Answer 8

local or within habitat

Question 9

Question 11

functional diversity

Answer 11

concerns range of things that organisms do in communities and ecosystems

Question 12

which biome has the highest species richness

Answer 12

tropics

Question 13

where are larger amounts of mammals found

Answer 13

closer to the equator

Question 14

what are the hypotheses relating to latitudinal patterns in diversity

Answer 14

tropics are a cradle of diversity
tropics are a museum of diversity
ecosystem productivity drives species richness
global surface area

Question 15

tropics are a cradle of diversity

Answer 15

speciation rates are higher and more species are being born here

Question 16

tropics are a museum of diversity

Answer 16

extinction rates are lower and old species are harbored here

Question 17

global surface area

Answer 17

earth is bigger near the equator, so more species reside and evolve here

Question 18

causes of contemporary species loss

Answer 18

habitat loss, over-exploitation (hunting), species invasions (pathogens), climate change
