Even if some micro-organisms can be preserved in the dry state (e.g., after freeze-drying), their growth is not possible without water. [citation needed] Micro-organisms also require sufficient space to develop.
Water intensity varies in the energy sector, with oil and gas production requiring much less water than oil from tar sands or biofuels. Choosing biofuels for energy production should require a careful balancing of priorities, since water that has been used to grow feedstock for biofuels could also have been used to grow food.
The inert components of an ecosystem are the physical and chemical factors necessary for life—energy (sunlight or chemical energy), water, heat, atmosphere, gravity, nutrients, and ultraviolet solar radiation protection.
