Metabolism And Survival (Key Area 5) Flashcards
What decreases during dormancy?
Metabolic rate, heart rate, breathing rate and body temperature.
Why must the metabolic rate be decreased during dormancy?
To save energy.
Many environments vary beyond the _____________ ______________ for normal metabolic activity for any particular organism.
Tolerable limits
Some animals have ___________ to ___________ these adverse conditions while others ___________ them.
Some animals have ADAPTED to SURVIVE these adverse conditions while others AVOID them.
Dormancy can be __________ or __________.
Predictive or consequential
Predictive dormacy occurs…
Before the onset of adverse conditions.
Consequential dormacy occurs…
After the onset of adverse conditions.
What type of dormacy allows mammals to survive adverse conditions during winter/ cold temperatures without avoiding them?
Hibernation
What type of dormacy allows mammals to survive periods of high temperature or drought?

________ _________ is a period of reduced activity in some animals with high metabolic rates.
Daily torpor
How do some species avoid adverse conditions?
Migration
Why do organisms migrate?
To relocate to a more suitable environment.
What is an issue with migration?
