AQUATIC BIOMES
Aquatic BiomeThe aquatic biome is
definitely the largest biome out there. Water covers nearly 75 percent of the earth's surface, in the form of ocean, lakes,rivers, etc.
Types of Aquatic Biomes
Fresh water regionsMarine water regions
Fresh water regions is defined as having a
low salt concentration—usually less than 1%.
Marine water regionsis the biggest biome in the world.
Types of fresh water regions
Lentic-still water
Lotic - running water
Three Fresh water zones
Ponds and Lakes Streams and Rivers Wetlands
Ponds and LakesPonds are often
seasonal, meaning they created in the rainy season. Lakes will often survived for hundreds of years.
Zones of Ponds and Lakes
Littoral zone Limnetic zone Profundal zone Benthic zone
Littoral zone which closest to the shore is a host to a
wide variety of species due to to its warm, shallow environment.
Limnetic zonethe near-surface open
water surrounded by the littoral zone.
Profundal zoneis the deeper region of
ponds or lakes.
Benthic zonevery bottom of the
floor.
Rivers and Streams These are bodies of flowing water moving in one direction. Streams and rivers can be found everywhere—they get their starts at headwaters, which may be springs, snowmelt or even lakes.
Wetlands are area of standing
water that support aquatic plants.
Aquatic Biomes
Three major groups of organisms in Marine Region
BenthosNekton Plankton
BenthosPlants such as kelp and
animals such as brittle fish that live on or depend on the bottom
Nekton swimming animals such as
fishes and whales that moves independ
ently of water currents.
Plankton are very small organisms
that live in the world's oceans.
Three regions of Marine Aquatic Biomes
Ocean Coral Reefs Estuaries
Ocean represents the largest
and most diverse of the ecosystem.
Four main zones of the OceansInter-tidal -the ocean connects to the landPelagic zone
-out in the open ocean which is host to many species of fish and marine mammals.
Benthic zone-or deep sea, and is host to silt sand
and slowly decomposing organisms.Abyssal zone
-deepest part of the ocean.
Coral reefs are underwater structures
made from calcium carbonate secreted by corals.
Estuaries is a partly enclosed coastal
body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea.
