PHOSPHORUS CYCLE

ENERGY AND MATTER IN THE PHOSPHORUS CYCLE

• Matter is moved between plants
• Energy is moved between the
• Environment in this cycle

BIOGEOCHEMICAL

• The cycle in which chemical elements and
• The cycle in which chemical elements and
• simple substances are transferred between
• living systems in the environment
• living systems in the environment

THE 1ST LAW OF THERMODYNAMICS

• This law is often called the law of conservation of
• Energy. Simply stated this law states energy can
• Be changed from one form to another but energy
• Cannot be destroyed. Energy constantly changes from
• One form to another, but the total amount of energy

THE SECOND LAW OF THERMODYNAMICS

• This law states that in 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 the initial state in other words no form of energy
• Converts entirely losing some energy.

Relation of biogeochemical movements energy

• This is in line with the law of conservation of matter which states that matter cannot be created nor destroyed but can be transformed including the transformation between matter and energy

Relation of biogeochemical movements matter

• The transfer of matter involves biological, geological and chemical processes; hence the name biogeochemical cycles derives.
