Based on Figure 53.10 and the accompanying text, which of the following statements accurately compares the growth patterns of Paramecium and Daphnia in relation to the logistic model?

  • A: Both *Paramecium* and *Daphnia* populations perfectly fit the logistic growth model, showing smooth S-shaped curves.
  • B: *Paramecium* growth closely approximates the logistic model, while *Daphnia* shows fluctuations and overshoots carrying capacity.
  • C: *Daphnia* growth closely approximates the logistic model, while *Paramecium* shows significant delays before reaching carrying capacity.
  • D: Neither *Paramecium* nor *Daphnia* populations fit the logistic growth model well, as both exhibit substantial fluctuations.

Explanation

Figure 53.10a and its caption state that Paramecium growth in a small culture closely approximates logistic growth. In contrast, Figure 53.10b and its caption explain that Daphnia population growth does not correspond well to the logistic model, as it overshoots the carrying capacity and then settles to an approximately stable size, indicating fluctuations.
