What is true for ecotone ?
(a) It is a transition zone in between two different species
(b) It is transition zone in between two different population
(c) It is transition zone in between two different communities
(d) Maximum species diversity occurs in ecotone

Options

A. c,d
B. a,d
C. only d
D. only b

Answer

To determine what is true for an ecotone, let's analyze the options provided step by step:

1. **Understanding Ecotone**: An ecotone is a transition area between two different ecological communities. This means it is a region where two distinct ecosystems meet and interact.

2. **Evaluating the Options**:
- **(a) It is a transition zone in between two different species**: This statement is incorrect. An ecotone does not specifically refer to a transition between species; rather, it refers to a transition between communities.
- **(b) It is a transition zone in between two different populations**: This statement is also incorrect. While populations can exist within an ecotone, the term ecotone specifically pertains to communities, not populations.
- **(c) It is a transition zone in between two different communities**: This statement is correct. An ecotone is indeed a transition zone between two different ecological communities, such as a forest and a grassland.
- **(d) Maximum species diversity occurs in ecotone**: This statement is also correct. Ecotones often have higher species diversity due to the overlap of species from both communities and the unique conditions present in the transition zone.

3. **Conclusion**: Based on the analysis, the correct answers are (c) and (d). An ecotone is a transition zone between two different communities and is characterized by maximum species diversity.
