C. Fast
D. Accelerated - correct answer ✔✔A. slow
How does having a large number of offspring affect a parent's fitness for subsequent breeding
seasons?
A. It could limit the number of offspring the adult produces in its life.
B. The increased energy needed to feed many offspring may lower adult survival in the following
breeding season.
C. The energy required to feed many offspring could trigger smaller broods in the future.
D. Competition with offspring for food could reduce energy for future reproduction. - correct
answer ✔✔B. The increased energy needed to feed many offspring may lower adult survival in
the following breeding season.
When adults have a high probability of survival from one year to the next and offspring survival
is relatively poor, the best strategy for an adult to maximize fitness is to _______.
A. increase fecundity at the expense of survival
B. delay reproduction for the next cycle
C. increase survival at the expense of fecundity
D. invest all excess energy in having fewer but larger offspring - correct answer ✔✔C. increase
survival at the expense of fecundity
, For birds, age at maturity ________.
A. varies directly with annual survival rates of adults
B. varies inversely with annual survival rates of adults
C. varies with the productivity of the environment
D. is not related to annual survival rates of adults - correct answer ✔✔A. varies directly with
annual survival rates of adults
What is the reproduction pattern of most insects?
A. Semelparity

D. Perennial - correct answer ✔✔A. Semelparity
Lobelia telekii and its relative, L. keniensis, both grow on Mount Kenya in Africa. L. telekii grows
on dry rocky slopes whose resources for reproduction (particularly moisture) are highly variable
in time and space. L. keniensis is found in moist valley bottoms with more stable moisture
supplies. Which species is semelparous?
A. L. telekii
