Global warming threatens the survival of Arctic foxes. Which of the following factors could be involved?
I. Competition with other fox species spreading north
II. Reduction in numbers of prey species of Arctic foxes
III. Decrease in oxygen availability to Arctic foxes
I only I only
B. I and II only
C. II and III only
D. I, II and III



Answer :

The correct answer is B.

Global warming encourages other fox species to spread into areas previously unsuited to them.  This increase in fox populations, and also change in environment, will reduce the amount of prey available in the area.

Oxygen availability will not be impacted enough to cause the arctic foxes to suffocate.  If it did, humans would be at risk too!
