Exponential vs. Logistical Flashcards
How is population growth determined?
Experimenting and taking samples of a population over time.
An exponential graph can be drawn with…
An accelerating upward line.
A logistical graph can be drawn with…
An accelerating then decelerating line.
Where is population growth the highest on an exponential graph?
At the top.
Where is population growth the highest on a logistical graph?
In the middle.
What happens to a graph when r is changed?
The line gets steeper because the popuation could grow more than it could before.
What happens to a graph when N0 is changed?
The line gets steeper because there are more organisms in the population to reproduce and grow.
What happens to a graph when K is changed?
The line decelerates faster because it has a smaller maximum.
