heterotrophy?

Answer 1

need to take in organic compounds to live since they cant make their own food

Answer 2

A heterotroph (Greek heterone = (an)other and trophe = nutrition) is an organism that requires organic substrates to get its carbon for growth and development.

Heterotrophs are unable to synthesize organic, carbon based compounds independently from the inorganic environment's sources.

For a species to be termed a heterotroph, it must obtain its carbon from organic compounds. If it obtains nitrogen from organic compounds, but not carbon, it will be deemed an autotroph. If a species obtains carbon from organic compounds then there are two possible subtypes of these heterotrophs:

photoheterotroph — obtains energy from light
chemoheterotroph — obtains energy from the oxidation of inorganic compounds
In simpler terminology, a heterotroph is an organism that is incapable of making its own food from light or inorganic compounds, and feeds on organisms or the remains of other organisms to get its necessary energy to survive.
