  • A
    bottle neck effect
  • Correct answer
    B
    edge effect
  • C
    junction effect
  • D
    Pasteur effect

Solution

The presence of diversity at the junction of terretories of two different habitats is known as edge effect. In other words, the potential for the ecotone to act as habitat for species found in neither major community is called edge effect. In actual, the transition zone between two or more diverse communities is called the ecotone, the population of which becomes more adapted than both the major communities (communities of neighbouring habitats) which are too simple. In addition to this, in this region the density of most of the species is higher than that in the neighbouring.

Hence, the correct answer is option: 'B'.
