Question

The transitional zone between two ecosystems is known as

• A. Ecocline
• B. Ecotone
• C. Biome
• D. Savannah

Hint:

Ecotone = Transition. (Think of Tone as a shift). The "Edge Effect" makes ecotones a favorite spot for birdwatchers and wildlife photographers because of the high species mix!

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The question asks for the ecological term describing the boundary or transition area where two different communities or ecosystems meet and integrate.

Step 2: Detailed Explanation:

• Ecotone: This is the correct term. It is a zone of junction or a transition area between two diverse ecosystems (e.g., the area between a forest and a grassland, or an estuary which is the ecotone between a river and the sea).

• Characteristics of Ecotones:
- They are often very narrow, but can be quite wide.
- They are zones of high environmental tension and stress.
- Edge Effect: Ecotones usually contain species from both adjacent communities as well as species unique to the ecotone itself. This often results in higher biodiversity and population density compared to the neighboring ecosystems.

• Evaluating other options:
- Ecocline (A): A gradual continuous change in species composition along an environmental gradient (like altitude or moisture), rather than a specific boundary zone.
- Biome (C): A large geographical area characterized by a specific climate and vegetation type (e.g., Tropical Rainforest).
- Savannah (D): A specific ecosystem type (grassland with scattered trees), not a transitional term.

Step 3: Final Answer:
The transitional zone is defined as an Ecotone.
