explain the difference between ectotherms and endotherms, and give examples of each?
What is the trade-off of ectotherms with regard to maintaining an internal environment that doesn’t vary much?
Ectotherms are larger than endotherms because they need to have a larger surface area to volume ratio in order to either increase or lower their temperature.
Ectotherms usually have fur in order to conserve heat when they live in very cold environments.
Ectotherms are smaller than endotherms because they need more surface area to dissipate heat relative to their insides.
Ectotherms can survive in a wider variety of habitats because they are smaller and can behaviorally adapt to a wide variety of temperatures.
Distinguish between the following Ectotherms and Endotherms.
