The elements move through abiotic and biotic factors, in these cycles, and a state of equilibrium is maintained n the ecosystem. The carbon dioxide levels are responsible fr the temperature of the earth. If Carbon cycles would not have existed, then there would have been a disruption in maintaining the global temperature. Biogeochemical cycles basically continuously recycles the essential materials, for sustaining the life-forms.</span>
Proteins
Enzymes are proteins that can lower activation energy of reactions in the body (I think).
<span>Solar and wind is the list that contains the only examples of renewable sources of energy. Solar energy is generated by using sunlight while wind energy is generated by using wind turbines. Hence both of these energies does not require any form of burning of fuels and hence are renewable sources of energy.</span>
