What are examples of an autotroph and a heterotroph?

Answer 1

AUTO
pretty much any plant that uses photosynthesis,
algae, trees.
an autotroph is an organism that makes it's own food
as opposed to a heterotroph that consumes to create energy (ATP, etc)

HETERO
E. coli is a common bacterium that is a heterotroph.A heterotroph is any organism that doesn't produce its own food (but gets it through eating other things and such), and is the opposite of an autotroph, which makes its own food. Some heterotrophs would be birds, lions, elephants, bears, humans, ect., just whatever can't produce its own food like plants can.

Answer 2

An example of an autotroph is a plant, which produces its own food through photosynthesis. An example of a heterotroph is a human, which obtains its food by consuming other organisms.
