The correct Answer is:
### Step-by-Step Solution: 1. **Definition of Ecotone**: An ecotone is defined as a transition area between two different ecological communities. It is where two ecosystems meet and integrate. 2. **Characteristics of Ecotones**: Ecotones do not have a clear boundary or demarcation line. Instead, they represent a gradual transition between the adjacent communities. 3. **Composition of Ecotones**: In an ecotone, you can find species from both adjacent communities. This means that the population of organisms in an ecotone includes species from both ecosystems. 4. **Examples of Ecotones**: Common examples of ecotones include the area where a forest meets a grassland or where a river meets a lake. These areas often have unique environmental conditions and biodiversity. 5. **Correct Answer Identification**: Based on the definition and characteristics of an ecotone, the correct choice from the options provided is "a zone of transition between two communities."
