Describe how organisms can be classified in terms of their nutritional pattern. Specifically categorize organisms in terms of how they obtain organic carbon, the source of electrons for their redox reactions, and the source of energy to make ATP
Finally, use correct terminology to combine these categories to organize the types of organisms by their metabolic strategies.
What will be an ideal response?
Organisms can either "fix" inorganic carbon dioxide into organic forms by adding hydrogen (autotrophs) or must have an external source of organic carbon (heterotrophs). The initial source of electrons to power redox reactions can also be either inorganic (lithotrophs) or organic (organotrophs), Energy can be obtained from light (phototrophs) or from the chemical bonds of nutrients (chemotrophs).
Photoorganoautotroph: light / organic electron source / fixes carbon
Photoorganoheterotroph: light / organic electron source / cannot fix carbon
Photolithoautotroph: light / inorganic electron source / fixes carbon
Photolithoheterotroph: light / inorganic electron source / cannot fix carbon
Photoorganoautotroph: light/ organic electron source / fixes carbon
Chemoorganonheterotroph: nutrient breakdown / organic electron source / cannot fix carbon
Chemolithoautotroph: nutrient breakdown / inorganic electron source / fixes carbon
Chemolithoheterotroph: nutrient breakdown / inorganic electron source / cannot fix carbon
