True or false glucose is the primary nutrient for all living things

True

Why? The primary source of energy for animals is carbohydrates, primarily glucose: the body's fuel. The digestible carbohydrates in an animal's diet are converted to glucose molecules and into energy through a series of catabolic chemical reactions.

Hope this helps :D

What is the question? if you were looking to design a method of separating something, you can separate this compound by putting both in water and allowing the water to dissolve the sugar. then pour it into another beaker and evaporate it then boom! salt and sugar : ) 

It's either -limiting factors or -scarce resources but i'd go with my first answer since the food and water are abundant they really aren't scarce
