* Bio-physical factors controlling terrestrial ecosystems.

Question 2

what are terrestrial biomes

Answer 2

a land region on the earth’s surface covered by biological communities that group under the same climatic patterns like rainfall and temperature.

Question 3

terrestrial biomes are distributed through VS

Answer 3

vertical stratification

Question 4

what is vertical stratification

Answer 4

forests will generally contain multiple layers
upper canopy
upper middle and shrub understory

Question 5

examples of terrestrial environments

Answer 5

tropical forests
savanna
deserts
chaparral
tundra

Question 6

tropical forests

Answer 6

generally hot, wet conditions
canopy is often closed less than 1 percent reaches the forest floor
soils are often nutrient poor but nutrients recycled highly efficiently

Question 7

savanna

Answer 7

comprise of a mixture of grasses and trees dry climatic conditions
dominant plant species are fire adapted

Question 8

deserts

Answer 8

occur primarily in regions of low rainfall
temaptures can be variable however hot and cold deserts exist

Question 9

chaparral

Answer 9

mild rainy waters long hot dry summers
common landscape in the mediterranean region

Question 10

temperate grassland

Answer 10

grass dominate with sporadic presence of trees
moderate rainfall punctured

Question 11

coniferous forest

Answer 11

widely distributed in cold regions of the northern hemisphere
the largest trees in the world are coniferous

Question 12

bio factors atmosphere

Answer 12

soil , water avilibilty, temptature, sunlights

Question 13

soil

Answer 13

The quality and the amount of soil are critical for determining the size, health and biodiversity of a terrestrial ecosystem.
* Certain parameters, such as pH, have a fundamental effect on species assemblage.
* Soil can be further divided and considered as a number of layers:

Question 14

water availibilty

Answer 14

affected by soil type
seeping water dissolves and transports organic matter and minerals lower in the soil

Question 15

tempature

Answer 15

can influence both abiotic and biotic factors

Question 16

sunlight

Answer 16

Ecosystems closer to the equator receive more sunlight.
* Southern and northern regions receive more fluctuation in sunlight.
* Landscape features can reduce sunlight levels.
* Plants (ie. Tree foliage) can reduce sunlight for understory.
* All influence abiotic and biotic components.
