Term: Autotrophic

As an autotrophic organism, Spirulina is capable of nourishing itself by deriving cell carbon from inorganic carbon dioxide and sunlight, thus producing a form of bioavailable energy.

Spirulina is therefore a producer of substances, capable of manufacturing complex organic nutritive compounds from simple inorganic sources such as carbon dioxide, water, and nitrates, using energy from the sun.

since Spirulina is NOT heterotrophic, it will not be able to utilize organic materials as a source of food.
