Question 9

Refer to the figure below, and then answer the question that follows. 
-What does the graph of Daphnia population growth suggest about this species?

Accepted Answer

The J-curve suggests that the species has a short generation time and is r-selected, meaning they have high reproductive rates but lower survivorship.

Question 10

A friend tells you that vintners use yeast that produce alcohol to turn grape juice into wine. He also observes that wine must still have living yeast in it because vintners don't pasteurize wine to kill the yeast. To make wine himself, he explains, he added wine to grape juice with the expectation that the yeast would turn the juice into wine. It didn't work, and your friend wonders why not. In terms of population ecology, what can you explain to your friend about the death of his yeast?
