What is macronutrients?
Macronutrients are the nutrients we need in larger quantities of food that provide us energy throughout the day.
What point is potential energy at when kinetic energy is at its highest point?
When kinetic energy is at its highest point potenital energy is at its lowest poing
What energy does chemical energy convert to?
Chemical energy converts to thermal energy
The digestive system is made from the GI track
What quantities of food do we need macronutrients in?
We need large quantities of food.
What is chemical energy?
Chemical energy is contained in molecules and atoms
What is an example of energy changing forms?

What does mechanical digestion NOT do?
What would happen to your immune system if you don't contain enough macronutrients?
Your immune system will constantly get weaker and weaker
What is chemical digestion?
Chemical digestion is when food travels from your mouth into your digestive system and is broken down by digestive enzymes.
Why is the law of conservation important?
The law of conservation is important because it helps us foresee the energy transformation
What would happen if there was no energy?
If there was no energy there would be no life because there is energy in everything
