What is the primary focus of organismal ecology?

The study of the mechanisms responsible for changes in the distribution and abundance of individuals within a population over space and time

The study of how organisms recolonize or repopulate an area after a disturbance

The study of the interactions between populations of different species that inhabit a particular area

The study of the behavioral, physiological and morphological ways in which individual organisms meet the challenges posed by their abiotic environment (correct)

What limits the distribution of organisms according to the passage?

The abiotic conditions they can tolerate (correct)

The occurrence of periodic disturbances like fire

The size of the geographic area they inhabit

The abundance of other species in the community

How does population ecology differ from community ecology?

Population ecology is a subfield of community ecology, which studies the interactions between populations

Population ecology studies the mechanisms behind changes in abundance, while community ecology studies periodic disturbances

Population ecology studies the distribution of organisms, while community ecology studies the abiotic environment

Population ecology focuses on a single species, while community ecology focuses on multiple species (correct)
