Bio 101 Notes On Biomes

Front 1

What two biomes is the Earth split into?

Back 1

-Terestrial
-Aquatic

Front 2

Ecosystem

Back 2

Has to be self-contained. It looks at the interaction between the biotic (living) and the abiotic (non-living)

Front 3

Community

Back 3

Interested in the organisms and how they interact with each other

Front 4

Population

Back 4

Work with a single species of an organism. More informative if you look at one species in different environments. Need to be watching for evolution

Front 5

Niche

Back 5

The sense of conditions necessary for a species to survive

Front 6

Tundra

Back 6

Plants tend to be on the short side. Characterized by plants with a short life cycle because snow will disapear in the end of June, then will show up again toward the end of August.

Front 7

Permafrost

Back 7

Permanently frozen under the surface.

Front 8

Taiga (Coniferous Forest)

Back 8

Evergreens-can do a little bit of photoynthesis, even in the dead of winter. They are frost resistant.

Front 9

Temperate Forest (Deciduous)

Back 9

They are dominated by trees that loose their leaves each fall.

Front 10

Temperate Forest (Coniferous)

Back 10

Have evergreen trees.

Front 11

Temperate grassland

Back 11

Bison once dominated the North American prarie.

Front 12

Tropical Savannah

Back 12

Is home to grasses, scattered trees.

Front 13

Prarie

Back 13

30-35 inches of rain per year.
Temp. ranges are about the same, but when it reaches a certain temp. it tends to stay there for awhile.
Moisture- snow, rain, they dry.
Means the fire hazard signs will be very high.

Front 14

Deserts

Back 14

Less than 4 inches of rain/year.
Characterized by plants that hang around (cactus).
Temp.- can get nasty, can be cold all the time, but can also be really hot.
When it rains, it rains- flash floods.
Organisms need to be highly adaptive to their environment.

Front 15

Cactus

Back 15

Germinate like crazy.
Have to wait till it rains.

Front 16

Tropical Rain Forest

Back 16

Large numbers of niches.
Mostly in northen South America.
Seriously dense!

Front 17

Biodiversity

Back 17

All sorts of plants.
More orchids than any other species because they will grow in tropical rain forests.

Front 18

Producers

Back 18

Anything that does photosynthesis.
Plants= Primary producer.

Front 19

Consumers

Back 19

Consume energy.
Herbivores- animals that eat plants, are secondary producers.

Front 20

Decomposers

Back 20

Eat the little bits.
They are bacteria and fungi.
They put all the carbon dioxide back into the atmosphere.
