Living Things Quizzes & Trivia

What do Year 8 students know about classification before the subject is taught?


Questions and Answers
  • 1. 

    A kangaroo is a mammal.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A kangaroo is a mammal because it possesses all the characteristics of mammals. It has hair or fur covering its body, gives birth to live young, and nurses its offspring with milk produced by mammary glands. Additionally, kangaroos are warm-blooded, have a four-chambered heart, and breathe air. These features classify them as mammals, making the statement "A kangaroo is a mammal" true.

    Spiders are insects.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Spiders are not insects. They belong to a different class of arthropods called arachnids. While both insects and spiders are arthropods, they have distinct characteristics that differentiate them. Insects have six legs, while spiders have eight. Additionally, spiders have two body segments (cephalothorax and abdomen) and do not have wings or antennae, which are common features of insects. Therefore, the statement "Spiders are insects" is false.

    Two animals are a different species if their types cannot inter-breed.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Two animals are considered to be a different species if they are unable to inter-breed. This means that if two animals belong to different species, their reproductive systems are not compatible and they cannot produce offspring together. Inter-breeding is a defining characteristic of species, and if animals cannot successfully reproduce with each other, it indicates that they are different species. Therefore, the statement is true.

    Dog breeds are different species.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Dog breeds are not different species, but rather different variations or types within the same species, Canis lupus familiaris. Breeds are created through selective breeding and have distinct physical and behavioral characteristics, but they can still interbreed and produce fertile offspring, which is a defining characteristic of being the same species.

    Rate this question:

  • 5. 

    Which of the following words are used to classify different species?

    • A.

      Kingdom

    • B.

      Breed

    • C.

      Class

    • D.

      Species

    • E.

      Type

    • F.

      Bacteria

    Correct Answer(s)
    A. Kingdom
    C. Class
    D. Species
    Explanation
    Different species are classified based on their characteristics and relationships. The classification system includes various levels, such as kingdom, class, and species. Kingdom is the highest level of classification, grouping organisms into broad categories based on their characteristics. Class is a lower level of classification, further dividing organisms within a kingdom based on shared characteristics. Species is the most specific level of classification, identifying individual organisms that can interbreed and produce fertile offspring. Breed, type, and bacteria are not used to classify different species.

    Which the following characteristics do mammals have?

    • A.

      Scales and gills

    • B.

      Hair and feed young milk

    • C.

      Eggs

    • D.

      Can't control body temperature

    Correct Answer
    B. Hair and feed young milk
    Explanation
    Mammals have the characteristic of having hair and being able to feed their young with milk. This is a defining feature of mammals, as no other group of animals possesses both of these traits. Hair helps mammals regulate body temperature and provides insulation, while milk is produced by mammary glands and provides essential nutrients to their offspring. The other options, such as scales and gills, eggs, and inability to control body temperature, are not characteristics of mammals.

  • 7. 

    Which the following characteristics do fish have?

    • A.

      Scales and gills

    • B.

      Give birth to live young

    • C.

      Legs

    • D.

      Hair

    Correct Answer
    A. Scales and gills
    Explanation
    Fish have scales and gills, which are two distinct characteristics that differentiate them from other animals. Scales provide protection and help with movement in water, while gills allow fish to extract oxygen from water for respiration. The option "Give birth to live young" is incorrect because most fish reproduce by laying eggs. Fish also do not have legs or hair, making those options incorrect as well.

    Which the following characteristics do insects have?

    • A.

      Scales and gills

    • B.

      Give birth to live young

    • C.

      Six legs

    • D.

      Feathers

    Correct Answer
    C. Six legs
    Explanation
    Insects have six legs. This is a defining characteristic of insects, as they are the only group of animals that have exactly six legs. Other characteristics listed, such as scales and gills, giving birth to live young, and feathers, are not traits that are typically associated with insects.

    Rate this question:

  • 9. 

    Which the following characteristics do birds have?

    • A.

      Scales and gills

    • B.

      Give birth to live young

    • C.

      Six legs

    • D.

      Feathers

    Correct Answer
    D. Feathers
    Explanation
    Birds have feathers. Feathers are unique to birds and serve several important functions such as insulation, flight, and display. Feathers provide insulation by trapping air close to the bird's body, keeping it warm. They also allow birds to fly by providing lift and controlling their movements in the air. Additionally, feathers are often used for courtship displays and to attract mates. Feathers are a defining characteristic of birds and are not found in any other animal group.

    Bacteria don't have parents they divide.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Bacteria reproduce through a process called binary fission, where they divide into two identical daughter cells. They do not have parents in the traditional sense of sexual reproduction, where offspring inherit genetic material from two parents. Instead, bacteria simply replicate their DNA and divide into two new cells, making the statement "Bacteria don't have parents, they divide" true.

  • 11. 

    Trees and mushrooms belong to different kingdoms (they are not related).

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Trees and mushrooms belong to different kingdoms because they have distinct characteristics and evolutionary histories. Trees belong to the kingdom Plantae, as they are multicellular organisms that undergo photosynthesis to obtain energy. On the other hand, mushrooms belong to the kingdom Fungi, as they are heterotrophic organisms that obtain nutrients by decomposing organic matter. These two groups have different cellular structures, reproductive methods, and ecological roles, indicating their separate evolutionary paths. Therefore, the statement that trees and mushrooms belong to different kingdoms is true.

    We use a classification system to describe living things to:

    • A.

      To divide them into smalleer groups

    • B.

      To organise them neatly

    • C.

      To relate what creatures are similar to other

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    The classification system is used to divide living things into smaller groups, organize them neatly, and relate creatures that are similar to each other. This system helps in categorizing and understanding the vast diversity of living organisms by grouping them based on their shared characteristics and relationships.
