KA5

Question 1

surviving adverse conditions

Answer 1

when organisms would need to survive beyond their metabolisms tolerable limit

Question 2

dormancy

Answer 2

period in life of an organisms during which metabolic activity, heart and breathing rate and body temperature is greatly reduced

Question 3

use of dormancy

Answer 3

allows survival during periods when metabolic costs would be too high

Question 4

predictive dormancy

Answer 4

organisms become dormant in advance of worsening conditions

Question 5

consequential dormancy

Answer 5

organisms become dormant after arrival of adverse conditions. Most adaptive where conditions are varied and unpredictable

Question 6

hibernation

Answer 6

when metabolic rate drops which allows body temperature to drop to surrounding temperature. Animal consumes extra food as fat store

Question 7

aestivation

Answer 7

the maintenance of moisture levels during high temperatures of periods of drought

Question 8

daily torpor

Answer 8

period of reduced activity in animals with high metabolic rates

Question 9

advantage to migration

Answer 9

avoids metabolic adverse conditions completely

Question 10

disadvantage of migration

Answer 10

expends energy

Question 11

two migratory behaviors

Answer 11

innate and leaned

Question 12

leaned migration

Answer 12

parent to offspring passing on knowledge

Question 13

innate migration

Answer 13

natural reaction to changes in external environment

Question 14

techniques to studying migration

Answer 14

satellite tracking, leg rings, tagging
