Front 1

Biomes:

Back 1

Areas sharing similar climate, topographic and soil conditions, and roughly comparable communities.

Front 2

How many Biomes are there?

Back 2

9

Front 3

Name the Nine Biomes.

Back 3

Tropical rainforest, Temperate rainforest, Tropical seasonal forest, temperate forest, Taiga, tundra, Woodland grassland shrubland, Thorn forest Savanna thorn scrub, Desert.

Front 4

Tropical Rainforest:

Back 4

belong to the tropical wet climate group. Almost all lie near the equator. cover less than 6% of land surface

Front 5

Temperate Rainforest:

Back 5

made up of evergreen conifers. have one long wet season and a fairly dry summer(fog).mild coastal climate

Front 6

Tropical seasonal forest:

Back 6

densely growing trees which lose their leaves during dry season.found between tropical rainforests and savanas.

Front 7

Temperate forest:

Back 7

deciduous forests, lose their leaves in the winter, four definate seasons

Front 8

Taiga:

Back 8

Large portion of Canada, Euroope and Asia. below freezing for six months of the year, warm, humid summer months.

Front 9

Tundra:

Back 9

coldest of all the biomes, treeless, Low biotic diversity
Simple vegetation structure
Limitation of drainage
Short season of growth and reproduction
Energy and nutrients in the form of dead organic material
Large population oscillations

Front 10

Savanna:

Back 10

olling grassland scattered with shrubs and isolated trees, which can be found between a tropical rainforest and desert biome. warm temperature year round. There are actually two very different seasons in a savanna; a very long dry season (winter), and a very wet season (summer)

Front 11

Desert:

Back 11

cover about one fifth of the Earth's surface and occur where rainfall is less than 50 cm/year.

Front 12

Woodland, grassland, shrubland:

Back 12

High altitude, Hot and dry in the summer, cool and moist in the winter

Front 13

Biodiversty:

Back 13

Variety of living things.(3 types)

Front 14

Gentic diversity:

Back 14

Measures variety of different versions of same genes in a species.

Front 15

Species Diversity:

Back 15

Measures # of differnt kinds of organisms within a community.

Front 16

What is Ecological Diversity:

Back 16

Measures richness and complexity of a community.

Front 17

Benefits of biodiversity:

Back 17

Food- nearly 80000 edible wild plants we could utilize. Natural products used in medicine

Front 18

Ecological benefits:

Back 18

Soil formation, waste disposal, air and water purification, solar energy absorbtion, and biogeochemical and hydrological cycles.

Front 19

Threats to Biodiversity:

Back 19

Extinction, habitat destruction (human caused, over hunting/fishing, smuggleing

Front 20

extinction:

Back 20

Elimination of a species.

Front 21

Endangered Species Act:

Back 21

ESA(1973) regulates wide range of activites involving endangered species. Like, "taking", selling, importing/exportomng.

Front 22

Endangered:

Back 22

those animals considered in imminent danger of extinction.

Front 23

Threatened:

Back 23

animals likely to become endangered, at least locally, in the near future.

Front 24

Vulnerable:

Back 24

Animals that are naturally rare or have been locally depleted to a level that puts them at risk.

Front 25

Recovery Plans:

Back 25

once a species is listed as endangered a plan is put into oreder to rebuild the species. Total cost for all animals= $5 billion

Front 26

CITES:

Back 26

Convention on International Trade in Endangered Species(1975)Regulate trade in living specimens and products derived from listed species.
