On cool mornings, some species of bumblebee are able to generate heat from their flight muscles. This heat warms their bodies so that they are able to fly at relatively cold temperatures and thus seek out flowers and mates earlier than most other insects. Both bumblebees and honeybees feed on nectar, which is a sugar-rich fluid produced by many flowers. Based on the above information, in the early mornings when the bumblebee heats its body via metabolic processes, it would be considered a(n) __________ and thus will have __________ oxygen demands.
