Student A claims the order should be B, E, D, A, C. Their reasoning is that since the small circles without lines in the index cards represent chloroplasts, photosynthesizing organisms evolved before aerobic organisms.

Student B claims the order should be B, A, C, E, D. Their reasoning is that since the small ovals with lines in the index cards represent mitochondria, respiratory organisms evolved before photosynthesizing organisms
