How could the increasing global temperature associated with climate change impact ectotherms?
ectotherm diversity will decrease in cool regions.
ectotherms will be able to be active all day in the tropics.
ectotherms will have to expend more energy to cool their body temperatures.
ectotherms will be able to expand into new habitats.

The best answer to this question, given the research found from a study done by the University of Queensland, on 2014, and which expanded along 40 years of collected data on ectotherms, would be: Ectotherms will have to expend more energy to cool their body temperatures.

Explanation:

Ectotherms is the term used to describe animals whose regulation of body temperature depends mostly on the external environment and the conditions of it. This group represents around 90% of animals and their development and wellbeing depends on the climate, especially temperature, conditions, on an environment. One positive side to ectotherms is that they have an easy adaptation rate to changing climate. However, according to the study carried out by the University of Queensland, ans which was published in 2014, ectotherms are finding it a challenge to cope with the rate of change in climate temperatures duw to global warming. This rise in temperatures is leading animals to have to expend much more energy with the rise of temperatures and thus, there has been a drop in animal reproduction and generation of new species.

Ectotherms will have to expend more energy to cool their body temperatures.
