The main difference between ectotherms and endotherms is
how they obtain food to provide for their metabolism.
the source of their body heat.
whether they conserve or eliminate body heat.
whether they control their body temperature.
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.
Ectotherms: They are otherwise called wanton creatures. Fishes, creatures of land and water, reptiles are ectotherms.
Endotherms - they are otherwise called warm-blooded creatures. For example, birds and vertebrates are endotherms.
Impact of temperature on endotherms -
When the temperature is low, endotherms produce more hotness to keep the internal heat level steady. So endotherms are not influenced by the temperature of the climate.
Impact of temperature on ectotherms -
The temperature of the climate influences ectotherms. At the point when the temperature is high, ectotherms grow quicker. At the point when the temperature is low, they might foster injury.
Provide biological reasoning for your claim about endotherms.
Consider addressing the following:
-Why do you see the data you see?
-What is happening at the molecular level?
-What are the benefits and disadvantages of being an endotherm.
-How do endotherms maintain homeostasis?
