Conservation of Energy

Conservation of Mass
Matter can be changed from one form into another, mixtures can be separated or made, and pure substances can be decomposed, but the total amount of mass remains constant.
The total energy of an isolated system cannot change. Energy can not be created or destroyed only changed in form.
The net primary productivity of producers like plants and plankton is the amount of light converted into chemical compounds minus energy lost through respiration.
