Natural Vegetation and Habitats Questions

Multiple choice

Rainforests have _______ than deserts.

  1. more dunes

  2. less precipitation

  3. fewer water sources

  4. a greater variety of species
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Rainforests are characterized by high biodiversity compared to the harsh, arid conditions of deserts. Deserts have less precipitation and fewer water sources, making them less hospitable for a wide variety of life.

Multiple choice biology pictorial feature of plant kingdom phanerogams gymnosperms angiosperms

Angiosperms have dominated the land primarily by their ________________.

  1. Power of adaptability to diverse habitat

  2. Nature of pollination

  3. Domestication by humans

  4. Large number of seeds
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Angiosperms dominate the land primarily because of their high adaptability to diverse habitats and efficient reproductive mechanisms. Their ability to colonize various environments is their key evolutionary advantage.

Greatest extent of adaptation to various environments is found in __________.

  1. Gymnosperms

  2. Bryophytes

  3. Ferns

  4. Angiosperms.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Greatest extent of adaptation to various environments is found in angiosperms. Angiosperms grow on most of the places on earth. They grow in hot (Cactus) and cold deserts. They also grow in high altitude of Himalayas, in water (Hydrilla)  and all types of terrestrial habitat.

So, the correct answer is 'Angiosperms.'

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

Some statements are given below: Which of the above statements are true?
Mangrove forests are found in some delta regions in India.
Coniferous forests are found in tropical regions of India.
Date palms are a part of desert vegetation.
Evergreen forests are very dense forests.

  1. A, B and C

  2. A, C and D

  3. B, C and D

  4. A, B and D
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Mangrove forests thrive in deltaic regions like the Sundarbans. Coniferous forests are found in cold, mountainous regions (like the Himalayas), not tropical regions. Date palms are typical desert plants, and evergreen forests are known for their dense canopy. Thus, the first, third, and fourth statements are true.

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

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 code given below 

  1. 1 and 4 only

  2. 2 and 3 only

  3. 1, 2 and 3 only

  4. 1, 2, 3 and 4
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Tropical rainforest soils are actually highly leached and nutrient-poor because heavy rainfall washes away nutrients. There is also no distinct seasonal change in these equatorial regions; instead, the hot and wet climate throughout the year combined with intense sunlight drives the rapid growth of vegetation.

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

Which one of the following regions of India has a combination of Mangrove forests, Evergreen forest and Deciduous forest ?

  1. North Coastal Andhra Pradesh

  2. South -West Bengal

  3. Southern Saurashtra

  4. Andaman and Nicobar Islands
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The Andaman and Nicobar Islands possess a unique geography and climate that supports a diverse range of forest types, including mangrove forests along the coasts, and both tropical evergreen and deciduous forests further inland.

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

A succession taking place in an area where there had been no vegetation earlier is called a _________ succession.

  1. pioneer

  2. primary

  3. secondary

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

Primary succession is the ecological succession that starts in lifeless areas, such as newly exposed rock or sand dunes, where there was no previous vegetation or soil. Secondary succession, on the other hand, occurs in areas where an existing community has been cleared by a disturbance but the soil remains.

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

Xerophytes are __________.

  1. plants that grow in areas of high rainfall

  2. plants which can withstand high degree of salinity

  3. plants which grow in areas of moderate moisture supply

  4. plants which can withstand extreme aridity
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Xerophytes are plants that have evolved specific adaptations, such as thick cuticles, fleshy stems, or deep root systems, to survive in extremely dry environments. These features help them conserve water and withstand prolonged periods of drought.

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

The typical structure of a tropical forest is ______.

  1. single tier

  2. two tier

  3. three tier

  4. four tier
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Tropical forests typically exhibit a multi-layered structure, often simplified in basic ecological classifications as a three-tier system consisting of the canopy, understory, and forest floor. This vertical stratification allows different plant species to adapt to varying levels of sunlight and humidity.
