Question

Which among the following is a correct definition of an Ecotone?
A. a transition between two types of ecosystems particularly plant communities.
B. a transition between two types of ecosystems particularly soil structure & chemical composition.
C. a transition between two types of mountain ranges.
D. a transition between two types of ecosystems such as water and land.

Answer 1

Vegetation between 2 totally different plant communities, like forest and grassland piece, is an example of an ecotone. In simpler terms, it is a transition area between two different communities where they meet.

Complete step by step answer: Ecotone has a number of the characteristics of every bordering biological community and infrequently contains species not found within the overlapping communities. -Grassland could exist on a broad belt or in an exceedingly little pocket, like a forest clearing, wherever two native communities mix along. The influence of the two bordering communities on one another is understood because of the edge results.
-Associate degree ecotonal space typically contains a higher density of organisms of one species and a larger range of species that are found in either flanking community. Some organisms would like a transformation space for activities like courting, nesting, or forage for food.
-An ecotone is a part that acts as a boundary or a transition between two ecosystems. A typical example can be a part of the fenland between a stream and its bank. Ecotones area unit of nice environmental importance.
-As a result of the world may be a transition between two ecosystems or biomes, it's natural that it contains an outsized style of species of fauna and flora because space is influenced by each of the bordering ecosystems.
Hence option B-a transition between two types of ecosystems particularly soil structure & chemical composition is correct.

Note: Ecotones additionally seem wherever one body of water meets another (e.g., estuaries and lagoons) or at the boundary between the water and also the land (e.g., marshes). Fresh and marine ecotones are characterized by the presence of giant plants that rise from roots attached to the submerged substrate, and thus they occur in areas where lightweight is offered at the lowest of the basin to allow growth.
