Question

What is the transition zone between two ecosystems known as?
1. Ecotone
2. Ecotype
3. Biotope
4. Biome

Answer 1

Correct Answer - Option 1 : Ecotone

Topic	Description
Ecotone	An ecotone is a zone of junction or a transition area between two biomes (diverse ecosystems). Ecotone is the zone where two communities meet and integrate. For e.g. the mangrove forests represent an ecotone between marine and terrestrial ecosystems. This is the transition zone between two ecosystems
Ecotype	An ecotype is a variant in which the phenotypic differences are too few or too subtle to warrant being classified as a subspecies. These different variants can occur in the same geographic region where distinct habitats such as meadow, forest, swamp, and sand dunes provide ecological niches.
Biotope	A biotope is an area of uniform environmental conditions providing a living place for a specific assemblage of plants and animals.  Biotope is almost synonymous with the term habitat
Biome	A biome is a large naturally occurring community of flora and fauna occupying a major habitat. E.g. Rainforest biome or tundra biome.

Therefore it is clear that Ecotone is the transition zone between two ecosystems.
