introduction to nutrition in living organisms
Habitat: the natural home or environment of an animal, plant, or other organism.
Autotrophic (origin): an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide. From the Greek words auto, meaning “self,” and troph, meaning “feeding.”
Photosynthesis (origin): This is a compound word made up of photo (which means “light”) and synthesis (which means “to put together”).
Heterotrophic (origin): an organism deriving its nutritional requirements from complex organic substances (cannot synthesis it’s food by itself). From Greek heteros “other” and troph, meaning “feeding”.
Holozoic nutrition: is a type of heterotrophic nutrition that is characterized by the internalization (ingestion) and internal processing of gaseous, liquids or solid food particles. From Greek: holo-whole ; zoikos-of animals
Parasites: an organism that lives in or on an organism of another species (its host) and benefits by deriving nutrients at the other’s expense.
Saprophyte: a plant, fungus, or microorganism that lives on dead or decaying organic matte
