Question

Which best describes a fundamental niche, based on the barnacle example?

Group of answer choices

The actual tiny area a species occupies after competition

Only the area where a species is excluded by others

All possible areas a species can potentially live in without competition

The place where a species cannot survive at all

Answer 1

All possible areas a species can potentially live in without competition.

(Example: Connell's barnacle study showed Chthamalus could survive lower on the shore when competitors were removed — its fundamental niche is larger than its realized niche.)
