Plankton
Tiny microscopic creatures living in the sea. Some are animals - zooplankton, some are plants - phytoplankton.
Pollutant
A harmful substance emitted into the air, water or soil.
Plankton: Tiny plants and animals that live in water.
Plate tectonics: Refers to the folding and faulting of rock and flow of molten lava involving lithospheric plates in the earth's crust and upper mantle.
Plankton: microscopic organisms floating in the water column, not associated with the substrate
Pneumatophores: vertical extensions from cable roots in black and white mangrove ...
Plankton: Tiny plants and animals that live in water.
Plasma Arc Reactors: devices that use an electric arc to thermally decompose organic and inorganic materials at ultra-high temperatures into gases and a vitrified slag residue.
Plankton: Tiny plants and animals that live in water.
Plasma-Arc Reactor: An incinerator that operates at extremely high temperatures; treats highly toxic wastes that do not burn easily.
Plankton - Plankton are forms of marine, organic life that gather vital energy for life through photosynthesis. Since they are very low on the food chain, they are vital to all marine life.
Plankton: Those organisms that are unable to maintain their position or distribution independent of the movement of water or air masses.
Pollution: The contamination of a natural ecosystem, especially with reference to the activity of humans.
plankton
Mostly microscopic (some are barely visible to the naked eye) aquatic organisms found in the lighted upper layers of the water column. Includes photosynthetic (phytoplankton) and heterotrophic (zooplankton) organisms.

Plankton are free floating minute plants or animals in the sea, lakes or rivers. The plant forms photosynthesise (above), supplying food for all the sea food chains.
plankton : 1) Small, usually microscopic, plants (phytoplankton) and animals (zooplankton) in aquatic systems. 2) All of the smaller floating, suspended or self-propelled organisms in a body of water.
Planktonic
Drifting unattached in water, the plankton include both plants and animals ranging from
microscopic to macroscopic.

Definition (english only)
Tiny, free-floating organisms of the ocean or other aquatic systems. They may be phytoplankton or zooplankton.
meroplankton Organisms with temporary planktonic phases in their life cycle, e.g., oyster and crab larvae.
phytoplankton: Phytoplankton are tiny, microscopic plants floating on the top layers of the ocean.
Phytoplankton
Free-floating, mostly microscopic aquatic plants.
Pilot tests ...
Zooplankton- Small (often microscopic) free-floating aquatic plants or animals.
phytoplankton that portion of the plankton community composed of algae and cyanobacteria
phytotrophy photosynthesis or photoautotrophy in organisms that possess chlorophyll a and that use water as an electron donor in reducing carbon ...
Red Tide A sudden surge in toxic, naturally occurring microscopic red plankton in coastal waters, often causing dead fish to wash up on beaches.
The "El Niño" current may prevent the upwelling of nutrient-rich cold waters, resulting in the death of large quantities of plankton and consequently in a reduction in surface fish populations which depend upon the plankton for food.
Red Tide: A proliferation of a marine plankton toxic and often fatal to fish, perhaps stimulated by the addition of nutrients. A tide can be red, green, or brown, depending on the coloration of the plankton.
Most species of algae or phytoplankton are beneficial, not harmful. They are essential elements in the foundation of the global food chain. Without them, higher life forms, including humans, would not exist and could not survive.
The total weight of a group or stock of living organisms (e.g. fish, plankton) or of some defined fraction of it (e.g. spawners) in an area, at a particular time.

A Swedish word, pronounced ""yut-tya."" A nutrient-rich sedimentary peat consisting mainly of plankton, other plant and animal residues, and mud. It is deposited in water in a finely divided condition.
Proposals include mirrors in space to reflect sunlight and stop it entering the atmosphere, dumping sulphur dioxide into the atmosphere to reflect sunlight, putting iron in the oceans to stimulate the growth of phytoplankton, ...
When this happens, the typical pattern of coastal upwelling that carries nutrients from the cold depths to the ocean surface is disrupted, and fish and plankton die off in large numbers.
Flagellated, photosynthetic, marine protists. They are very small in size and are components of plankton, a major food source at the bottom of the marine food chain.
Dinoseb ...
Note: Such a system would commonly have a terrestrial phase, with substrate, plants and herbivores, and an aquatic phase, with vertebrates, invertebrates and plankton.
Aluminium causes some fish to produce an excess of mucus around their gills, preventing proper ventilation. Phytoplankton growth is inhibited by high acid levels, and animals which feed on it suffer.
"8 "OCs deposit to a greater degree in colder regions, accounting for their unexpectedly high concentrations observed in the air, sea water, plankton, wildlife, and people in the Arctic region."9 ...
Eutrophication Enrichment of a water body with plant nutrients; usually resulting in a community dominated by phytoplankton. Evapotranspiration The water loss to the atmosphere from soil and vegetation.
