they both decrease genetic variation
 
        
             
        
        
        
Reproductive isolation. Species refer to the group of organisms which share common morphological features and can interbreed and produce a viable offspring. Thus, the organisms of one species are reproductively isolated from the organisms of other species

Answer:
In general, if an organism uses energy to regulate its body temperature internally, then it is considered endothermic. If an organism instead relies on external environmental factors to regulate its body temperature, then it is considered ectothermic.
Explanation:
This is my answer.I hope it’s right.
