Metabolism and Adverse Conditions

Question 1

Describe how environments vary on a particular organism

Answer 1

Many environments vary beyond the tolerable limits for normal metabolic activity for a particular organism

Question 2

How do animals react to adverse conditions?

Answer 2

Adapt or avoid for survival

Question 3

Describe dormancy

Answer 3

Part of some organisms’ lifecycle to allow survival during a period when the costs of continued metabolic activity would be too high

Question 4

Describe what happens during dormancy

Answer 4

There is a decrease in metabolic rate, heart rate, breathing rate and body temperature

Question 5

What can dormancy be?

Answer 5

Predictive or consequential

Question 6

Explain predictive dormancy

Answer 6

It occurs before the onset of adverse conditions

Question 7

Explain consequential dormancy

Answer 7

It occurs after the onset of adverse conditions

Question 8

How can some mammals survive winter/low temperatures?

Answer 8

Hibernation

Question 9

Explain aestivation

Answer 9

Allows survival in periods of high temperature and drought

Question 10

Describe Torpor

Answer 10

A period of reduced activity in some organisms with high metabolic rates

Question 11

How does migration avoid adversity?

Answer 11

By expending energy to relocate to a more suitable environment

Question 12

What can migratory behaviour be?

Answer 12

Innate or learned

Question 13

Describe specialised techniques in studies of long distance migration

Answer 13

Satellite tracking

Leg rings

Question 14

Describe leg rings

Answer 14

Animals have to be captured then recaptured
Only shows start and end locations
Cheap

Question 15

Describe satellite tracking

Answer 15

Expensive
Can see whole migratory cycle
Doesn’t need recaptured
