on Earth’s surface derives its energy from the Sun. Another
realm of life thrives around seafloor hot springs and in fluid-
filled cracks deep below the surface, utilizing the chemical
energy of those environments. The chemistry that builds and
sustains life requires a fluid medium in which atoms and
molecules can react. For all known forms of life, liquid water
provides that environment. Carbon atoms are ideally suited to
form complex molecules. Carbon is the structural backbone of all
the building blocks and material for life, including proteins
and DNA.        Show more   • For Educators      • Topic:
