8. Ocean LifeOcean Life
Life began in the ocean, and the ocean remains home to the
majority of Earth's plants and animals—from tiny unicellular
organisms to the blue whale, the planet's largest living animal.
Most of the ocean's plant life consists of microscopic algae called
phytoplankton that float at the surface and through photosynthesis
produce about half of the oxygen that humans and all other
terrestrial creatures breathe.
