Questions and Answers
  • 1. 

    What does Biotic Factor mean?

    • A.

      All living parts of an ecosystem.

    • B.

      All the nonliving parts of an ecosystem.

    • C.

      None of the above.

    Correct Answer
    A. All living parts of an ecosystem.
    Explanation
    Biotic factors refer to all living parts of an ecosystem. This includes plants, animals, fungi, and microorganisms that interact with each other and their environment. Biotic factors play a crucial role in shaping the structure and function of an ecosystem. They influence the availability of resources, energy flow, and the overall biodiversity within the ecosystem. Understanding biotic factors is essential for studying and managing ecosystems, as they contribute to the balance and stability of the natural environment.

    What does Abiotic Factor mean?

    • A.

      All the living parts of an ecosystem.

    • B.

      All the consumers of an ecosystem.

    • C.

      All the nonliving parts of an ecosystem.

    Correct Answer
    C. All the nonliving parts of an ecosystem.
    Explanation
    Abiotic factors refer to the nonliving components of an ecosystem, such as temperature, sunlight, soil, water, and air. These factors play a crucial role in shaping the environment and influencing the distribution and abundance of living organisms within the ecosystem. By understanding and studying abiotic factors, scientists can gain insight into how these physical and chemical conditions affect the overall health and functioning of an ecosystem.

    Rate this question:

  • 3. 

    A scientist that studies ecology is an:

    • A.

      Geographer

    • B.

      Ecologist

    • C.

      Janitor

    Correct Answer
    B. Ecologist
    Explanation
    An ecologist is the correct answer because ecology is the study of the relationships between organisms and their environment. A scientist who studies ecology would focus on understanding how organisms interact with each other and their surroundings, including the study of ecosystems, biodiversity, and the impact of human activities on the environment. A geographer studies the physical features of the Earth and its inhabitants, while a janitor is a person who cleans and maintains buildings.

  • 4. 

    Each ecosystem has a habitat.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    This statement is false because not every ecosystem has a habitat. While it is true that habitats are an important component of ecosystems, there are certain ecosystems, such as deep ocean ecosystems or barren deserts, where habitats may be absent or very limited. Therefore, it is not accurate to say that each ecosystem has a habitat.

    Rate this question:

  • 5. 

    Oxygen is an example of an Abiotic Factor.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Abiotic factors are non-living components of an ecosystem that can influence the survival and growth of organisms. Oxygen is considered an abiotic factor because it is not a living organism but is essential for the survival of most organisms. It is required for respiration, the process by which organisms obtain energy from food. Without oxygen, organisms would not be able to carry out cellular respiration and obtain the energy they need to survive. Therefore, oxygen is an example of an abiotic factor.

    Rate this question:

  • 6. 

    A group of organisms that can mate with each other and reproduce offspring that can also reproduce is called a

    Correct Answer
    species/ Species
    Explanation
    A group of organisms that can mate with each other and reproduce offspring that can also reproduce is called a species. This term refers to a population of individuals that share similar characteristics and can interbreed to produce fertile offspring. The concept of a species is fundamental in biology as it helps categorize and understand the diversity of life on Earth.

    Rate this question:

  • 7. 

    Humans, dogs, cats, and fish are examples of an

    Correct Answer
    organisms, animals
    Explanation
    Humans, dogs, cats, and fish are examples of "animals" or "organisms." They belong to the category of living creatures in the animal kingdom, and they represent various species within that kingdom. Each of these species has its own unique characteristics and traits but falls under the broader classification of animals.

    Rate this question:

  • 8. 

    What is natural selection in the context of evolution?

    • A.

      The deliberate breeding of organisms to achieve specific traits.

    • B.

      The process by which organisms adapt to their environment, with those possessing advantageous traits having a higher chance of survival and reproduction.

    • C.

      The sudden appearance of new species through mutations.

    • D.

      The process of genetic drift causing random changes in a population.

    Correct Answer
    B. The process by which organisms adapt to their environment, with those possessing advantageous traits having a higher chance of survival and reproduction.
    Explanation
    Natural selection is the process where organisms adapt to their environment. Individuals with advantageous traits that enhance their chances of survival and reproduction are more likely to pass on these traits to their offspring, leading to adaptation over time.
