<em><u>Biogeochemical cycles are cycles or pathways through which a chemical element or a molecule circulates through the abiotic (non-living) ad biotic (living) components of an ecosystem.</u></em>
<u><em>All chemical elements occurring in organisms are part of biogeochemical cycles.</em></u> Carbon, hydrogen, oxygen and nitrogen are the key components in life of organisms. Therefore, the carbon, nitrogen, and oxygen cycles are the most important biogeochemical cycles.
<em><u>Biogeochemical cycles are essential for life and important to the ecosystems because matter on earth is limited in amount, and space for dead organisms as well. </u></em>
<em><u>Additionally, biogeochemical cycles are important as as they transport and store these chemical elements so that they can be used by living organisms. </u></em>
The granum is a part of the chloroplast. The chloroplast contains the chlorophyll pigment and it is necessary for the trapping of the energy present in the sunlight. As a result of this the photolysis of water takes place and hence water is broken down from water molecule to proton and oxygen
The population history of the island remains highly controversial. In addition to internal conflict, the population crash has been attributed to “ecocide,” in which the Island's resources were exhausted by its inhabitants, reducing its ability to support human life.
