Biodiversity

Question 1

Subtidal Kelp Bed communities are the —-primary productivity of all community’s on the planet

Answer 1

highest
-also provides shelter for species
-and provides protection

Question 2

Greatest species diversity of vertebrates on plants
highly efficient recycling of nutrient

Answer 2

Coral reefs

zooxanthellae

Question 3

Difference between the Arctic and Antarctic?

Answer 3

Arctic is ocean surrounded by land has great diversity becuase of large rivers flowing into ocean, have terrestrial predators.

Antarctic island, very small diversity-penguins, have water predators-orca

Question 4

Dystrophic

Answer 4

tea colour lakes low productivity

Question 5

Intermediate productivity lakes

Answer 5

mesotrophic

Question 6

Eutrophic

Answer 6

high productivity lakes

Question 7

Tundra

Answer 7

3-6 months darkness
permafrost-frozen all year deep ground
shrubs
lots of insects

Question 8

Temperate rainforest
-taiga or boreal forest

Answer 8

west coast
ancient trees

Question 9

Tropical forest

Answer 9

6 strata
-a) discontinuous sympodial growth not monopodial(spruce tree shape)
b) continuous lower trees

ground and tall trees connected by vines- Lianas

Question 10

Amount of nitrogen in terrestrial community’s

Answer 10

arctic most
taiga lots
deciduous forest/grassland med
savannah/ equatorial forest low

Question 11

Hot moist air rises creating a —-clouds

Answer 11

cumulus

Question 12

Hadley cell

Answer 12

by equator

Question 13

Global trends for biodiversity?

Biomass

Answer 13

Marine=6
terrestrial=470
deep surface=70

Question 14

Biodiversity Global trends

Latitudinal Diversity Gradient

Answer 14

Most fish at equator the goes down towards the poles

Question 15

Biodiversity Global trends, Oceanic depth, which depth is most diverse?

Answer 15

intermediate depth 2000-3000m

Question 16

Why is the Arctic high productivity but low species richness?

Answer 16

The species dont have to adapt to nutrients around them becuase there is so much

different in equator with low productivity by high species richness becuase they have to adapt to the limiting resources

Question 17

The terrestrial primary production is largely due to

Answer 17

temperature and rainfall

Question 18

the competition theory about global species richness is?

Answer 18

In temperate latitudes has less species with broader niches creates a jump in productivity in June

while in tropics lots of k species with limited resources

Question 19

The more surface area would result in higher number of diversity is called—- in global trends in species richness

Answer 19

spatial heterogeneity theory

Question 20

Rivet hypothesis

Answer 20

each species lost slowly decreases stability
then drops when gets to low

Question 21

Passenger hypothesis

Answer 21

A keystone species control the whole system
