Questions and Answers
  • 1. 

    Living things in the environment are called ______________________ factors, while non-living things are called ___________________ factors.

    • A.

      Abiotic and biotic

    • B.

      Biotic and abiotic

    • C.

      Nitrogen and carbon

    • D.

      Latitude and longitude

    Correct Answer
    B. Biotic and abiotic
    Explanation
    Living things in the environment are referred to as biotic factors, while non-living things are referred to as abiotic factors. Biotic factors include all living organisms such as plants, animals, fungi, and bacteria, which interact with each other and affect the ecosystem. Abiotic factors, on the other hand, include non-living components such as sunlight, temperature, water, air, soil, and minerals, which also play a crucial role in shaping the environment and influencing the distribution and abundance of organisms.

    Rate this question:

  • 2. 

    ____________________ is an abiotic factor.  

    • A.

      An animal

    • B.

      A plant

    • C.

      Soil

    • D.

      Bacteria

    Correct Answer
    C. Soil
    Explanation
    Soil is considered an abiotic factor because it is non-living and does not come from a living organism. It is a natural resource that consists of minerals, organic matter, water, and air. Soil plays a crucial role in supporting plant growth by providing nutrients, anchorage, and a medium for root development. It also acts as a habitat for various microorganisms and contributes to the overall ecosystem functioning.

  • 3. 

    If water is polluted, the _______________ could also be affected.

    • A.

      Soil

    • B.

      Air

    • C.

      Climate

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    If water is polluted, it can have a cascading effect on other elements of the environment. Polluted water can seep into the soil, contaminating it and making it unsuitable for agriculture or other purposes. It can also evaporate and contribute to air pollution, affecting the quality of the air we breathe. Additionally, polluted water can disrupt the natural balance of ecosystems, leading to changes in climate patterns. Therefore, all of the above options - soil, air, and climate - can be affected when water is polluted.

  • 4. 

    The ________________________ cycle involves evaporation, precipitation, and transpiration.

    • A.

      Nitrogen

    • B.

      Water

    • C.

      Carbon

    • D.

      Rock

    Correct Answer
    B. Water
    Explanation
    The water cycle involves the continuous movement of water on Earth through processes such as evaporation, precipitation, and transpiration. Water evaporates from bodies of water and land surfaces, forms clouds, and eventually falls back to Earth as precipitation. Transpiration is the process by which water is released from plants into the atmosphere. This cycle is crucial for the distribution and availability of water on Earth.

    Rate this question:

  • 5. 

    ________________________  is a biotic factor.  

    • A.

      The sun

    • B.

      A plant

    • C.

      Soil

    • D.

      Nitrogen

    Correct Answer
    B. A plant
    Explanation
    A plant is a biotic factor because it is a living organism that interacts with other living organisms in an ecosystem. Biotic factors are the living components of an ecosystem, including plants, animals, and microorganisms. They play a crucial role in the functioning of ecosystems and contribute to the overall biodiversity and balance of the ecosystem.

    Rate this question:

  • 6. 

    Before nitrogen can be used, it has to go through nitrogen _____________________, where the nitrogen atoms are separated.

    • A.

      Precipitation

    • B.

      Fertilization

    • C.

      Fixation

    • D.

      Elevation

    Correct Answer
    C. Fixation
    Explanation
    Nitrogen fixation is the process by which atmospheric nitrogen is converted into a usable form by certain bacteria. During this process, the nitrogen atoms are separated and combined with other elements to form compounds that can be used by plants and other organisms. This is necessary because atmospheric nitrogen is in a form that cannot be directly utilized by most organisms. Therefore, the correct answer is fixation.

    Rate this question:

  • 7. 

    Which of the following would not make soil more fertile (more able to grow crops)?

    • A.

      Animal waste

    • B.

      Chemicals

    • C.

      Fertilizer

    • D.

      Dead plants and animals

    Correct Answer
    B. Chemicals
    Explanation
    Chemicals would not make soil more fertile because they can have harmful effects on the soil's composition and nutrient balance. Chemicals such as pesticides and herbicides can kill beneficial microorganisms and insects that contribute to soil fertility. Additionally, excessive use of chemicals can lead to soil erosion and contamination, further degrading its fertility. Therefore, it is important to minimize the use of chemicals and opt for organic and sustainable farming practices to maintain and improve soil fertility.

    Rate this question:

  • 8. 

    Which action would add excess carbon to the environment?

    • A.

      Eating less meat

    • B.

      Recycling

    • C.

      Burning fossil fuels

    • D.

      Riding your bike

    Correct Answer
    C. Burning fossil fuels
    Explanation
    Burning fossil fuels would add excess carbon to the environment. Fossil fuels, such as coal, oil, and natural gas, contain carbon that has been stored underground for millions of years. When these fuels are burned for energy, carbon dioxide is released into the atmosphere, contributing to the greenhouse effect and climate change. This release of excess carbon into the environment is harmful and unsustainable.

    Rate this question:

  • 9. 

    Your human footprint is _______________________________.

    • A.

      Your impact on the environment

    • B.

      The size of your feet

    • C.

      How much you recycle

    • D.

      A never ending cycle in the environment

    Correct Answer
    A. Your impact on the environment
    Explanation
    The term "human footprint" refers to the impact that humans have on the environment. It encompasses various activities and practices that contribute to environmental degradation, such as pollution, deforestation, and resource depletion. By using the term "human footprint" to represent "your impact on the environment," the answer accurately reflects the concept of how human actions affect the natural world.
