Q1 Organic Nutrient
A An organism that contains carbon and hydrogen
Q2 Inorganic Nutrient
A An organism that does not contan carbon and hydrogen
Q3 Phototroph
A An organism that gains energy from light through photosynthesis
Q4 Heterotroph
A An organism that must obtain carbon in an organic form - they are dependent on other life
forms
Q5 Chemotroph
A An organism that gains energy from chemical compounds - this means they eat things.
Harvesting energy from the things they eat.
Q6 Autotroph
A 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
Q7 Photoautotroph
