2 species of butterflies Prezygotic - they can't even attempt to fertilize
live in the same
habitat/geographic
location but one is found
in the late spring, while
the other is only found in
the early autumn. What
type of reproduction
barrier is this?
,According to ideal free a. when the per capita benefit of the low quality
distribution, when would habitat increases to equal the per capita benefit of the
an organism be expected high quality habitat
to move into a low-quality
habitat?
a. when the per capita
benefit of the low quality
habitat increases to equal
the per capita benefit of
the high quality habitat
b. when a habitat corridor
exists between the two
habitats allowing
organisms to migrate from
one habitat to the other
c. when food availability in
the low quality habitat
increases to equal food
availability in the high
quality habitat
d. when the per capita
benefit of the high quality
habitat is greater than the
per capita benefit of the
low quality habitat
