What are the Major Types of Ecosystems?

Aquatic Ecosystems

These are the Freshwater Ecosystems such as river, stream, lake, pond and swamp. Also the Marine Ecosystem such as marsh, estuary, mangrove forest, seagrass bed, kelp forest

What are the Example of Terrestrial Ecosystems?

Salt Marsh

Salt Water and Fresh Water mix in _____________. Cordgrass (Spartina) is the dominant vegetation in this salt marsh at Assateague Island National Seashore, Maryland.

Cordgrass

_________________ (Spartina) is the dominant vegetation in this salt marsh at Assateague Island National Seashore, Maryland.

Marsh

It is a wetland ecosystem characterized by soft stemmed plants like grass near the coast or along rivers.

Marsh

It can be freshwater or salty depending on the location and water source.

Estuary

It is an area where a freshwater river or stream meets the ocean. When freshwater and seawater combine, the water becomes brackish, or slightly salty.

Estuary

They often have a mix of freshwater and salt-tolerant plants like mangroves, salt marshes and seagrasses.

Mangrove Forest

They are coastal forests and critical habitats that act as nurseries and protect

Mangrove Forest

They are characterized by halophytic (salt loving) trees, shrubs and other plants growing in brackish to saline tidal waters.

Halophytic Trees

Mangrove Forest are characterized by _______________, shrubs and other plants growing in brackish to saline tidal waters.

Seagrass Bed

It is an underwater ecosystem formed by seagrasses. Seagrasses are marine (saltwater) plants found in shallow coastal waters and in the brackish waters of estuaries.

Seagrass Meadow

Seagrass Bed is also known as?

Kelp Forest

They are underwater ecosystems formed in shallow water by the dense growth of several different species known as kelps.

Kelp Forest

Some species can reach heights (underwater) of 150 feet (45 m), and under ideal physical conditions, kelp can grow 18 inches (45 cm) in a single day!

Kelp Forest

As a result of this incredible growth, _________ can develop very quickly in areas where they did not previously exist.

Algae

They are photosynthetic (food and oxygen sources). They have simple structures and lack roots, stems and leaves. Example are seaweed

extremely large brown algae

Though they look very much like plants, kelps are actually _____________________________

Terrestrial Ecosystem

It is a land-based community of organisms and the interactions of biotic and abiotic components in a given area.

Temperature, Precipitation

These are important abiotic factors that influence biome distribution in Terrestrial Ecosystem

Tundra Ecosystem

They are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant

Tundra Lands

They are covered with snow for much of the year, but summer brings bursts of wildflowers.

Taiga

________, also called boreal forest, vegetation composed primarily of cone-bearing needle-leaved or scale-leaved evergreen trees, found in northern circumpolar forested regions characterized by long winters and moderate to high annual precipitation.

Boreal Forest

Taiga is also known as?

Temperate Deciduous Forest

These are a variety of temperate forest 'dominated' by trees that lose their leaves each year.

Temperate Rainforest

They are coniferous forests that occur in the temperate zone and receive heavy rain.

Temperate Grassland

They are areas of open grassy plains that are sparsely populated with trees.

Temperate Grassland

They can be found in various regions north and south of the equator including Argentina, Australia, and central North America.

Pampas, Downs, Veldts

What are the various names of temperate grasslands?

Temperate Grassland

It is well suited to growing grain crops.

Tropical Grasslands

It has widely scattered trees interspersed with grassy areas. It occurs in tropical areas with low or seasonal rainfall.

Savanna

Tropical grasslands are also known as?

Deserts

They are found in both temperate (cold desert) and subtropical or tropical regions (warm desert) with low levels of precipitation, contains organisms with specialized water-conserving adaptations.

Temperate Deserts

They are found in the latitudes between tropical and polar regions. They typically have similar aridity to and lower temperatures than tropical deserts..

Tropical Deserts

It is an environment of extremes: it is the driest and hottest place on earth. Rainfall is sporadic and in some years no measurable precipitation falls at all

Tropical Rainforest

It is a forest occurring in tropical areas of heavy rainfall. It is abundant with many species of wildlife and vegetation.

Tropical Rainforest

They have high species diversity.

Tropical Rainforest

They are mainly located between the latitudes of 23.5°N (the Tropic of Cancer) and 23.5°S (the Tropic of Capricorn)—the tropics.

Tropical Rainforest

They are found in Central and South America, western and central Africa, western India, Southeast Asia, the island of New Guinea, and Australia.
