Question

What is true of a behavior that has a small cost/benefit ratio? Select one O a. The behavior usually results in death. b. The behavior does not produce viable offspring. O c. The behavior decreases the organism's fitness O d. The behavior will usually be selected for. For the females of a species, which cost of mating and reproduction is likely to be greatest? Select one: a. attracting mates b. courtship displays c. gestation time O d. agonistic behaviors O Optimal foraging theory Select one: O a. is the concept that natural selection will favor animals that choose foraging strategies that maximize benefits while reducing costs. b. does not involve designing experiments that test whether or not an organism teeds randomly Oc. predicts that large prey items have considerable amounts of energy and require less time and energy to subdue. O d. predicts that the proportion of small to large prey eaten will not vary with the overall density of prey.

Explanation / Answer

1) The behaviour decreases the organism' fitness.As small benefit / cost ratio means that the benefit from foraging is smaller than the cost invested in searching the food which will affect the fitness of an orgnism.

2) gestation time is the greatest cost a female pay which comes under parental investment.

3) a) As optimum foraging means to search food in which cost should not be more than the benefit gained.
