The two correct statements that describe cyanobacteria are:
1. **Cyanobacteria were the first photosynthesizing organisms.**
2. **Cyanobacteria lived in the ocean.**
Cyanobacteria are unicellular organisms and do not have a nucleus, so the statement regarding complex cells with a nucleus is incorrect. Additionally, cyanobacteria are known to have increased, not decreased, oxygen levels in the atmosphere during the Great Oxygenation Event.
