Concept explainers
a.
To describe: The factor (dispersal) that ecologists examine to understand the geographic distribution of a species.
Introduction: Biogeography is defined as the study that deals with the geographic distribution of ecosystem and species. The species distribution indicates the evolutionary and ecological interactions with biotic and abiotic factors. There are four factors used by ecologists in order to examine the geographic distribution of species, dispersal, habitat selection, behavior, biotic factors, and abiotic factors.
b.
To describe: The factors (habitat selection and behavior) that ecologists examine to understand the geographic distribution of a species.
c.
To describe: The factor (biotic) that ecologists examine to understand the geographic distribution of a species.
d.
To describe: The factor (abiotic) that ecologists examine to understand the geographic distribution of a species.
