What does being a Heterotroph mean?
That they get their energy from other organims
6
What does being an autotroph mean?
That they get their energy from the sun
7
What are saprotrophs?
A sub-section of heterotrophs which by the organism carries out digestion outside of the body
8
T/F Plants are saprotrophs
false, only fungi are
9
What 3 steps do saprotrophs do to digest food?
1. secrete digestive enzymes onto food outside the body
2. enzymes then break down food
