2. AO1: Herbivores eat food with low nutrient content so have to eat more. Carnivores eat food with a high nutrient content so don't have to eat as often. This effects how long they can sleep for. This refers to which evolutionary explanation?

  • Waste of Time
  • Energy Conservation
  • Foraging Requirements
  • Predator Avoidance

3. AO2: Capellini (2008) looked at previous studies with standardised procedures and found that animals who sleep in exposed positions sleep less. This supports which explanation?

  • waste of time
  • foraging requirements
  • predator avoidance
  • energy conservation

4. AO2: Zepellin an Rechtstaffen (1974) found that small animals with a higher metabolic rate sleep more than large animals. This supports?

  • the waste of time explanation
  • the predator avoidance explanation
  • the energy conservation explanation
  • the foraging requirements explanation

5. AO2: Capellini (2008) looked at previous studies with standardised procedures and found that smaller animals with higher metabolic rates sleep less. This could be due to?

  • wanting to avoid predators
  • Foraging requirements
  • wanting to conserve energy
  • wanting to waste time
