Questions and Answers
  • 1. 

    Organisms are able to get ___________ from food

    • A.

      Characteristics

    • B.

      Evolution

    • C.

      Homeostasis

    • D.

      Energy

    Correct Answer
    D. Energy
    Explanation
    Organisms are able to get energy from food. Energy is a fundamental requirement for all living organisms to carry out their metabolic processes, maintain homeostasis, and perform various functions necessary for survival. Through the process of cellular respiration, organisms break down the organic molecules present in food and convert them into usable energy in the form of ATP (adenosine triphosphate). This energy is then utilized by the organism to perform essential functions such as growth, reproduction, movement, and maintaining bodily functions. Without energy from food, organisms would not be able to sustain life.

    _____________ is a set of steps that is followed to test a hypothesis and collect data

    • A.

      A species

    • B.

      An omnivore

    • C.

      An experiment

    Correct Answer
    C. An experiment
    Explanation
    An experiment is a set of steps that is followed to test a hypothesis and collect data. This involves designing and carrying out controlled procedures to investigate a specific phenomenon or answer a research question. By manipulating variables and measuring their effects, experiments allow scientists to gather empirical evidence and draw conclusions about the relationship between cause and effect. Experiments are crucial in the scientific method as they provide a systematic approach to testing hypotheses and generating reliable data for analysis and interpretation.

  • 3. 

    Which of these organisms uses light energy to manufacture food for itself?

    • A.

      A heterotroph

    • B.

      An autotroph

    • C.

      An omnivore

    • D.

      A carnivore

    Correct Answer
    B. An autotroph
    Explanation
    An autotroph is an organism that can produce its own food using light energy. Autotrophs, such as plants and some bacteria, undergo photosynthesis to convert sunlight into chemical energy in the form of glucose. This process allows them to manufacture their own food and sustain themselves. Heterotrophs, on the other hand, cannot produce their own food and rely on consuming other organisms for nutrition. Omnivores and carnivores are examples of heterotrophs that obtain their energy by consuming other organisms.

    Rate this question:

  • 4. 

    The air in our atmosphere contains 78% of which of the following?

    • A.

      Phosphorus

    • B.

      Carbon

    • C.

      Nitrogen

    • D.

      Calcium

    Correct Answer
    C. Nitrogen
    Explanation
    The air in our atmosphere contains 78% nitrogen. Nitrogen is the most abundant gas in the Earth's atmosphere and plays a crucial role in various biological and chemical processes. It is an essential component of proteins and nucleic acids, which are the building blocks of life. Nitrogen is also important for plant growth as it is a vital nutrient for plants. Additionally, nitrogen gas helps to maintain the overall balance and composition of the atmosphere.

    Rate this question:

  • 5. 

    Rabbits, elephants and squirrels are examples of ____________

    • A.

      Carnivores

    • B.

      Herbivores

    • C.

      Omnivores

    Correct Answer
    B. Herbivores
    Explanation
    Rabbits, elephants, and squirrels are examples of herbivores because they primarily consume plant-based diets. Carnivores are animals that eat other animals, while omnivores have a diet that includes both plants and animals. However, rabbits, elephants, and squirrels are known for their preference for vegetation, making them herbivores.

    Rate this question:

  • 6. 

    Which marine biome is characterized by deep water depths that never receive sunlight?

    • A.

      A bog

    • B.

      A lake

    • C.

      An estuary

    • D.

      An aphotic zone

    Correct Answer
    D. An aphotic zone
    Explanation
    The correct answer is an aphotic zone. The aphotic zone is a marine biome characterized by deep water depths that never receive sunlight. This lack of sunlight prevents photosynthesis from occurring, resulting in a low level of primary productivity. The aphotic zone is typically found in the deeper parts of the ocean where sunlight cannot penetrate, and organisms in this biome have adapted to survive in the absence of light.

    Rate this question:

  • 7. 

    When the last member of a particular species dies, it is said to be _____________

    • A.

      Extinct

    • B.

      Endangered

    • C.

      Isolated

    • D.

      Diversified

    Correct Answer
    A. Extinct
    Explanation
    When the last member of a particular species dies, it is said to be extinct. Extinction occurs when a species no longer has any living individuals and is completely wiped out. This can happen due to various reasons such as habitat destruction, overhunting, or natural disasters. Once a species becomes extinct, it is gone forever and cannot be revived. The extinction of a species is a significant loss to biodiversity and can have far-reaching ecological consequences.

    Rate this question:

  • 8. 

    Which of these is not usually considered a threat to biodiversity?

    • A.

      Pollution

    • B.

      Use of pesticides

    • C.

      Acid precipitation

    • D.

      Preservation of habitats

    Correct Answer
    D. Preservation of habitats
    Explanation
    Preservation of habitats is not usually considered a threat to biodiversity because it involves protecting and conserving natural habitats, which in turn helps to maintain and support diverse ecosystems and the species that depend on them. By preserving habitats, we can ensure that species have suitable environments to live and thrive in, which ultimately promotes biodiversity. On the other hand, pollution, use of pesticides, and acid precipitation are all known to have negative impacts on biodiversity as they can harm and disrupt ecosystems, leading to the decline or loss of species.
