APES aquatic biomes

Phytoplankton live near the surface of the water because

• they eat krill which only are abundant near the surface of the water
• there are less predators near the surface of the ocean
• sunlight cannot reach great depths and they need it for photosynthesis
• they are blown there from the land and end up floating on the surface of the water until they are consumed
