Final answer:
Organisms are classified based on their cells being unicellular, prokaryotic, or autotrophic. Unicellular organisms can be either prokaryotes or eukaryotes. Autotrophic organisms produce their own food using inorganic materials.
Step-by-step explanation:
Organisms are classified as unicellular, prokaryotic, or autotrophic based on certain criteria or aspects.
Unicellular organisms are made up of a single cell. They can be either prokaryotic or eukaryotic. Prokaryotic cells lack a membrane-bound nucleus and organelles, while eukaryotic cells have a membrane-bound nucleus and organelles.
Autotrophic organisms are able to produce their own food using inorganic materials. They can utilize carbon dioxide as their main source of carbon and capture energy from the sun through photosynthesis.
