The Nutrient Cycle Quiz: Trivia! - Quiz


What do you know about the nutrient cycle? Nutrient cycling is an essential process in an ecosystem. In the nutrient cycle, the usage of nutrients in their environment, their movement, and their recycling processes are described. Vital nutrients include carbon, oxygen, hydrogen, phosphorus, and nitrogen, are necessary to be recycled for the existence of organisms. This quiz illustrates the nutrient cycle and why it is crucial to the health of an ecosystem.


Questions and Answers
  • 1. 

    In a nutrient cycle, nutrients are:

    • A.

      Recycled constantly

    • B.

      Put in long term storage occasionally in nutrient "sinks"

    • C.

      Put in temporary storage in the bodies of organisms

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    In a nutrient cycle, nutrients undergo a continuous process of recycling. They are not permanently lost but rather reused and circulated within the ecosystem. Additionally, nutrients can be stored for extended periods in nutrient "sinks" such as soil, sediments, or bodies of water. This storage allows for the availability of nutrients when needed. Furthermore, nutrients are also temporarily stored in the bodies of organisms as they consume and utilize them for their metabolic processes. Therefore, all of the given options accurately describe the fate of nutrients in a nutrient cycle.

    A nutrient cycle reservoir is a place where:

    • A.

      The nutrient is stored for a long time

    • B.

      The nutrient is stored for a short time

    • C.

      The nutrient is stored forever

    • D.

      Can be A or B

    Correct Answer
    D. Can be A or B
    Explanation
    A nutrient cycle reservoir can be a place where the nutrient is stored for a long time or for a short time. This means that it can either be a long-term storage site or a temporary storage site depending on the specific nutrient and the cycle it is a part of. The duration of storage will vary depending on factors such as the type of nutrient, the environmental conditions, and the organisms involved in the cycle. Therefore, the nutrient cycle reservoir can be either A (stored for a long time) or B (stored for a short time).

    Eutrophication is the situation where:

    • A.

      A water body is made really nice with extra nutrients

    • B.

      A water body is destroyed by excess nutrients like nitrogen or phosphorus

    • C.

      A piece of land is over fertilized

    • D.

      The atmospheric reservoir receives too much carbon and it traps more heat

    Correct Answer
    B. A water body is destroyed by excess nutrients like nitrogen or phosphorus
    Explanation
    Eutrophication is the situation where a water body is destroyed by excess nutrients like nitrogen or phosphorus. When these nutrients enter a water body in excessive amounts, they cause an overgrowth of algae and other aquatic plants. This excessive growth depletes the oxygen levels in the water, leading to the death of fish and other aquatic organisms. The water body becomes polluted and its ecosystem is disrupted, resulting in the destruction of the water body.

    The Enhanced Greenhouse Effect is a problem that occurs when:

    • A.

      A water body is destroyed by excess nutrients like nitrogen or phosphorus

    • B.

      A piece of land is over fertilized

    • C.

      A greenhouse plant receives too much fertilizer

    • D.

      The atmospheric reservoir receives too much carbon and it traps more heat

    Correct Answer
    D. The atmospheric reservoir receives too much carbon and it traps more heat
    Explanation
    The Enhanced Greenhouse Effect is a problem that occurs when the atmospheric reservoir receives too much carbon and it traps more heat. This leads to an increase in the Earth's overall temperature, causing climate change and various negative impacts on the environment. The excessive carbon in the atmosphere acts as a blanket, preventing heat from escaping back into space and causing the planet to warm up. This phenomenon is a major concern as it disrupts ecosystems, melts polar ice caps, and contributes to extreme weather events.

    The following are a part of the nitrogen cycle:

    • A.

      Photosynthesis turns CO2 into sugar

    • B.

      Respiration turns sugar into CO2

    • C.

      Urine animal waste is recycled by bacteria to form nitrites and nitrates.

    • D.

      Nitrogen-fixing bacteria fix atmospheric nitrogen gas to oxygen to form nitrates.

    • E.

      C and D

    • F.

      A and B

    Correct Answer
    E. C and D
    Explanation
    The correct answer is C and D. This is because urine animal waste is recycled by bacteria to form nitrites and nitrates, which is a part of the nitrogen cycle. Additionally, nitrogen-fixing bacteria fix atmospheric nitrogen gas to oxygen to form nitrates, which is also a part of the nitrogen cycle.

    The following are a part of the carbon cycle.

    • A.

       Nitrogen fixing bacteria fix atmospheric nitrogen gas to oxygen to form nitrates.

    • B.

      Respiration turns sugar into CO2

    • C.

      Eutrophication results from excess fertilizer

    • D.

      Photosynthesis turns CO2 into sugar

    • E.

      B and D

    • F.

      A and C

    Correct Answer
    E. B and D
    Explanation
    The correct answer is B and D. Nitrogen fixing bacteria play a role in the carbon cycle by converting atmospheric nitrogen gas into nitrates, which are then used by plants to produce organic compounds. This process is called nitrogen fixation. On the other hand, photosynthesis is the process by which plants convert carbon dioxide (CO2) into sugar, which is an important step in the carbon cycle. Therefore, both B and D are correct statements related to the carbon cycle.

    The term "Cycle" is used in Nutrient cycles because:

    • A.

      They have two parts like the two wheels of a "Bicycle"

    • B.

      Their steps always form a long ring, like a snake biting its tail

    • C.

      The nutrients always get cycled and recycled, through the many paths of the system.

    Correct Answer
    C. The nutrients always get cycled and recycled, through the many paths of the system.
    Explanation
    The term "Cycle" is used in Nutrient cycles because the nutrients always get cycled and recycled, through the many paths of the system. This means that the nutrients are continuously moving through different parts of the ecosystem, being taken up by organisms, released back into the environment, and then taken up again by other organisms. This constant cycling ensures that nutrients are available for all living organisms and helps maintain the balance of the ecosystem.

    What is nitrogen used for?

    • A.

      To make rain, sleet, and snow

    • B.

      To make proteins

    • C.

      To make living thing

    Correct Answer
    B. To make proteins
    Explanation
    Nitrogen is an essential element used by living organisms to make proteins. Proteins are large molecules made up of amino acids, and nitrogen is a crucial component of these amino acids. Without nitrogen, living things would not be able to synthesize proteins, which are involved in various biological processes such as growth, repair, and regulation of the body's tissues and organs. Therefore, nitrogen is used for the production of proteins in living organisms.

    Which process makes clouds?

    • A.

      Condensation

    • B.

      Precipitation

    • C.

      Evaporation

    • D.

      Runoff

    Correct Answer
    A. Condensation
    Explanation
    Condensation is the process that makes clouds. When water vapor in the air cools down, it condenses into tiny water droplets or ice crystals. These droplets or crystals then gather together to form clouds. Condensation occurs when warm, moist air rises and cools, causing the water vapor to change from a gas to a liquid or solid state. This process is essential for the formation of clouds, which play a crucial role in the Earth's water cycle and weather patterns.
