Natural Vegetation and Habitats Questions

Multiple choice natural vegetation and wildlife of india and world resources of india and world general knowledge

Which of the following regions are characterized by little undergrowth, trees of several layers? 

  1. Tropical rain forest

  2. Tropical savanna

  3. Tropical desert

  4. Taiga
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Tropical rainforests are characterized by a highly stratified structure with multiple layers of trees. Because the dense upper canopy blocks most of the sunlight, very little light reaches the forest floor, resulting in sparse undergrowth.

Evergreen forests indicate a climate with ______.

  1. copious rainfall

  2. high temperature

  3. moderate rainfall

  4. year round adequate rainfall
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Evergreen forests thrive in regions where there is no prolonged dry season, meaning rainfall is distributed adequately throughout the year. This continuous water availability allows trees to retain their leaves year-round, unlike deciduous forests which shed leaves during dry periods.

The Savanna is a _______.

  1. forest vegetation of tropical regions

  2. tropical mixed vegetation dominated by grasses

  3. temperate type of grassland having only grasses

  4. type of vegetation adapted to arid climate
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A savanna is a tropical grassland biome characterized by a continuous cover of grasses with scattered, widely spaced trees. It represents a transitional zone between tropical rainforests and deserts.

Which one among the following is a characteristic of evergreen forest?

  1. The trees never shed their leaves

  2. All the trees do not shed their leaves simultaneously

  3. When the trees are leafless, grasses remain green

  4. The name has nothing to do with greenery as such
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Individual trees in an evergreen forest do shed their leaves, but they do not do so all at the same time or in a single season. Consequently, the forest always retains its green canopy throughout the year.

Multiple choice natural vegetation and wildlife of india and world resources of india and world general knowledge

Which of the following is true?

  1. The grasses of tropical grasslands are shorter and less nutritious than those of temperate grasslands

  2. The grasses of temperate grasslands are shorter but more nutritious than those of tropical grasslands

  3. The grasses of tropical grasslands are taller and more nutritious than those of temperate grasslands

  4. The grasses of temperate grasslands are taller and more nutritious than those of tropical grasslands
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Temperate grasslands receive moderate rainfall and have nutrient-rich soils, which support shorter but highly nutritious grasses. In contrast, tropical grasslands (savannas) have a prolonged dry season and nutrient-poor soils, resulting in taller, coarser, and less nutritious grasses.

The dominant Mediterranean scrub vegetation in Southern California is _______.

  1. chaparral

  2. muskeg

  3. fynbos

  4. campos
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Chaparral is the characteristic Mediterranean shrubland biome found in Southern California, consisting of drought-resistant, evergreen shrubs. Fynbos is found in South Africa, muskeg in northern bogs, and campos in South American grasslands.

Multiple choice natural vegetation and wildlife of india and world resources of india and world general knowledge

In which one of the following regions, water availability determines the tree growth and trees exhibit various adaptations to fire?

  1. Tropical rain forest

  2. Tropical savanna

  3. Tropical desert

  4. Taiga
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Tropical savannas experience highly seasonal rainfall, which limits continuous tree canopy growth and creates open grasslands with scattered trees. These trees have developed specialized adaptations, such as thick bark, to survive frequent seasonal wildfires.

Consider the following conditions.
1) Podzol soils.
2) Annual temperature range $ 38 °C$.
3) Annual precipitation about $300$ mm which is fairly uniformly distributed throughout the year.
Which of the following vegetation prevails in above conditions?

  1. Thorn Shrub

  2. Coniferous Forest

  3. Temperature Grassland

  4. Monsoon Forest
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Podzol soils are highly acidic, nutrient-poor soils characteristic of coniferous (taiga) forests. Coniferous forests thrive in high-latitude regions with large annual temperature ranges (up to 38 degrees C) and moderate, uniform precipitation.

Multiple choice natural vegetation and wildlife of india and world resources of india and world general knowledge

Saltbush, with juicy leaves, a good fodder is very common in ______.

  1. Nullarbor Plain

  2. Eastern Highlands

  3. Western Plateau

  4. Great Barrier Reef
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Saltbush is a highly salt-tolerant shrub with juicy leaves that serves as excellent fodder for sheep and cattle. It is widely distributed across the arid and semi-arid regions of Australia, most notably in the Nullarbor Plain.

Multiple choice natural vegetation and wildlife of india and world resources of india and world general knowledge

Identify the wrong statement:
(1) The Western half of Australia is formed of ancient rocks.
(2) Mt. Kosciusko is Australia's highest place.
(3) The most adaptable tree genus in Australia is the Eucalyptus.
(4) Australia is the oldest, lowest, flattest and driest continent in the world.

  1. Only 1

  2. 1 and 4

  3. Only 2

  4. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All four statements are geographically accurate: the Western Plateau consists of ancient shield rocks, Mt. Kosciuszko is the highest peak, Eucalyptus is the most widespread genus, and Australia is widely characterized as the oldest, flattest, and driest inhabited continent. Therefore, none of the statements are wrong.

The luxuriant growth of natural vegetation in Tropical rainforest is due to:
1) fertile soil.
2) hot and wet climate throughout the year.
3) intense sunlight for photosynthesis.
4) seasonal change to facilitate nutrient absorption.
Select the correct answer using the codes given below.

  1. 1 and 4

  2. 2 and 3

  3. 1 , 2 and 3

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Tropical rainforest soils are actually highly leached and nutrient-poor, and these regions experience minimal seasonal variation. The rapid and dense growth of vegetation is primarily driven by the continuous hot and wet climate and abundant sunlight, which maximize photosynthesis and rapid nutrient recycling.
