Question

Ecological races are also known as

• A. Ecards
• B. Ecotone
• C. Ecophens
• D. Ecotypes

Hint:

Ecotypes are a result of long-term adaptation of species to local environmental conditions.

Answer 1

The Correct Option is D

Ecological races, which are genetically distinct populations within a species that are adapted to specific environmental conditions, are known as ecotypes. These variations help the organisms survive better in their particular habitat.

Answer 2

Elimination approach: "Ecards" is not a recognised ecological term. An ecotone is a transition zone between two different ecosystems (e.g., forest meeting grassland), a spatial concept, not a population type. An ecophene refers to a non-heritable phenotypic variation caused directly by the environment, without any underlying genetic change.
What remains is the term for a genetically distinct, locally adapted population within a species, this is precisely what is meant by an ecotype, i.e., an ecological race.
