Suggest, with a reason, how the activity of the sloth varies with ambient temperature.

[1]

Markscheme
  1. the sloth will be more active at higher temperatures as it takes in more food for energy;
  2. as temperature rises, the sloth uncurls to dissipate/lose heat;

Reason required.

Examiners report

Good reasoning was not seen often, best answers needed some of the elements in this linkage: higher temperature led to uncurling which led to movement which led to eating because of energy needs; "sloth prefers staying curled up so cold does not affect them" or "sloth enjoys staying curled up" were not acceptable
