population growth for microorganisms

• what does a population growth graph over time look like

  
• what is the order of phases in s population growth for microorganisms


  lag, log, stationary and death
• what is meant by the lag phase in the population growth for microorganisms


  this is the phase when there is no/ little cell division , and intense metabolic activity such as enzyme synthesis
• what is meant by the log phase in the population growth for microorganisms


  this is the phase in which there is a rapid increase in numbers , and there is no limiting factors to growth
• describe the death rate to cell division during the log phase


  cell division > death rate
• what is meant by the stationary phase in the population growth for microorganisms


  this is a phase when there are limiting factors preventing the further growth of the population
• what is meant by carrying capacity


  the number of organisms a given region or habitat can support without degrading the environment
• what is meant by the death phase in the population growth for microorganisms


  this is a phase where limiting factors cause the populations size to decrease
