Why is biodiversity important in fighting disease in food crops?
    answer choices
    It prevents one disease from wiping out an entire food crop.
    It prevents habitat loss of native species.
    It provides different foods for different populations.
    It prevents fungal disease from wiping out corn crops.
  • Question 7
    60 seconds
    Q. Why is biodiversity so important?
    answer choices
    Because all species depend on each other to survive, so if one becomes extinct another species that relies on it could go extinct as well
    Because it’s better to have only one variation of each species.
    Because it better to only have a few species on Earth.
    Honestly, I have no idea what biodiversity is!
  • Question 8
    60 seconds
    Q.

    Elephant are considered an important species in east Africa. During droughts, they dig deep holes in dry riverbeds, and the holes fill up with water. These holes are then used by all other animals in the area. Which of the following most accurately describes how the loss of elephants would affect this ecosystem?

    answer choices

    Biodiversity would increase, as more species evolved.

    Biodiversity would remain the same, but population sizes would increase.

    Biodiversity would decrease, since few species could tolerate living with less available water.

    Biodiversity would not change, although there would be increased predation by lions.

  • Question 9
    60 seconds
    Q.

    Zebra mussels were first discovered in the Great Lakes thirty years ago and have since spread to lakes throughout the region. Zebra mussels reproduce quickly and have few natural predators.

    What will most likely happen to other native mussel species in the Great Lakes region?

    answer choices

    Native species will begin to interbreed with zebra mussels.

    Native species populations will decrease in areas with large zebra mussel populations.

    Individuals of the native species will mutate to become more sililar to zebra mussels.

    Individuals of the native species will mutate to become less similar to zebra mussels/.

  • Question 10
    60 seconds
    Q.

    Which of these relationships is most correct?

    answer choices

    High Biodiversity leads to Low Sustainability

    Low Biodiversity leads to High Sustainability

    High Biodiversity leads to High Sustainability

    Biodiversity and Sustainability are not related

  • Question 11
    60 seconds
    Q.

    Deer are introduced into a grassland ecosystem and their population increases considerably. If the deer population continues to grow, which is the MOST likely outcome for the ecosystem?

    answer choices

    Biodiversity would increase, and sustainability would decrease

    Biodiversity would increase, and sustainability would increase

    Biodiversity would decrease, and sustainability would increase

    Biodiversity would decrease, and sustainability would decrease

  • Question 12
    60 seconds
    Q.

    Which of these is a threat to the survival of an ecosystem?

    answer choices

    Competition among some consumer populations

    Less biomass at higher levels of the food web

    A shrinking variety of animal and plant species

    Predator-prey population cycles

  • Question 13
    45 seconds
    Q.

    Why is a reduction in biodiversity due to loss of plant populations especially destructive to an ecosystem?

    answer choices

    Plants are primary producers

    Plans have the most biomass

    Plants are resistant to disease

    Plants are part of the food web

  • Question 14
    45 seconds
    Q.

    Which of these explains why an

    ecosystem is healthy when it has a variety of species?

    answer choices

    An increased number of species allows for fewer food chains

    A larger number of species reduces competition for abiotic resources

    An increased number of species contributes to greater chances for adaptability

    A larger number of species allows for greater diversity in interdependence
