Quick student answer

Which of the following farming techniques is most likely to reduce biodiversity in a community?

Direct answer

Monoculture is the practice of growing a single crop species over a wide area for consecutive seasons, which significantly reduces habitat diversity and the variety of species present.

Key terms

  • Biodiversity: The variety of life in a particular habitat or ecosystem, including the number of species, genetic diversity, and ecosystem diversity.
  • Ecosystem services: The benefits that humans derive from ecosystems, including provisioning, regulating, cultural, and supporting services.

Common trap

Confusing biodiversity with species richness: Biodiversity encompasses not only species richness but also genetic diversity and ecosystem diversity.
