1. D. It sounds like a plant or a plant relative, and that can’t fit into A,B, or C.
2. A.
not B, since ferns don’t absorb their food
not C, since ferns don’t make ATP during photosynthesis, (they make glucose)
not D, since ferns need a source of energy (sunlight).
1. D
bacteria and archaea are single-celled
animalia don’t have chloroplasts, so that leaves eukarya
2. C
ferns are plants (photosynthesis) flatworms are animals (digestion)
hope that helps.
