I believe this question is trying to get you to realize the difference between acquired traits(one you get through doing something during life) and heritable traits(ones from Mom/Dad). For example, I really wish I was 6 foot 4... but the height trait comes genetically from your parents since it is coded in my DNA how tall I will be, therefore this trait must be passed down genetically and somewhere down the evolutionary tree the humans in the region which my family comes from was better off being short. An example that comes from acquired traits could be muscularity... my parents are both not very muscular but throughout my lifetime I enjoy working out and have become much more muscular, no matter how much your parents or grandparents lift weights YOU won't change so that change must be acquired through aging during your lifetime. Now the amount of muscle your body can put on is a heritable thing but that is beside the point. Hope this helps :)
 
        
             
        
        
        
Answer:
popcorn kernels aren't living things
Explanation:
characteristics they have that show proof they are living organisms:
• movement when exposed to heat
• irritability/sensitivity since they react to change of temperature
• growth since when they are exposed to high temperatures they grow and become bigger
We can determine if they are living or not by:
• seeing if they respire
• seeing if they need nourishment 
• seeing if they can excrete
• seeing if they can reproduce
In conclusion they aren't living things
 
        
             
        
        
        
The new species come from old ancestors of the animals that were there, over time they slowly evolved, and they adapted to that new environment.

If you’re talking about too many people I’m guessing the limitation factors would be lack of resources and that would include lack of food and space.
