Question

The type of ecosystem in Coringa region is

• A. Grass lands
• B. Mangrove
• C. Desert
• D. Mountain

Hint:

Coringa Wildlife Sanctuary (Kakinada, Andhra Pradesh) = India's second-largest mangrove forest. The largest mangrove forest in India is Sundarbans (West Bengal/Bangladesh), which is also a UNESCO World Heritage Site and home to the Royal Bengal Tiger. Mangroves are characterised by salt-tolerant trees in intertidal coastal zones with specialized root systems.

Answer 1

The Correct Option is B

Concept:
An ecosystem is a community of living organisms interacting with each other and their non-living environment. Ecosystems are classified based on their geographical features and dominant vegetation. The Coringa region is a specific, well-known geographical location in India with a distinctive ecosystem type.

Step 1: What and where is the Coringa region?
The

Coringa Wildlife Sanctuary is located in the

Godavari delta, near

Kakinada in

East Godavari district, Andhra Pradesh, India. It sits at the confluence of the Godavari river and the Bay of Bengal.

Step 2: What type of ecosystem is Coringa?
Coringa harbors the

second-largest mangrove forest in India (after the Sundarbans in West Bengal). The ecosystem at Coringa is a

mangrove ecosystem (also called mangrove forest or tidal wetland ecosystem). Characteristics of the Coringa mangrove ecosystem:

• Located in intertidal zones (where land meets sea/estuaries).

• Dominated by salt-tolerant (halophytic) mangrove trees like Avicennia marina, Rhizophora, Bruguiera etc.

• The trees have special root adaptations: prop roots, pneumatophores (breathing roots that project above the mud).

• Rich biodiversity: home to saltwater crocodiles, otters, fishing cats, migratory birds, and a rich marine life.

• Acts as a coastal shield against cyclones and storm surges.

• Important nursery for fish and marine species.

Step 3: Why other options are wrong.

• (A) Grass lands: Grassland ecosystems are found in interior regions with moderate rainfall and seasonal climates (e.g., Deccan plateau grasslands). Coringa is coastal/deltaic.

• (C) Desert: Desert ecosystems are characterised by very low rainfall and sparse vegetation (e.g., Thar Desert in Rajasthan). Coringa receives adequate rainfall being coastal.

• (D) Mountain: Mountain ecosystems are at high altitudes (e.g., Eastern Ghats, Himalayas). Coringa is at sea level in a river delta.
