What is the difference between endothermic and ectothermic? Give an example of each.
Endothermic: warm blooded organism that body temperature stays the same no matter what happens with the temperature of environment. Ex:mammal.
Ectothermic: cold blooded organism the body temperature changes with its environments temperature. Ex: Reptile
What is a classification system? Give an example of a classification system. It can be one you have seen before or you can create your own.
A classification system is a method of sorting and grouping objects and organisms. Classification systems are used to help scientists think about living things. It is largely based on structural features. Ex: Sorting our paper clips. We sorted by size and color.
