Do all livingthing needs light

Answer 1

Directly, no. Indirectly, yes.

think about bats, they fly at night and sleep in dark caves during the day, no sun. But indirectly they still "sort of" require energy from the sun because they eat bugs and bugs eat leaves, which do require the sun.

There are deep sea creatures that don't even have eyes because they live so far down they never get sunlight at all. But they eat things that do require light, like plankton, and other fishes that can see.

earthworms do not require sunlight, but they eat dirt which is composed of decomposed leaves....
