Question

Ecological races are also know as

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

Hint:

The concept of ecotypes was first proposed by Turesson in 1922 to describe genetically based adaptive variation within a species.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Organisms of the same species often exhibit genetic and morphological variations across different habitats. These localized populations are described by specific ecological terms.

Step 2: Detailed Explanation:
- Ecotypes (Ecological races): Genetically distinct geographic varieties or populations within a single species.
These variations are heritable adaptations to local environmental conditions.
- Ecards Ecads (or Ecophenes): Populations of a species that show temporary, non-heritable physical variations in response to a new environment. These changes revert to normal if the organism is returned to its original habitat.
- Ecotone: A transition zone between two distinct ecological communities (such as a forest and a grassland).

Step 3: Final Answer:
Ecological races are also known as ecotypes.
