Questions and Answers

What does biological control involve?

  • The use of chemical pesticides to reduce population density
  • The direct intervention of humans to control population density
  • The genetic modification of organisms to control their population
  • The action of natural enemies in maintaining another organism's density to a lower level (correct)

    • Which organisms are involved in biological control?

  • Decomposers and scavengers
  • Parasites, predators, and pathogens (correct)
  • Herbivores and omnivores
  • Photosynthetic organisms

    • What is the goal of biological control?

  • Increasing population density of organisms
  • Maintaining another organism's density to a lower level than would occur in their absence (correct)
  • Promoting the use of chemical pesticides
  • Introducing new species to an ecosystem

    Study Notes

    Biological Control

    • Biological control involves the use of living organisms to control or manage pest populations, reducing the need for chemical pesticides.
    • The organisms involved in biological control are predators, parasitoids, and pathogens that attack or infect pests.

    Goals and Types of Biological Control

    • The goal of biological control is to regulate pest populations, maintaining a balance between the pest and its natural enemies.
    • There are two main types of biological control: Natural Biological Control and Applied Biological Control.

    Natural Biological Control

    • Natural Biological Control occurs naturally, without human intervention, and relies on the primary role of natural enemies to regulate pest populations.
    • Natural enemies, such as predators, parasitoids, and pathogens, play a crucial role in controlling pest populations in a natural ecosystem.

    Applied Biological Control

    • Applied Biological Control involves the intentional introduction of natural enemies to a new area, or the augmentation of existing natural enemies, to control pest populations.
    • The main difference between Applied Biological Control and Natural Biological Control is the level of human intervention, with Applied Biological Control requiring human action to introduce or augment natural enemies.
    • Applied Biological Control can be used to accelerate the process of natural control, or to establish a new equilibrium between the pest and its natural enemies.
