Question

A transition area between two plant communities, where they meet and integrate, is called ___.

• A. ecotone
• B. niche
• C. habitat
• D. constance

Hint:

Think of the word's root: eco + tone, meaning tension zone between two ecosystems

Answer 1

The Correct Option is A

Step 1: An ecotone is defined precisely as the transition zone between two adjacent but different plant communities or ecosystems, such as the boundary between forest and grassland.

Step 2: Niche describes the functional role and resource use of a species, habitat describes the physical place where an organism lives, and constance is a term used in community studies for the frequency of occurrence of a species across samples, none of which describe a transition zone.

Step 3: Therefore the correct term is ecotone.
