    Biogeochemical cycles mainly refer to the movement of nutrients and other elements between biotic and abiotic factors.” The term biogeochemical is derived from “bio” meaning biosphere, “geo” meaning the geological components and “chemical” meaning the elements that move through a cycle. The matter on Earth is conserved and present in the form of atoms. Since matter can neither be created nor destroyed, it is recycled in the earth’s system in various forms. The earth obtains energy from the sun which is radiated back as heat, rest all other elements are present in a closed system. The major elements include: Carbon Hydrogen Nitrogen Oxygen Phosphorus Sulphur These elements are recycled through the biotic and abiotic components of the ecosystem. The atmosphere, hydrosphere and lithosphere are the abiotic components of the ecosystem. Types of Biogeochemical Cycles Biogeochemical cycles are basically divided into two types: Gaseous cycles – Includes Carbon, Oxygen, Nitrogen, and the Water cycle. Sedimentary cycles – Includes Sulphur, Phosphorus, Rock cycle, etc.

    Plasma membrane is also called cell membrane(everyone knows this ?) 1)Cell membrane is present in both plant and animal cell but cell wall is present only in plant cell. 2)cell membrane is to give a shape and protection to the cell and cell wall in plant cell is to give extra protection to the plants (Extra point: Cell walls are present only in plant cell because animals have bones to protect them but plants don't have bones so they have cell walls for each cell to protect the cell from hypotenic solution {osmosis} from bursting .
