Is there any form of life that relies on nuclear, rather than solar energy?

As the questions states, I am wondering if there any form of life on earth that relies on nuclear, rather than solar energy? Failing that, just any kind of life that does not require solar energy in any way?

    I would say all living things have a nuclear life as we are made of staff that has a nuclear half-life. Assuming however that the question just a straight, life it founf in places where sunlight does not reach – at the botton of the Mariana Trench there is life surviving from the vocanoe fumeroles – they are discussed here http://news.nationalgeographic.com/news/2005/02/0203_050203_deepest.html

    hope this helps.

    There is no life relying on nuclear energy.
    there is life relying on heat energy from the earths core.
    These hydrothermal vents provide both heat and a chemical cocktail that a variety of life depend on.

    Sort of. The Earth would be colder and more rigid if it weren’t for nuclear energy.

    The question is a little bit odd in that you cannot separate the energy of the sun from nuclear energy.

    The sun is basically a huge ball of nuclear reactions culminating in the production of many forms of energy including light.

    Some theories stipulate that the planets are the waste emmisions of the sun, earth for example has a molten iron core. Some believe that this iron core was expelled from the sun and became the earth.

    Even if a living organism does not receive direct light from the sun, it relies upon the energy that the sun provides to keep the planet above the temperature of the universe (approximately 3 kelvin or -270 centigrade).

    So, almost all life (I cannot say all life as the boat is still out on this one) on this planet relies upon the presence of the sun …

    The below is from my second source, you should recognise them as nuclear reactions

    1. Two protons combine to form a deuterium atom (hydrogen atom with one neutron and one proton), a positron (similar to electron, but with a positive charge) and a neutrino.
    2. A proton and a deuterium atom combine to form a helium-3 atom (two protons with one neutron) and a gamma ray.
    3. Two helium-3 atoms combine to form a helium-4 atom (two protons and two neutrons) and two protons.

    These reactions account for 85 percent of the sun’s energy. The remaining 15 percent comes from the following reactions:

    1. A helium-3 atom and a helium-4 atom combine to form a beryllium-7 (four protons and three neutrons) and a gamma ray.
    2. A beryllium-7 atom captures an electron to become lithium-7 atom (three protons and four neutrons) and a neutrino.
    3. The lithium-7 combines with a proton to form two helium-4 atoms.

    The helium-4 atoms are less massive than the two hydrogen atoms that started the process, so the difference in mass is converted to energy as described by Einstein’s theory of relativity (E=mc2). The energy is emitted in various forms of light: ultraviolet light, X-rays, visible light, infrared, microwaves and radio waves.

    The sun also emits energized particles (neutrinos, protons) that make up the solar wind. This energy strikes Earth, where it warms the planet, drives our weather and provides energy for life. We aren’t harmed by most of the radiation or solar wind because the Earth’s atmosphere protects us.
