Plant photosynthesis is the primary source of nutrients in every ecosystem. Deep in the ocean, where little or no sunlight is present, photosynthesis is impossible. Thus, organisms in deep water ecosystems depend on detritus (discarded waste) and other organic matter that drifts down from (and is generated) nearer to the surface, or on species that migrate back and forth.

Living organisms have the ability to store energy in many different forms. To store solar energy, living organisms create carbohydrates for their storage needs.
Living organism depend on plants because of the plants capability to do photosynthesis. Photosynthesis is converting the sun energy into a glucose type sugar. Sugar is a type of energy that all living organisms need.
Fats and oils are energy stores in organisms

All living organisms, that are catagorized as consumers, depend on eating other organisms for energy, although, producers create their own energy from the abiotic features of an ecosystem.

Living organisms depend on one another and on their environment for survival.
All living organisms depend on diffusion.Organisms that rely on diffusion alone are almost always single celled organisms.
Living organisms depend on other living organisms as food sources. AN overpopulation of a certain living organism or a decrease in a population of an organisms may unstable the other organisms that depend on it for food.
the ultimate source of energy for all living organisms is the sun
Living organisms use food for energy. Without energy, no living organism can do anything.
