Answer 1

Answer:

C. ii, iii

• Heterotrophs, meaning 'other feeders', are organisms that cannot produce their own food and must obtain energy by consuming other organisms or organic matter.

• This group includes all animals, fungi, and many bacteria and protists. Their existence is entirely dependent on the energy fixed by autotrophs.

• The term 'phagotroph' specifically highlights their method of feeding by ingesting solid food particles, a characteristic common to most animals.
