Question 3

Question

Answer
  • True
  • False

Question 4

Question
What are the impacts of Agriculture on Biodiversity?
Answer
  • Farmers select more productive crops so the gene pool is reduced
  • Woodland clearance to increase farmland area allows new species to live in the new habitat, increasing the diversity
  • Pesticides remove unwanted pests, reducing the number of species
  • Monoculture of crops allows a greater number of different species to live in one area
