Answer;
-Variety
Ethan is not achieving the variety principle
Explanation;
-Eating a variety of foods and choosing the appropriate number of servings from the food guide pyramid is something that many people do not do.
-No two food items provide the exact same nutrients and this is why it is important to eat an assortment of foods. This means that some food items are better sources for nutrients than other items and vise versa.
-Balance and moderation are also important aspects of daily intake of food. Balance compares with variety because of the importance of eating a balanced diet from the Food Pyramid.

Moderation involves controlling or regulation of food intake.
It is consistent with Punctuated
equilibrium. A theory that states that when a species show up in the fossil
record they will turn into a stable record, showing almost zero evolutionary
change through their geological history. When the species do change, this
change is rapid and split the species into tow rather than make the original
species evolve into another one.
