Which consequence results when an arctic fox cannot elevate metabolic rate sufficiently during extreme cold?

💡 Explanation

Insufficient metabolic rate prevents maintaining core temperature; thermogenesis relies partly on shivering which increases heat production. Therefore, inadequate rate causes insufficient shivering, rather than improved circulation or insulation, because these need energy.
