Metabolism in Conformers and Regulators Flashcards
What does adverse mean?
harmful or negative
What is the advantage of lowering metabolic rate during adverse condidtions?
It saves energy
What happens during dormancy?
The animal reduces it’s breathing rate, heart rate, metabolic rate and temperature.
State the 3 types of dormancy.
hibernation, aestivation & daily torpor
What do we call a period of dormancy in mammals associated with cold temperatures/winter?
hibernation
What do we call a period of dormancy associated with hot or drought conditions?
aestivation
Which organisms carry out daily torpor?
Animals with high metabolic rates
What is predictive dormancy?
Occurs before the onset of the adverse consitions
What is consequential dormancy?
After the onset of the adverse conditions
What is an advantage of consequential dormancy?
can remain active longer and exploit resources
What is a disadvantage of consequential dormancy?
sudden, severe change in the environment could kill organisms
What is migration?
The regular movement by members of the same species from one place to another over a relatively long distance
Why do organisms migrate?
To avoid metabolic adversity by expending energy to relocate to a more suitable environment
Which type of migratory behaviour is inherited and inflexible?
innate
Name the 2 factors that influence migratory behaviour.
innate and learned
