BIOGEOCHEMICAL CYCLES
The Oxygen Cycle
COMBUSTION
the process which generates fire also requires oxygen, along with heat and fuel. This process also uses up oxygen and releases carbon dioxide into the atmosphere.
RESPIRATION
The oxygen that is released by plants is used by humans, animals, and other organisms for respiration.
-
PHOTOSYNTHESIS
Oxygen is released into the air as a product of photosynthesis, the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy.
The Nitrogen Cycle
-
NITROGEN FIXATION
It is a process by which atmospheric nitrogen is converted into the form which can be easily absorbed the organisms on earth.
-
-
The Carbon Cycle
COMBUSTION
The process where fuels are burnt to provide energy for various activities adds to the CO2 in the atmosphere.
PHOTOSYNTHESIS
During photosynthesis, plants absorb carbon dioxide to make simple sugars.
RESPIRATION
In respiration, oxygen may be used to convert glucose into carbon dioxide. then it goes back in the atmosphere.
The Water Cycle
-
CONDENSATION
The transition process from the vapour state to the liquid state is called condensation. By condensation, water vapour in the atmosphere is released to form precipitation.
EVAPORATION
The transfer of water from the surface of the Earth to the atmosphere. By evaporation, water in the liquid state is transferred to the gaseous state.
