• C. It should be resistant to alien species invasions
• D. All of the above

Answer 1

Answer: (D)

A stable community is self-perpetuating and final biotic community that is in perfect harmony with the physical environment. Ecologists have explained the concept of a stable community using three of its principal characteristics:
a) it doesn't show an excessive amount of variation in productivity from year after year;
b) it must be either resistant or resilient to occasional disturbances (man-made or natural);
c) it must also be resistant to damage by alien species.
