There are three basic types of biogeochemical cycles:
-------------------------
1️⃣Gaseous type:
-------------------------
✔️In this type of biogeochemical cycles, the atmosphere constitutes the major reservoir of the element that exists there in gaseous phase.
✔️Such cycles show little or no permanent change in the distribution and abundance of the element.
✔️The Carbon, Oxygen and Nitrogen cycles are good examples of biogeochemical cycles with prominent gaseous phase.
-------------------------------
2️⃣Sedimentary type:
-------------------------------
✔️In the sedimentary type of cycle major reservoir is the lithosphere, from which the elements are released by weathering.
✔️The sedimentary types are best exemplified by Phosphorus, Sulphur, and Iodine cycles.
✔️In these cycles a little portion of the supply may get lost, as in the deep ocean sediments, and thereby becomes inaccessible to organisms and to continual cycling.
-----------------------
3️⃣Water cycle:
-----------------------
✔️The hydrologic (water) cycle has been included in gaseous types of cycles by Odum (1963).
✔️But Kormondy (1969) considers it to be a separate major cycle, involving the movement of a compound, while the others involve the movement of elements.
✔️The movement of those elements and inorganic compounds that are essential to life can be conveniently designated as the nutrient cycling.
✔️The latter may include all the three major types of cycles i.e., hydrologic cycles, gaseous nutrient cycles, and sedimentary nutrient cycles.

1) Gaseous type
2) Sedimentary type.
3)Water cycle.
These are the three types of bio-geo-chemical cycles.
Hope it helps.
