Communities based on chemosynthesis in the ocean
By: Jose Juan Gutierrez
Chemosynthesis is the process by which organisms use chemical energy to create organic molecules. Unlike photosynthesis, which converts sunlight into energy, deep ocean organisms utilize chemosynthesis to manufacture carbohydrates and other molecules from the oxidation of sulfates.

How the study of earth science contributes to the survival of the biosphere
By: Jose Juan Gutierrez
Earth science comprises the scientific study of planet Earth. It involves the study of the sciences that deal with the formation, composition, distribution and changes occurring in the planet, including geology, oceanography, geochemistry, geophysics, meteorology, and a number of sub-disciplines. The study of Earth sciences...
