What does nutrition deal with?
The study of food and its effect on the body
What is the intake of food and supplements in the body utilized with?
Maintaining health, growth, and energy
What nutrients does the body need
Carbohydrates, proteins, fats, vitamins, and minerals
What are the two kinds of nutrition?

What is autotrophic nutrition
Where a living thing makes it’s own food
What is heterotrophic nutrition?
Where a living thing must ingest its food
What is transportation?
