The phase where the death rate of microorganisms is faster than the reproduction rate; there are high concentrations of waste and low concentrations of nutrients.
death/decline
1 of 8
The phase where reproduction rates and death rates are balanced; nutrient levels are decreasing and waste levels are increasing.
stationary
2 of 8
The phase where organisms are adjusting to their surroundings. Population remains constant.
lag
3 of 8
The phase where population size is doubling with each new generation. The length of this phase depends on how fast they reproduce.
log/exponential
4 of 8
Primary metabolites are:
produced by an organism as part of its vital growth
5 of 8
The production curve of primary metabolites ________ the population curve of the organism
follows
6 of 8
Secondary metabolites usually:
have antibiotic properties
7 of 8
The production curve of secondary metabolites ________ the population curve of the organism
doesnt follow
