To carry out photosynthesis.Every and each animal depend on this energy
Light is essential for photosynthesis, the process by which plants and some other organisms convert light energy into chemical energy to make food. Without a constant supply of light, photosynthesis cannot occur and the organism will not be able to produce the energy it needs to survive.
An organism needs energy and constant supply of materials to grow and develop.

light energy
The organism will surely die if it does not obtain energy since it needs energy to carry out everyday functions.
Light
from water
Three resources every organism needs from its habitat are nutrients, water, and somthing to breathe.
If an organism changes sunlight and carbon dioxide into the oxygen and sugars it needs to make energy, it is a photosynthetic organism, typically a plant or algae. This process is known as photosynthesis, where chlorophyll in the organism captures sunlight to convert carbon dioxide and water into glucose and oxygen. This ability to produce its own energy distinguishes photosynthetic organisms from heterotrophs, which rely on consuming other organisms for energy.
It might get enough energy for its needs, or it might not.Note that this is the usual situation - there are usually other organisms, with which an organism has to compete.
Around 90% of the energy that enters an organism is typically used for metabolic processes like growth, maintenance of body functions, and reproduction. This energy is converted into various molecules that the organism needs for its physiological processes.
