  1. Using a computer model to generate possible outcomes
  2. Observing a fragmented prairie ecosystem
  3. Deforesting an ecosystem and observing the effects
  4. Hypothesizing about what might be possible outcomes of fragmentation
  5. Experirmenting on a small patch of trees in a controlled area

Effects of habitat fragmentation on forest ecosystem can be best studied in small and isolated populations. Prairie is a kind of dog. Prairie ecosystem is highly fragmented and effects of habitat fragmentation can't be studies easily in such fragmented ecosystems.
So, the correct answer is 'Observing a fragmented prairie ecosystem'.

Q5
Natural habitats that were once large and connected have become more fragmented due to human activities. Wildlife corridors between the fragments of habitat are necessary to maintain wildlife habitat and natural areas.
Which of these is a benefit of wildlife corridors?
