, Organic Nutrient - CORRECT ANSWERS-An organism that contains carbon and
hydrogen
Inorganic Nutrient - CORRECT ANSWERS-An organism that does not contan carbon
and hydrogen
Phototroph - CORRECT ANSWERS-An organism that gains energy from light through
photosynthesis
Heterotroph - CORRECT ANSWERS-An organism that must obtain carbon in an
organic form - they are dependent on other life forms
Chemotroph - CORRECT ANSWERS-An organism that gains energy from chemical
compounds - this means they eat things. Harvesting energy from the things they eat.
Autotroph - CORRECT ANSWERS-An organism that gets its source of carbon from
carbon dioxide an iorganic carbon source - referred to as the "self feeder"; They are
NOT nutritionally dependent on other living things
Photoautotroph - CORRECT ANSWERS-An organism that gains its energy from light
rays and its carbon source from CO2 in the air
Examples of a photoautotroph? - CORRECT ANSWERS-Photosynthetic organisms -
algae, plants, Cyanobacteria
What kind of organism is the basis of most food webs? - CORRECT ANSWERS-
Photoautotrophs
Chemoautotroph - CORRECT ANSWERS-An organism that gets its energy from eating
things and gets its carbon source from inorganic compounds
Examples of a Chemoautotroph - CORRECT ANSWERS-Only certain bacteria/archaea
- methanogens, deep-sea vent bacteria
Lithoautotroph - CORRECT ANSWERS-gets energy from inorganic materials - can
actually digest rocks
Chemoheterotrophs - CORRECT ANSWERS-derive energy from chemical energy in the
food consumed; carbon source also comes from the food consumed
What are humans classified as? - CORRECT ANSWERS-Chemoheterotrophs
Aerobic Respiration - CORRECT ANSWERS-the principal energy-yielding pathway in
where the final electron acceptor in the electron transport chain is oxygen (O2)
Osmosis - CORRECT ANSWERS-movement of water across a permeable membrane
