AP Biology· difficulty 2/5

Resource partitioning allows similar species to coexist by

  • A

    Using slightly different parts of the resource (e.g., different food sizes, foraging at different times or heights)

  • B

    Switching to identical resources but cycling use across alternating seasons or annual reproductive bouts

  • C

    Hybridizing repeatedly until the formerly distinct species merge into a single interbreeding population

  • D

    Driving the weaker competitor extinct so a single dominant species fully exploits the contested resource

Explanation

Subtle differences (vertical strata in trees, prey size) allow coexistence by avoiding direct competition.
