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.
