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 ecotones, let's analyze the options step by step:

1. **Understanding Ecotone**: An ecotone is a transition area between two different ecological communities. It is characterized by a mix of species from both communities and often has its own unique species.

2. **Evaluating the Options**:
- **(a) It is a transition zone in between two different species**: This option is incorrect. Ecotones involve communities, not just individual species.
- **(b) It is a transition zone in between two different populations**: This option is also incorrect. While populations can exist within an ecotone, the term refers to communities rather than populations.
- **(c) It is a transition zone in between two different communities**: This option is correct. An ecotone is indeed a transition area between two distinct ecological communities.
- **(d) Maximum species diversity occurs in ecotone**: While ecotones can have high species diversity, this statement is not universally true for all ecotones.

3. **Conclusion**: The correct answer is **(c) It is a transition zone in between two different communities**.
