Answer:
Option D, tightly linked
Explanation:
The population of both rabbit and Lynx is tightly linked which means that if the population of rabbit is affected negatively, the population of Lynx will also get affected negatively.
In general, Lynx gets its nutrition from rabbit by feeding on them when they are in sufficient number. When the rabbits become scarce, Lynx starts feeding on alternative food sources such as mice, carrion etc. but these food type cannot provide sufficient nourishment to the Lynx and hence the population of Lynx also reduces as some of them die because of starvation while the remaining move to different areas in search of food.
Hence, option D is correct
