- multigenerational cohabitation
- intrasexual selection
- all are characteristic of eusociality
A: intrasexual selection

Q: Fecundity is
- the quantity of feces produced by an individual
- the number of prey an organism ingests
- the amount of energy allocated to capturing prey
- a measure that describes the size of eggs or seeds
- the number of eggs or seeds produced by an individual

Q: Male guppy coloration was determined by Endler to be influenced by
- intrasexual selection
- predation
- sexual selection by females
- both sexual selection by females and predation

- a high C:N ratio
- only N and no C
- only P and no C
- a low C:P ration
A: a low C:N ratio

Q: Researchers who examine the balance of nutrients and energy is affected by organisms and their interactions in the environment are studying
- systematics
- ecological stoichiometry
- phylogenetics
- demography
- biogeography
A: ecological stoichiometry

Q: Describe optimal foraging theory and give an example of how it has been tested.

Q: If the females of some species can reproduce parthenogenically, why do males persist in these species?
- to decrease the likelihood of infertility
- to increase the number of offspring produced
- to aid in protection and rearing of the offspring
- to increase genetic diversity of the offspring
- defense
A: to increase genetic diversity of the offspring

Q: Based on optimal foraging theory, a plant growing in a nitrogen poor soil will likely

- decrease root biomass.
- increase aboveground growth.
- have no impact on growth.
- do none of the above.
A: increase root biomass.

Q: The flowers of wild radish have both stamens and pistils, however, they are unable to pollinate themselves.  This condition is referred to as
- self-incompatibility
- parthenogenesis
- asexual reproduction
- inclusive fitness
- nonrandom mating
A: self-incompatibility

Q: Secondary sexual characteristics can be disadvantageous because of

- Animals
- Plants
- Fungi
