Question

Interpret the model of population growth in a population of dandelions.

Drag "True" or "False" to the end of each statement.

A. You can infer from this curve that the sunlight, nutrients, water, and space available to the dandelions are plentiful (that is, are not limiting population growth). (True or False)

B. The value of r is higher after three months than after one month. (True or False)

C. More dandelions are reproducing after three months than after one month. (True or False)

D. Population growth is exponential. (True or False)

E. Each dandelion is producing more seeds after three months than after one month. (True or False)

F. The slope of the curve is steeper after three months than after one month. (True or False)

Answer 1

Remember that the curve shows the population size (number of dandelions), not the reproductive rate.

A. True - if anything were limiting the growth you would see the curve flatten out or decrease

B. False - r is generally the same for a given species and doesn't change month to month

C. True - the babies from the first month have grown up and are making their own seeds (you can see that the number of dandelions has increased, so we can assume that more are available to reproduce)

D. True - this graph shows exponential growth

E. False - individuals will maintain the same reproductive rate, so one plant can't produce more seeds later on than it could at the beginning

F. True - slope is the rate of change - the graph is going up faster at 3 months than it was at 1 month

Hope that helps!
