“Organism’s requirements and tolerances” for an ecological niche summarizes. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Habitat describes where an organism occurs; niche additionally describes how it obtains resources and affects or responds to other organisms. Distribution therefore provides evidence about a niche but is not identical to it. The remaining alternatives—“Only environmental tolerances”, “Population density”, “Genetic variability”—refer to different states, processes, or scales

“Behavioral adaptations” for ecological niche' can include. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names.

Habitat Niche

A niche primarily describes:

“How an organism interacts with its environment” for a niche primarily describes. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Habitat describes where an organism occurs; niche additionally describes how it obtains resources and affects or responds to other organisms. Distribution therefore provides evidence about a niche but is not identical to it. The remaining alternatives—“The place where an organism lives”, “Only abiotic factors”, “Only biotic factors”—refer to different states, processes,
