HOW MATTER MOVES IN THE PHOSPHORUS CYCLE

1ST LAW OF THERMODYNAMICS

• This law is often called the Law of Conservation of Energy.
• This law states that energy can be changed from one form to another, but it cannot be created nor destroyed.
• Energy constantly changes from one form to another, but the total amount of energy available in the universe is constant.

2ND LAW OF THERMODYNAMICS

• This law states that all energy exchanges if no energy enters or leaves the system.
• The potential energy of the new state will always be less than that of the initial.

BIOGEOCHEMICAL CYCLE

• Relating to or denoting the cycle in which chemical elements and simple substances are transferred between living systems and environments.
