1. Compare gaseous biogeochemical cycle and sedimentary biogeochemical cycle.​

Gaseous cycles include those of nitrogen, oxygen, carbon, and water; sedimentary cycles include those of iron, calcium, phosphorus, and other more earthbound elements. In a sedimentary cycle elements move from land to water to sediment. Main reservoirs are the soil and sedimentary rocks.

C I think. Because multiple cells would have different functions. Sorry if im wrong. btw.
