• D. Eco-Margin

Answer 1

Answer:

C. Ecotone

• Definition of Ecotone: An Ecotone is a transitional area or zone where two different ecosystems meet and integrate. It acts as a buffer or a biological boundary between two distinct communities (for example, the marshland between a river ecosystem and a dry land ecosystem, or an estuary between fresh water and saltwater).

• Characteristics of an Ecotone:

  • It contains species from both adjacent ecosystems, making it highly diverse.

  • It often supports unique species that are not found in either of the bordering ecosystems.

  • Edge Effect: The tendency for increased variety and density of organisms in the ecotone is known as the "edge effect."
