  2. 4. the cycle of pesticide development followed by pest resistance, followed by development of a new pesticide.
  3. 5. used in areas with nutrient poor soils. It involves planting an area for a few years until the land is depleted of nutrients and then moving to another area and repeating the process.
  4. 6. industrial agriculture where labor is reduced, and machinery is used.
  5. 7. implies building homes for families of different economic levels next to one another in close proximity to their daily requirements.

  1. 1. some pesticides are found to build up over time in the fatty tissues of predators.
