Beetle Survival The survival rates of three stages in the development of a flour beetle (egg, pupa, and larva) as a function of the relative humidity are shown below. (Source: Adapted from R. N. Chapman, Animal Ecology, New York: McGraw-Hill, 1931)

Fill in each of the following blanks with the appropriate stage: eggs, pupae, or larvae.

a. At 60% relative humidity, the rate of change of the survival rate of _______ and _______ is positive.

b. An increase in relative humidity above 60% improves the survival rate of _______ and reduces the survival rate of _______.

c. At 97% relative humidity, the tangent to the _______ survival curve has more negative slope than the tangent to the _______ survival curve.

d. Any tangent lines drawn on the survival curve for _______ will have negative slope.

e. The slope of the survival curve for _______ is always positive.

f. At 30% relative humidity, the slope of the survival rates for _______ and _______ are nearly equal.

g. At 65% relative humidity, the survival rates for _______ and _______ have approximately the same slope.
