In Biology, what are limiting factors? B. Give THREE examples of limiting factors that affect bacterial growth. 2. Using the blank graphs on your BW answer sheet, draw what the graph line would look like over time if A. Bacteria had limiting factors that affected their growth. B. Bacteria had no limiting factors (unlimited bacteria growth).
Understand the Problem
The question is asking for an explanation of limiting factors in biology and examples that affect bacterial growth, as well as a graphical representation of bacterial growth under two different conditions. The focus is on identifying biological concepts and illustrating effects on growth.
Answer
Limiting factors limit growth. Examples: temperature, pH, nutrients. Graphs: logistic curve (limited), exponential curve (unlimited).
Limiting factors in biology are conditions that limit the growth, abundance, or distribution of an organism. Examples for bacteria include temperature, pH, and nutrient availability. With limiting factors, bacterial growth will show a logistic curve; without them, it would show an exponential curve.
Answer for screen readers
Limiting factors in biology are conditions that limit the growth, abundance, or distribution of an organism. Examples for bacteria include temperature, pH, and nutrient availability. With limiting factors, bacterial growth will show a logistic curve; without them, it would show an exponential curve.
More Information
Limiting factors such as temperature, pH, and nutrient availability can restrict bacterial growth significantly. When these factors are absent or optimal for growth, bacteria can reproduce at a rapid, exponential rate until resources become limiting.
Tips
A common mistake is assuming exponential growth will continue indefinitely. Remember, environmental factors eventually limit growth, leading to a logistic growth pattern.
