Some organisms are able to survive without sunlight and photosynthesis through similar processes, for example cellular respiration. Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water.
some organisms depend on other things. like worms survive in soil. plants in fact NEED photosynthesis to make their food. Bats depend on other sources of food so they don't make their own food. they also don't need sunlight cause that is when they go search for food.
