tiny, photosynthetic organisms
floating or weakly swimming animals that rely on water currents to move any great distance.
zooplankton that spend their entire lives as plankton.
zooplankton that spend a larval or reproductive stage as plankton.
cyanobacteria holoplankton meroplankton phytoplankton zooplankton

Explanation:

• Cyanobacteria: Blue - green algae, the earliest known life - form on earth and still the most common.
• Phytoplankton: Tiny, photosynthetic organisms.
• Zooplankton: Floating or weakly swimming animals that rely on water currents to move any great distance.
• Holoplankton: Zooplankton that spend their entire lives as plankton.
• Meroplankton: Zooplankton that spend a larval or reproductive stage as plankton.

Answer:

Blue - green algae, the earliest known life - form on earth and still the most common. → Cyanobacteria
tiny, photosynthetic organisms → Phytoplankton
Floating or weakly swimming animals that rely on water currents to move any great distance. → Zooplankton
Zooplankton that spend their entire lives as plankton. → Holoplankton
Zooplankton that spend a larval or reproductive stage as plankton. → Meroplankton
