Population growth
... Use the data to plot a line graph of time (on the horizontal axis) against the number of yeast cells (on the vertical axis). Describe the shape of the graph. Explain and give reasons for the population pattern from days 1-6. Explain what might have caused the change in the growth pattern ...

Environment and Organisms
... Growth rate can be positive (more in the population than before), negative (less in the population than before) or zero (no change). Density of a population is the number of organisms per unit area; the more organisms living in a given amount of space, the denser the population in that space. ...
