Question

model 3 - growth curves
diagram a - exponential growth curve
diagram b - logistic growth curve

1. refer to model 3

a. during what phase of the growth curves in each diagram is the population just beginning to colonize an area?
b. which type of population growth appears to continue unchecked?

1. the growth curves in model 3 are often referred to using the letters of the alphabet they resemble. the logistic growth curve is sometimes referred to as an s - curve. what letter would you use to describe the exponential growth curve?

Explanation:

• For part a, in population growth models, the lag phase is when the population is just starting to colonize an area as it is a period of adjustment and initial slow growth.
• For part b, exponential growth has no limiting factors (in the model shown) and continues to increase without check (represented by the J - shaped curve).
• For part 10, the exponential growth curve in the model has a shape similar to the letter J.

Answer:

a. Lag phase
b. Exponential growth

1. J
