Question

'Edge effect' is observed in case of

• A. Ecozone
• B. Ecosphere
• C. Ecotone
• D. Biotope

Answer 1

Answer: (C)

The two vegetation of ecosystem is separated by ecotone. Ecotone is a transitional zone by which two biomes are separated. For example, forest and grassland. It is where two communities integrate. It has some characteristics of both communities. It is a mixture of species of both communities. It may be local (the zone between a field and forest) or regional (the transition between forest and grassland ecosystems). It may be narrow or wide. Edge effects refer to the changes in population or community structures, that occur at the boundary of two habitats.As the edge effects increase, the boundary habitat allows for greater biodiversity.

Thus, the correct answer is option B.
