U2 KA5 Metabolism And Adverse Conditions

Question 1

What happens when environments vary beyond the tolerable limits for an organism’s metabolic activity?

Answer 1

Some animals adapt to survive these conditions, while others avoid them.

Question 2

What is dormancy in the context of surviving adverse conditions?

Answer 2

Dormancy is a period in an organism’s life cycle that allows survival when the costs of normal metabolic activity are too high. The metabolic rate is reduced to save energy.

Question 3

How does dormancy help organisms survive adverse conditions?

Answer 3

Dormancy helps organisms survive by reducing their metabolic rate and conserving energy during unfavorable conditions.

Question 4

What are the two types of dormancy?

Answer 4

Predictive dormancy and consequential dormancy.

Question 5

How do some mammals survive winter or low temperatures?

Answer 5

They survive by hibernating, which is a form of dormancy.

Question 6

What is aestivation?

Answer 6

Aestivation is a form of dormancy that allows survival during periods of high temperatures or drought.

Question 7

What is daily torpor?

Answer 7

Daily torpor is a period of reduced activity that some animals with high metabolic rates enter to conserve energy.

Question 8

How do some animals avoid adverse conditions?

Answer 8

By migrating to a more suitable environment.

Question 9

What is the energy cost of migration?

Answer 9

Migration requires expending energy to relocate to a more favorable environment.

Question 10

Can migratory behavior be learned?

Answer 10

Yes, migratory behavior can be both innate and learned.

Question 11

What is used to study long-distance migration?

Answer 11

Specialized techniques are used to study long-distance migration. such as ringing birds or tagging other mammals.
