  1. 3. A community or communities plus the physical environment, interacting in a large, more or less self-contained area
  2. 5. The change in species composition, structure, or architecture through time
  3. 8. A place that is particularly appropriate for something, due to being very specific and different from others
  4. 9. The natural environment where an organism lives
  5. 10. The type of symbiosis in which one partner, the parasite, derives benefit from the other, the host
  6. 11. Autotrophs
