Ecotone is a

Your answer: —  Â·  Correct: B

Explanation

An ecotone is defined as a zone of junction or a transitional area between two or more diverse ecosystems. It is the interface where two different biological communities meet and integrate. Common examples include:

  • Mangroves: Transition between terrestrial and marine ecosystems.
  • Estuaries: Transition between fresh water and salt water.
  • Grasslands: Transition between forests and deserts.

Ecotones often exhibit the edge effect, where the variety and density of organisms are greater than in either of the adjacent communities. While an ecotone is often diversified, the term "transitional ecosystem" is the technically accurate definition used in ecology. Terms like "transparent" or "stagnation" do not apply to the functional definition of an ecotone.
