Trophs

Question 1

Autotrophs

Answer 1

An organism that produces its own food. Take in inorganic compounds and expel organic compounds

Question 2

Heterotroph

Answer 2

An organism that obtains its energy and nutrients from external living organisms.
Take in organic compounds and expel inorganic compounds.

Question 3

Organic compounds

Answer 3

Compounds that are not found on the periodic table. Autotrophs expel these, heterotrophs take these in

Question 4

Inorganic compounds

Answer 4

Compounds found in the periodic table. Autotrophs take these in, heterotrophs expel these.

Question 5

Photoheterotroph

Answer 5

An organism that obtains it’s energy from sunlight and carbon from organic compounds ( Not carbon dioxide)

Question 6

Photoautotroph

Answer 6

Organisms that carry out photosynthesis using energy from sunlight, carbon dioxide and water producing organic compounds.

Question 7

Chemoautotrophs

Answer 7

An organism that uses the oxidation of inorganic molecules (e.g. Sulfur, magnesium) as it’s energy source and carbon dioxide to synthesize organic compounds

Question 8

Chemoheterotrophs

Answer 8

Organisms that are unable to produce their own organic compounds. These organisms must ingest carbon molecules (e.g. sulfur, carbohydrates, lipids and proteins) synthesized by other organisms. They use inorganic molecules (e.g. Sulfur, magnesium) as their energy source.
