Q. The abrupt change or junction between two ecological zones is termed as

(A) Ecological niche

(B) Ecosystem

(C) Ecotype

(D) Ecotone

Ans: Ecotone

Explanation:

An ecosystem is a biological community of interacting organisms and their physical environment. An ecological niche is the role and position a species has in its environment; how it meets its needs for food and shelter, how it survives, and how it reproduces. A species’ niche includes all of its interactions with the biotic and abiotic factors of its environment. An ecotype is a distinct form or race of a plant or animal species occupying a particular habitat. An ecotone is a transition area between two biomes. It is where two communities meet and integrate. It may be narrow or wide, and it may be local (the zone between a field and forest) or regional (the transition between forest and grassland ecosystems).
