metabolism and adverse conditions

• how do organisms survive adverse conditions?

  dormancy
• during dormancy, what decreases?

  metabolic rate, heart rate, breathing rate and body temp
• dormancy is a part of some organisms life cycle, to allow...?

  survival during a period when the costs of continued normal metabolic activity would be too high.
• why can the metabolic rate be reduced during dormancy?

  to save energy
• what are the two types of dormancy?

  predictive and consequential
• when does predictive dormany occur?

  before onset adverse conditions
• when does consequential dormancy occur?

  after onset adverse conditions
• how do some mammals survive during winter/low temperatures

  hibernation
• what does aestivation allow?

  survival in periods of high temperature or drought
• what is daily torpor a period of?

  reduced activity in some aniamls with high metabolic rates
• how can animals avoid adverse conditions

  migration
• explain migration


  avoiding metabolic adversity by expanding energy to relocate to a more suitable enviroment
• name the two types of migratory behaviour

  innate and learned
• specialised techniques are used to study long distance migration - give examples


  satellite tracking and leg ringing
