To prevent erosion on the coastline while protecting coral reefs, the correct two answers are:
- **By promoting coral growth and planting plans.**
- **By leaving coral reefs undisturbed.**
As for the evidence that oxygen levels in the sea increased due to photosynthetic bacteria, one key piece of evidence comes from geological studies of ancient rocks. These studies show a significant increase in the levels of oxygen in the atmosphere and oceans during the Great Oxygenation Event, which is believed to have been largely caused by the photosynthetic activity of cyanobacteria. Additional evidence includes the presence of banded iron formations in sedimentary records, which indicate that oxygen was being produced and accumulated in the oceans.
