With reference to the ecosystem, consider the following statements:1. ...
- In ecology, the term “niche” describes the role an organism plays in a community.
- It is the unique functional role and position of a species in its habitat or ecosystem.
- No two species in a habitat can have the same niche. Hence statement 1 is correct.
- A species’ niche encompasses both the physical and environmental conditions it requires (like temperature or terrain) and the interactions it has with other species (like predation or competition). Ecological niches are found in all types of ecosystems.
- It plays an essential role in the conservation of organisms. If we have to conserve species in their native habitat, we should know the niche requirements of the species.
- Ecocline is a zone of gradual but continuous change from one ecosystem to another when there is no sharp boundary between the two in terms of species composition.
- The ecocline concept was used by vegetation ecologists describing ecological gradients, both spatial continua and time-series, eg. Wetland. Hence statement 2 is correct.
- An ecotype is a population (or subspecies or race) that is adapted to local environmental conditions. Thus, the adaptations of these ecotypes are based on the interactions of their own special sets of genes with their own environment. Hence statement 3 is correct

With reference to the ecosystem, consider the following statements:1. ...
Explanation:
The correct answer is option C, which means that all three statements are correct.
1. No two species in a habitat can have the same ecological niche:
An ecological niche refers to the role and position of a species within its habitat. It includes the physical and biological factors that define how an organism responds to its environment and interacts with other species. Two species cannot occupy the exact same niche because of competition for resources. If two species were to occupy the same niche, there would be intense competition between them, leading to one species outcompeting and displacing the other. This is known as competitive exclusion. Therefore, statement 1 is correct.
2. A wetland is an example of ecocline:
An ecocline refers to a gradual change in the characteristics of a species or a group of organisms along a geographic gradient. It is a continuous variation in phenotypic traits or adaptations in response to changing environmental conditions. On the other hand, a wetland is a distinct type of ecosystem characterized by waterlogged conditions and specific vegetation adapted to such conditions. While a wetland may exhibit some variation in species composition due to changing environmental conditions, it is not an example of ecocline. Therefore, statement 2 is incorrect.
3. An ecotype is a population that is adapted to local environmental conditions:
An ecotype is a population of a species that has genetically adapted to specific environmental conditions within its habitat. These adaptations may include variations in physical traits, behavior, or physiological mechanisms that enhance survival and reproduction in a particular environment. Ecotypes arise due to natural selection and can be found in various habitats, such as deserts, mountains, or aquatic ecosystems. Therefore, statement 3 is correct.
In conclusion, statement 1 and 3 are correct, while statement 2 is incorrect. Hence, the correct answer is option C (1, 2, and 3).
The correct answer is option C, which means that all three statements are correct.
