The species with the greatest chance of going extinct would be "a species with a slow reproduction rate and very little genetic variation living in a changing environment."
This is because:
- A slow reproduction rate means the species cannot quickly increase its population size to recover from declines.
- Very little genetic variation reduces the species' ability to adapt to environmental changes, making it more vulnerable to extinction.
- Living in a changing environment adds additional stress, as the species may not be able to cope and survive in the face of rapid ecological shifts.
These factors combined make it particularly likely for this species to go extinct.
