BIOS 242 ACTUAL TEST PAPER UPDATED
COMPLETE QUESTIONS WITH VERIFIED
ANSWERS
●● Inorganic Nutrient
Answer: An organism that does not contan carbon and hydrogen
●● Phototroph
Answer: An organism that gains energy from light through
photosynthesis
●● Heterotroph
Answer: An organism that must obtain carbon in an organic form - they
are dependent on other life forms
●● Chemotroph
Answer: An organism that gains energy from chemical compounds - this
means they eat things. Harvesting energy from the things they eat.
●● Autotroph
Answer: 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
Answer: An organism that gains its energy from light rays and its carbon
source from CO2 in the air
●● Examples of a photoautotroph?
Answer: Photosynthetic organisms - algae, plants, Cyanobacteria
●● What kind of organism is the basis of most food webs?
Answer: Photoautotrophs
●● Chemoautotroph
Answer: An organism that gets its energy from eating things and gets its
carbon source from inorganic compounds
●● Examples of a Chemoautotroph
Answer: Only certain bacteria/archaea - methanogens, deep-sea vent
bacteria
●● Lithoautotroph
Answer: gets energy from inorganic materials - can actually digest rocks
●● Chemoheterotrophs
, Answer: derive energy from chemical energy in the food consumed;
carbon source also comes from the food consumed
●● What are humans classified as?
Answer: Chemoheterotrophs
●● Aerobic Respiration
Answer: the principal energy-yielding pathway in where the final
electron acceptor in the electron transport chain is oxygen (O2)
●● Osmosis
Answer: movement of water across a permeable membrane
●● Simple Diffusion
Answer: The movement of molecules from a higher concontration to a
lower concentration
●● Facilitated Diffusion
Answer: a molecule binds to a specific carrier protein that changes the
shape of the cell and carries the molecule across the membrane
●● Active Transport
