2.5 metabolism in adverse conditions

Question 1

Define what adverse conditions are

Answer 1

When the environment an organism is in goes beyond the tolerable limits to undergo normal metabolic activity

Question 2

How do organisms survive adverse conditions

Answer 2

• adapt

- avoid

Question 3

Define dormancy

Answer 3

When metabolic rate and physiological functions are slowed down for a period of time (become temporarily inactive)

Question 4

Why do organisms become dormant

Answer 4

• reduce the metabolic rate

- avoid wasting energy

Question 5

Define predictive dormancy

Answer 5

Where an organism becomes dormant before the adverse conditions arrive

Question 6

Define consequential dormancy

Answer 6

Where an organisms becomes dormant after the adverse conditions arrive

Question 7

Define hibernation

Answer 7

Dormancy in animals

Question 8

When does hibernation take place

Answer 8

In conditions with extremely low temperatures (winter)

Question 9

Define aestivation

Answer 9

Form of consequential dormancy by some animals

Question 10

When does aestivation take place

Answer 10

Extremely hot conditions and drought

Question 11

define daily torpor

Answer 11

-an animals metabolic rate and activity is greatly reduced for a certain part of every 24h cycle

Question 12

Define migration

Answer 12

-the movement of an animal from one location to another during specific seasons to avoid adverse conditions
