  • Q6
    If a disruption were to be caused in an ecosystem, which would be the most detrimental?
    Removing invasive species from an ecosystem to preserve the native species population.
    Strategically removing trees to clear up overpopulation in ecosystems.
    Burning a yard during the winter so that grass grows back healthier during the following summer.
    Introduction of an invasive species such as large snakes in Florida

  • Q7
    During PRIMARY succession, what would cause the most common factor in creating a new ecosystem?
    An area that has already been previously established with soil so that shrubs and trees can grow back.
    Somewhere similar to a back yard that has been burned so the grass can grow back greener.
    Some area that has already been established with plants so that smaller invertebrate animals can now create a habitat.
    some type of solid ground such as the side of a mountain or a rock that lichen or some other organism can grow on to establish soil.

  • Q8
    When the graph above is approaching the transitional phase, what is happening with respect to the population?
    Question Image
    The population growth is slowing down because it is approaching its carrying capacity (titled plateau phase)

  • Q9
    If a population of deer are present in an ecosystem and have a mutualistic relationship with foxes. This relationship is one that the deer depend on for survival. If the fox population were to be wiped out by an increase in a bear population what would be the most common result for the deer population?
    The deer population would decrease and possibly go extinct because it relied on the fox population for survival. Without this relationship the deer would decrease either due to a lack of help from the fox or an increase in predation from the bear.

  • Q10
    Consider a population that has survived for thousands of years. In this ecosystem there is a population of red tailed foxes that have coexisted with other populations in the forest. The past few years there has been a new species of blue tailed foxes that hunt the same animals as the white tailed foxes. The blue tailed foxes are not genetically superior to the red tailed foxes in anyway. What do you expect to happen to the population of both foxes and the populations of the animals that they hunt?
    The population of both fox species will remain constant, however, the resources that both fox populations hunt will decrease dramatically due to both species feeding on them.

  • Q11
    What is the role of bacteria in the soil for plants?
    to fixate oxygen
    to fixate phosphorus
    To fixate the nitrogen
    To fixate carbon

  • Q12
    If there was once previously a population of brown bears in an ecosystem that ate fish for their primary diet and a new black bear population was introduced, what would you expect to be the IMMEDIATE outcome of the bear and fish populations?
    The population of the fish would increase due to the amount of black and brown bears finding a different prey
    The bear populations would increase due to their being a new species virtually doubling the population and the fish population would decrease due to the increased number of predators.
    The populations would not be affected
    The population of bear would decrease due to one species of bear leaving and the fish population would increase due to finding a new habitat

  • Q13
    During the two stages of succession (primary and secondary) when would you expect to have the greatest biodiversity?
    An ecosystem that is beginning secondary succession that is just developing complex plants
    An ecosystem that finishing secondary succession that is closing in on a climax community
    An ecosystem that has already undergone primary succession but is now cleared and has nothing grown back for secondary succession.
    An ecosystem that is just beginning primary succession where there are very simple organisms.

  • Q14
    If a tropical rainforest is a stable climax community and a storm passes through the ecosystem and knocks down a group of trees blocking a river flowing through the rainforest, what might you expect to happen during a very rainy season?
    The trees will not block the river flow so there is no need to worry
    The trees will fall but will not harm the river flow because the water will move the trees downstream
    Flooding will occur in the rainforest due to the blockage of the river flow
    If a tree falls in the woods, would anybody hear it?
