Consider the following statements with reference to 'Ecotones': E...
Ecotones are areas that act as a transition or boundary between two different ecosystems. They are important in maintaining biodiversity and ecological balance. The given statements about ecotones are as follows:
1. Ecotones are the areas that act as a transition or boundary between two ecosystems.
2. They protect ecosystems by acting as buffer zones.
3. They serve as bridges of 'gene flow' between different ecosystems.
Let's analyze each statement:
1. Ecotones are the areas that act as a transition or boundary between two ecosystems:
- Ecotones are transition areas where two different ecosystems meet. These boundaries can be gradual or abrupt, depending on the characteristics of the environments they separate.
- Ecotones are dynamic zones where the characteristics of both ecosystems blend, leading to unique ecological conditions and species compositions.
2. They protect ecosystems by acting as buffer zones:
- Ecotones act as buffer zones that provide protection to ecosystems. They can absorb and filter pollutants, reducing the impacts of human activities on adjacent ecosystems.
- These transition areas can also help mitigate the effects of natural disasters by absorbing excess water or slowing down wind speed, thereby protecting the adjacent ecosystems from flooding or wind damage.
3. They serve as bridges of 'gene flow' between different ecosystems:
- Ecotones facilitate the movement of genes between different ecosystems, allowing for gene flow and genetic diversity.
- This gene flow is crucial for the adaptation and survival of species in changing environmental conditions. It promotes genetic mixing and enhances the resilience of ecosystems.
In conclusion, all three statements about ecotones are correct. Ecotones play a vital role in maintaining ecological balance, protecting ecosystems, and promoting gene flow between different ecosystems. They are dynamic zones that contribute to biodiversity and provide unique habitats for various species.

Consider the following statements with reference to 'Ecotones': E...
- An Ecotone describes an area that acts as a transition or boundary between two ecosystems. This could be, for example, an area of marshland between a river and the riverbank, a clearing within a forest or a much larger area such as the transition between Arctic Tundra and Forest biomes in Northern Siberia.
- As this area is inevitably Influenced by the two bordering ecosystems, it is, therefore, a consequence of this that a higher density of organisms and variety of species can be found within an Ecotone. This increase in biodiversity is referred to as the “edge effect”.
- An Ecotone can be formed naturally – through abiotic factors such as changes in soil composition – but can also be created through the result of human interaction. Clearing of forest areas or irrigation are examples of this.
- Ecotones are considered areas of great environmental importance. As well as providing an area for a large number of species, they often experience an influx from animals looking to nest or searching for food. They may also be considered a habitat of greater genetic diversity and serve as bridges of “gene flow” from one population to another.
- Additionally, an Ecotone can act as a “buffer zone” protecting the neighbouring ecosystem from possible environmental damage – i.e. a wetland area could absorb pollutants preventing them from seeping into a river or estuary. Hence option (d) is the correct answer.
