It depends. Most of the autotrophs you have seen are green plants and they ultimately get their energy from the sun through photosynthesis. In the oceans, around volcanic vents, entire ecosystems get their energy from organisms that absorb the dissolved chemicals for energy. These are chemoautotrophs or 'chemotrophs' for short.
Autotrophs are organisms that produce their own organic compounds using carbon dioxide from the air or water in which they live. To do this they require an external source of energy.
The ultimate source of energy that autotrophs use to produce their own food is the sun. They use the sun with carbon dioxide and make a chemical reaction called photosynthesis.
Sunlight and/or chemical energy
the sun
The sun is the ultimate source of energy for the vast majority of organisms. Producers convert the energy from sunlight into chemical energy stored in glucose molecules. Glucose molecules are combined to make starch for energy storage. Primary consumers (heterotrophs) feed on producers (autotrophs), and secondary consumers feed on primary consumers, and so on.
Autotrophs are organisms that make their own food, such as plants. their food comes form the sun meaning they use light energy to produce food. Although heterotrophs ultimately get their energy from the sun, but the way they obtain is different. in heterotrophs they obtain energy from the food they consume. For example eating plants that have obtained energy from the sun, or by eating animals that have eaten such plants.
producers or autotrophs and consumers or hetrotrophs
most plants use the same amount of oxygen they produce. if animals use oxygen but do not produce, why haven't we run out of oxygen
An autotroph uses co2 as primary carbon source where as chemotroph uses chemicals as primary energy source. Chemotrophs also require a source of organic nutrient, and autotrophs would be considered a photosynthesizer.
Heterotrophs depend on the sun for energy because they eat other hetertophs and autotrophs. As you know autotrophs eat plants sp when a heterotroph eats one, it gets the energy. Or it receives it directly by eating the plants/autotrphs. I hope this answered your question. -Skylar =P OR~ The ultimate source is where the energy came from originally. Heterotrophs get their energy from autotrophs, which get their energy from the sun. So, that means the original (or ultimate) source of energy is the sun.

plants are not the ultimate source of energy. It is the sun which is the ultimate source of energy to this planet
Photoautotrophs use light as the energy source for producing proteins, lipids and other organic substances. Examples of photoautotrophs are plants.
The sun is the ultimate source of energy for the vast majority of organisms. Producers convert the energy from sunlight into chemical energy stored in glucose molecules. Glucose molecules are combined to make starch for energy storage. Primary consumers (heterotrophs) feed on producers (autotrophs), and secondary consumers feed on primary consumers, and so on.
It is essencial to photosynthesis, they way that autotrophs (basically) get their energy. Autotrophs are at the bottom of the food chain, so indirectly supply energy to everything else. In fact it may not be the sole source. Various species of life has been found in the ocean depths miles below the limit of sunlight penetration, fed by geothermal (volcanic) energy from fumeroles and 'stacks'.
Energy is essential to life, and radiant energy from the sun is the ultimate source of energy for nearly all organisms in any ecosystem.Organisms called producers (autotrophs) capture energy from the sun. They use this energy and various nutrients from soil or water to synthesize (produce) the substances they need to grow and to support their other activities all by themselves.

The ultimate source of energy for plants is the sunlight which theycapture it from the sun. It is one of the main components ofphotosynthesis.
