Yes, they all do. Plants have to have sunlight to survive and animals must have plants to survive. If we were hit by a rather larger comet, a large amount of dust would block sunlight for up to two years. All plants would begin to die and most would be gone in six months. Animals would all be gone in a year.
An organism that uses sunlight to make food or energy is known as a producer. An example of a producer is a plant. The plant utilizes the sunlight as energy to produce food.
Most ecosystems ultimately rely on sunlight as the source of energy. Sunlight is used by plants to manufacture food. Plants are eaten by herbivores, and herbivores are in turn eaten by top-level consumers like hawks. Therefore hawks ultimately depend on sunlight for their food. At the bottom of the sea, near thermal vents, scientists have discovered new ecosystems that do not rely on sunlight, but on the chemicals and heat present at those vents as a source of energy for bacteria, which are eaten by larger organisms. The top level consumers in those ecosystems do not depend on sunlight for their food.
they depend for food
Yes, organisms that perform photosynthesis, such as plants, algae, and some bacteria, depend on sunlight for energy. Through the process of photosynthesis, these organisms convert sunlight into chemical energy that they can use for growth and survival.
-- All depend on heat. -- Most depend on light. -- Those in specialized occupations, such as microwave engineers, radio announcers, and tanning salon proprietors, depend on other bands of EM.
The kind of nutrition in which an organism prepares its own food and does not depend on other organisms. Such type of nutrition is found in green plants having Chlorophyll, To manufacture their own food in the presence of sunlight. Just contrating to this are Heterotrophs (Heterotrophic nutrition), which depend on green plants or other organisms for food. Autotrophic nutrition provides food for the whole of the living world.

Organisms that make their own food with sunlight or chemical energy are called autotrophs.
Organisms that use sunlight are photosynthetic (like plants, algae, etc.) and organisms that must eat food are consumers (us, etc.).
Organisms depend on each other for food and shelter. For example, herbivores depend on plants for food, while plants depend on herbivores for pollination. Organisms also depend on each other for protection, such as cleaner fish removing parasites from larger fish in a mutualistic relationship.
In order to see if all organisms get their food from sunlight, we must first see what an organism is. An organism is a living thing that dies if it is not nourished. The only organisms that get food from sunlight are plants. Fungi and animals gain nourishment from extensive root like systems and ingestion, respectively.
