You don't give the list, but this would be meiosis.
The cell is fully mature and has all its DNA and organelles duplicated and is ready to begin mitosis after interphase.
Autotrophs are the producers, i.e. plants (they make their own food) so they gain their energy by converting light energy into chemical energy through the process of photosynthesis. Whereas heterotrophs (animals) cannot make their own food so they obtain nutrition through the consumption of autotrophs and other heterotrophs.
