All organisms need to break down food in order to use it, no matter if it´s a producer or a consumer.
Nutrients are made up of molecules, which is a substance made when 2 or more atoms combine.
Examples: a) H2O b) CO2
Biological Molecules like:
Proteins
Carbohydrates,
Lipids,
ATP
Nucleic Acids.

Proteins
Proteins are made up of small units called AMINO ACIDS.
Amino acids link together forming long chains.
So when we eat, we break down food proteins to get amino acids to produce new proteins in our bodies.
Enzymes help to start or speed up chemical reactions in cells.

ATP is the major energy-carrying molecule in the
cell.
The energy stored in carbohydrates and lipids must be transferred to ATP, which then provides fuel to cellular activities
