Not all living things need sunlight, ie the fish and worms that live at the very depths of the ocean where light rays cannot pennetrate.

Living things need to grow and reproduce. To do this, they need to transform one form of matter into another, which requires energy. The biggest supply of energy to life on Earth comes from the Sun. Thus, most living things on Earth need sunlight, whether directly (plants) or indirectly (animals that eat plants).
Some living things do not need energy from the sun, though. All they need is heat and a special mix of chemicals that store the energy made by the heat. These can be found deep in the ocean near cracks in the earth, which let the heat out. This heat comes not from the sun, but because some rare atoms are slowly falling apart deep in the center of the earth. Life uses this energy too, where it is dark and there is no sunlight.

Not all living things need sunlight... There are living things at the bottom of the oceans which never come in contact with sunlight.

Not all living things need sunlight. Many creatures thrive very well in places where there is little or no sunlight, like the bottom of the ocean, underground, or, in caves.

so they could be strong and healthy and living things need the strength to grow. Sunlight gives living things the strength to grow.

there are many reasons that **some** living things need sunlight. ex: heat, energy, suntans. others do not. on the bottom of the ocean there are many different creatures that do not require it as one of the basic necesities of life.

A hypothesis is just a possible explanation. Your experiment may prove or disprove or may be inconclusive. Your hypothesis should be your hypothesis, not someone else's though.

Because without sunlight there would be zero energy input to this rock, and that literally is all it would be.
