A lion eats the meat of a buffalo. How do the molecules in the buffalo act as building blocks for the lion?
The proteins that make up the buffalo are added to the proteins that make up the lion (building blocks) and used to make the fats for the body of the lion.
Meat from the buffalo is converted into energy. The lion then uses this energy to build up its body composition.
The proteins that make up the buffalo are broken into smaller parts (building blocks) that can be used to make new proteins in the body of the lion.
Meat from the buffalo is converted into energy. The lion then uses this energy to capture molecules from the air.
