Explanation:

1. For question 5: EAR is defined as the average daily nutrient intake level that meets the needs of half the healthy individuals in a specific life stage and gender group. AI is an intake set when EAR can't be determined, RDA meets needs of 97-98% of the group, and DRI is the overall set of these reference values.
2. For question 6: Minerals are inorganic elements that support bodily maintenance and function. Vitamins are organic, while proteins and fats are organic macronutrients.
3. For question 7: Non-essential nutrients are those the body can produce in sufficient quantities for its needs, unlike essential nutrients which must be obtained from the diet.
4. For question 8: Essential nutrients are compounds the body cannot make on its own (or not in enough amounts) and are required for proper growth and development, so they must be consumed through diet.

Answer:

1. EAR (Estimated Average Requirement)
2. Mineral
3. Non-Essential Nutrient
4. Essential Nutrient
