The main source of energy for all living things is what they eat. In other words every source of energy comes from the sun. Some clarification: if a bird eats a snake and the snake ate a rabbit and the rabbit ate a carrot and the carrot got sunlight the owl got energy from the sun.
Water and Light
All Organism need Food to promote growth and for energy.
Food provides nutrients and energy we need.
organelles need many things to survive but they mostly need energy, water, mineral's, and vitamins
Yes they do, true
Enzymes allow many chemical reactions to occur. They catalyze reactions by lowering the activation energy, which is the amount of energy needed to trigger a chemical reaction. Whereas heat can provide energy to trigger reactions, temperatures needed to reach activation energy for most metabolic reactions are often too high to allow cells to survive, so enzymes are in fact needed if metabolism (anabolic or catabolic) is to occur.

Leukocytes are part of the body, not separate organisms. As such they obtain their energy by metabolizing the sugars in the blood stream to produce needed energy. Strictly speaking, they do not "feed on" anything. They absorb and process sugars.

They conduct aerobic respiration. They provide energy needed
Organisms need to carry out the process of respiration because the cells in the organisms break down simple food molecules and release their energy.
the structures or behaviors survive many essential things.
