Biogeochemical cycle; Introduction and description
What is a biogeochemical cycle?
The cycling of chemical elements required
by life between living and non-living part
of environment is called biogeochemical
The examples of elements are;
All these elements are macro-elements.
Other chemical elements in the cycle which are
formed as intermediates can be microelements.
These elements are cycled through;
The duration of cycle depends upon;
Chemical reactivity of the substance
Chemical state of substance
Important biogeochemical cycles are;
We need biogeochemical cycles
Storage of key elements
Transport of key elements
To make the key elements available for
To balance the ecosystem
Recycle the energy
Causes of disturbance of
Burning of coal
Wastage of non-renewable sources
Depletion of natural sources
The need of the hour is that we
must try to reduce the harmful
activities to protect the LIFE..
