Solution

Nitrogen cycle is an example of gaseous cycle where the material involved in circulation between biotic and abiotic components of biosphere are gases. The reservoir pool is atmosphere. On the other hand, in sedimentary cycle, the reservoir pool is lithosphere and the circulating material is non-gaseous, e.g. phosphorus, sulphur, etc. The pyramid of biomass in aquatic environment, e.g. sea is inverted.
