Questions and Answers
  • 1. 

    Which of the following ways can flowering plants pollinate?

    • A.

      Wind

    • B.

      Birds

    • C.

      Mammals and insects

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    Flowering plants can pollinate through various means, including wind, birds, mammals, and insects. Wind pollination occurs when the plant releases lightweight pollen grains into the air, which are carried by the wind to other flowers for fertilization. Birds can pollinate plants by feeding on nectar and inadvertently transferring pollen between flowers. Similarly, mammals, such as bats and rodents, can also carry pollen while feeding on flowers. Insects, including bees, butterflies, and beetles, are the most common pollinators for flowering plants, as they actively seek nectar and inadvertently transfer pollen between flowers. Therefore, all of the mentioned ways are valid methods of pollination for flowering plants.

    During this interaction, one participant benefits while the other is unaffected.

    • A.

      Mutualism

    • B.

      Commensalism

    • C.

      Predator-prey/parasite-host

    • D.

      Ammensalism

    Correct Answer
    B. Commensalism
    Explanation
    Commensalism is the correct answer because it refers to a type of symbiotic relationship where one participant benefits while the other is unaffected. In commensalism, one organism benefits from the interaction, while the other is neither harmed nor helped. This is different from mutualism, where both participants benefit, and predator-prey/parasite-host relationships, where one organism benefits at the expense of the other. Ammensalism, on the other hand, refers to a type of relationship where one organism is harmed while the other is unaffected.

    Rate this question:

  • 6. 

    During this type of interaction, both participants are beneficial.

    • A.

      Commensalism

    • B.

      Ammensalism

    • C.

      Mutualism

    • D.

      Parasitism

    Correct Answer
    C. Mutualism
    Explanation
    Mutualism is the correct answer because it describes a type of interaction where both participants benefit. In mutualistic relationships, both organisms gain something from the interaction, such as food, protection, or transportation. This type of interaction is different from commensalism, where one organism benefits and the other is unaffected, and from parasitism, where one organism benefits at the expense of the other. Amensalism, on the other hand, describes a relationship where one organism is harmed while the other is unaffected.

    Rate this question:

  • 7. 

    Which interaction is involved when one species has a negative effect on another, but the reverse effect is negligible.

    • A.

      Commensalism

    • B.

      Mutualism

    • C.

      Predator-prey/parasite-host

    • D.

      Ammensalism

    Correct Answer
    D. Ammensalism
    Explanation
    Ammensalism is the correct answer because it refers to a type of interaction where one species has a negative effect on another species, but the reverse effect is negligible. In ammensalism, one species is unaffected by the presence of the other species, while the other species is negatively impacted. This is different from commensalism, where one species benefits and the other is unaffected, and mutualism, where both species benefit. Predator-prey/parasite-host interactions involve both species having an effect on each other, while ammensalism only involves one species having a negative effect on the other.

    Rate this question:

  • 8. 

    One organism may benefit itself while harming another organism. What is the name of this interaction?

    • A.

      Commensalism

    • B.

      Predator-prey/parasite-host

    • C.

      Ammensalism

    • D.

      Mutualism

    Correct Answer
    B. Predator-prey/parasite-host
    Explanation
    The correct answer is predator-prey/parasite-host. In this type of interaction, one organism (predator or parasite) benefits by feeding on or using another organism (prey or host) for resources, while the other organism is harmed or negatively affected. This interaction is common in nature and plays a crucial role in regulating populations and maintaining ecological balance.
