iron, carbon, sodium, which they get from the planet. They can get energy from the light of the star or geothermal energy from the heat of the planet-Life doesnt need to be supported.It flows freely throughout the universe.......
How do they support life? Please help me):

-
what does life need to exist...


liquid water - there needs to be H2O and enough energy from the star to keep the water in liquid form

an environment to live and grow - organisms need nutrients such as potassium, iron, carbon, sodium, which they get from the planet. They can get energy from the light of the star or geothermal energy from the heat of the planet

Life doesn't need to be supported. It flows freely throughout the universe. It only gets trapped in very rare circumstances, such as on Earth.
