2. What is the calculation to work out birth rate?

  • number of population - original population
  • no of births / no of adults X 100
  • no of births per year / total population X 1000
  • no of births per year / total population X 100

3. Best sampling methode to use when looking at succession?

  • Systematic belt transect
  • Random quadrate
  • Line transect
  • Point quadrate

4. How does temperature effect population size?

  • Too cold increases metabolic rate = increase population
  • Too cold denatures enzymes ( change active site) = decrease population
  • Too hot means denature of enzymes = decrease population
  • Too hot means more kinetic energy for enzymes = increases population

5. An assumption of mark release recapture?

  • Sample is 100% of population
  • Sample is 30% of population
  • Sample is 50% of population
  • Sample is 10% of population
