    Eutrophication is the increase in chemical nutrients often resulting in an explosion of primary producers and therefore hypoxic conditions.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Eutrophication refers to the excessive accumulation of nutrients in water bodies, such as nitrogen and phosphorus, which leads to an overgrowth of algae and other primary producers. This increase in primary producers can result in hypoxic conditions, where there is a lack of oxygen in the water due to the decomposition of the excessive plant material. Therefore, the statement that eutrophication often leads to hypoxic conditions is true.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Beavers have been observed to exhibit a free-running circadian activity rhythm under the ice in winter. This means that they maintain a consistent pattern of activity and rest throughout the day, even when they are living under the ice. This behavior is believed to be important for their survival and adaptation to the winter conditions.

    The Intermediate Disturbance Hypothesis states:

    • Animal abundance is greatest at an intermediate level of disturbance

    • Animal biomass is greatest at an intermediate level of disturbance

    • Species diversity is greatest at an intermediate level of disturbance

    • R-selected species dominate

    • K-selected species dominate

    Correct Answer
    A. Species diversity is greatest at an intermediate level of disturbance
    Explanation
    The Intermediate Disturbance Hypothesis suggests that species diversity is greatest at an intermediate level of disturbance. This means that when disturbance levels are too low, only a few dominant species may be able to thrive and outcompete others. On the other hand, when disturbance levels are too high, only a few highly adapted and resilient species may be able to survive. However, at an intermediate level of disturbance, a wider range of species can coexist, as there is a balance between competitive exclusion and the creation of new niches. This leads to a higher overall species diversity.

    A tropical rainforest is characterized by

    • Soils leached free of almost all nutrients

    • Huge trees and lush vegetation

    • Leaf-area index almost 2x that of an oak-hickory climax forest in North Carolina

    • All of the above

    • None of the above

    Correct Answer
    A. All of the above
    Explanation
    A tropical rainforest is characterized by soils that have been leached free of almost all nutrients, meaning that the soil lacks essential nutrients for plant growth. Additionally, tropical rainforests are known for their huge trees and lush vegetation, which thrive in the nutrient-rich environment provided by the dense forest floor. Finally, the leaf-area index of a tropical rainforest is almost twice that of an oak-hickory climax forest in North Carolina, indicating a higher density of leaves and vegetation in the rainforest. Therefore, all of the given statements accurately describe the characteristics of a tropical rainforest.

    Great Salt Lake, Utah is

    • A habitat for birds, brine shrimp.

    • The largest staging site for populations of Wilson's Phalarope

    • A stable system

    • All of the above

    • None of the above

    Correct Answer
    A. All of the above
    Explanation
    The Great Salt Lake in Utah is a diverse and unique ecosystem that supports a variety of habitats and species. It is a habitat for birds, providing an important stopover and nesting site for many migratory bird species. The lake is also home to brine shrimp, which are a vital food source for many bird species. Additionally, the lake is the largest staging site for populations of Wilson's Phalarope, a migratory bird species. The Great Salt Lake ecosystem is considered stable, as it has been able to support these habitats and species over time. Therefore, the correct answer is "all of the above."

    Infected animal that can transmit a disease but may be immune to it

    • Endemic

    • Infection

    • Vector

    • Pathogen

    • Carrier

    Correct Answer
    A. Carrier
    Explanation
    A carrier refers to an infected animal that can transmit a disease to others but may not show any symptoms or be immune to the disease themselves. This means that carriers can spread the infection to other individuals without suffering from the disease themselves. They act as a reservoir for the pathogen and play a significant role in the transmission of infectious diseases.

    Recovery of wood ducks in the Southeast involved which of the following:

    • Increased restrictions on hunting

    • More flooded woodlands concomitant with an increase in beaver populations

    • Wide-spread installation of next boxes

    • All of the above

    • None of the above

    Correct Answer
    A. All of the above
    Explanation
    The recovery of wood ducks in the Southeast involved all of the above options. Increased restrictions on hunting helped protect the wood duck population from overharvesting. More flooded woodlands, which were created by an increase in beaver populations, provided suitable habitat for wood ducks. The wide-spread installation of nest boxes also played a role in the recovery by providing additional nesting sites for wood ducks.

    A common theme for species that become extinct could involve:

    • Introduced species

    • Distribution confined to islands

    • Habitat loss

    • Over exploitation

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The correct answer is "all of the above" because all of the listed factors - introduced species, distribution confined to islands, habitat loss, and overexploitation - have been identified as common themes for species becoming extinct. Introduced species can disrupt ecosystems and outcompete native species, leading to their extinction. Species confined to islands are often more vulnerable to extinction due to their limited range and susceptibility to environmental changes. Habitat loss, caused by factors such as deforestation or urbanization, can destroy the homes and food sources of species. Overexploitation, such as hunting or fishing beyond sustainable levels, can also drive species to extinction.
