Define a niche as a species’ role, including habitat, feeding and interactions within its community.
Compare species niches by food, predators, activity timing, nest sites or environmental conditions.
Ecologists studied the distribution of five species of insectivorous wood warblers of the genus Dendorica living on different parts of coniferous trees in mature forests.
Other than position in the tree, suggest two ways in which the niches of the warblers in the ecosystem may differ. 1: 2:
