A Correct answer
Explanation

Traveling from Mangalore on the wet west coast to Chennai on the drier east coast, one transitions through different rainfall zones. The vegetation changes from Tropical Evergreen on the coast, to Tropical Wet Deciduous on the slopes, to Tropical Semi-Evergreen, and finally to Tropical Dry forests in the rain-shadow region of the Deccan Plateau and the east coast.

Open stunted forests with bushes and small trees having long roots and sharp thorns or spines are commonly found in _________.

  1. Eastern Odisha

  2. North-Eastern Tamil Nadu

  3. Shiwalik and Terai region

  4. Western Andhra Pradesh

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The description of stunted trees, long roots, and sharp thorns is characteristic of tropical thorn forests and scrub vegetation, which adapt to semi-arid climates with low rainfall. Western Andhra Pradesh (Rayalaseema region) lies in the rain shadow of the Western Ghats and receives very little rainfall, making it a prime location for this type of vegetation.

In the grassland, trees do not replace the grasses as a part of an ecological succession because of ____________.

  1. insects and fungi

  2. limited sunlight and paucity nutrients

  3. water limits and fire

  4. none of the above

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Grasslands are characterized by seasonal rainfall and periodic fires. Water scarcity during dry seasons and frequent fires prevent trees from establishing and dominating, keeping the ecosystem dominated by grasses.

  1. a desert region

  2. a mountainous region

  3. a humid region

  4. a very cold region

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Which of the following is most stable ecosystem?

  1. Forest

  2. Grassland

  3. Desert

  4. Sea

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The ocean (sea) is considered the most stable ecosystem on Earth. Its massive volume, high chemical buffering capacity, and relatively constant temperature and salinity over long geological periods make it highly resistant to sudden ecological changes.
