Biodiversity

• What does the Index of Diversity measure?

  Biodiversity, species richness, and abundance
• What does a higher index of diversity indicate?

  Greater biodiversity and even species distribution
• What is the purpose of sampling in ecology?

  To draw conclusions about a whole population
• How can you avoid bias when sampling?

  Use random sampling methods
• What is a method to ensure sampling reliability?

  Use a large sample size and standardised methods
• What should you do with data from quadrats?

  Calculate mean and estimate population size
• Why are statistical tests like the t-test used?

  To check for significant differences between data sets
• How can farming reduce biodiversity?

  By removing habitats and using pesticides
• What are some ways farming can increase biodiversity?

  Adding hedgerows and using eco-friendly methods
• What are the effects of removing hedgerows in farming?

  • Fewer habitats for wildlife
  • Disruption of food chains
  • Reduced biodiversity
• What eco-friendly methods can farmers use to increase biodiversity?

  • Adding hedgerows
  • Sustainable farming practices
  • Applying for grants for eco-friendly initiatives
• Species richness- The number of different species in a community.
• Abundance- The number of invividuals in a species.
• Habitat- The area where a species lives
• Community- All the populations of all the species in a habitat
• Biodiversity- The variety of living organisms in an area.
