Step-by-step explanation:
The first cells were probably heterotrophs. They probably got their energy from other molecules in the primitive seas, and remember that the Earth's atmosphere was poor in oxygen, as were the primitive seas.
Now, the oxygen-rich atmosphere was achieved thanks to the development of unicellular photosynthetic organisms. The first cells capable of oxygenic photosynthesis were cyanobacteria that appeared about 3.45 billion years ago. Finally, applying the endosymbiotic theory, more specialized cells with organelles such as eukaryotes appeared, and later, from these unicellular eukaryotic cells, they evolved towards tissue specialization, giving rise to multicellular organisms.
We can conclude that the correct answer is:
Answer: the order of how life appeared on Earth is:
1) Anaerobic Heterotroph Phokaryote
2) Photosynthetic Autoteophic Prokaryote
3) Eukaryote cell
4) Multicellular Eukaryote
