Water
Tiny, usually microscopic, plants (phytoplankton)and animals (zooplankton) with limited powers of locomotion, usually living free in the water away from substrates. Minute plants and animals floating in bodies of water; often a major source of nutrition for larger aquatic life forms.
Climate Change
