Energy flow is required to maintain the structure of organisms by the formation and splitting of phosphate bonds.
If photosynthesis is reduced, atmospheric concentrations of carbon dioxide can build up and stimulate global warming atmosphere which may contribute to increased melting of glaciers hydrosphere. The hydrosphere contains all of the solid, liquid and gaseous water on Earth, extending from the depths of the sea to the upper reaches of the troposphere where water is found.
David M. The elements carbon , hydrogen, nitrogen, oxygen, phosphorus, and sulfur, when combined as proteins, lipids, carbohydrates, and nucleic acids, provide the building blocks, the fuel, and the direction for the creation of life. The major consideration in the community is the living component, the organisms; the abiotic factors of the environment are excluded. Ecosystems may be further subdivided into smaller biotic units called communities.
Although environmental and earth science cover essentially the same material, environmental science places greater emphasis on the biological realm, while earth science places greater emphasis on the physical realm.
Some of these populations eventually become so genetically different that their members cannot successfully interbreed, resulting in the evolution of a separate species speciation.

The genetic variation that is necessary for a species to adapt to the physical environment and to other organisms arises from new mutations within populations, the recombination of genes during sexual reproduction, and the migration of and interbreeding with individuals from other populations.
