The organisms that produce oxygen in the ocean are:
1) **Cyanobacteria** - These are photosynthetic bacteria that can produce oxygen.
3) **Phytoplankton** - They are microscopic plants that perform photosynthesis and are a major source of oxygen in oceanic waters.
4) **Algae** - Many types of algae, especially marine algae, also produce oxygen through photosynthesis.
**Zooplankton** (2) do not produce oxygen; they are primarily consumers and feed on phytoplankton and other small organisms.
In summary, the correct answers are 1) Cyanobacteria, 3) Phytoplankton, and 4) Algae.
