Multiple choice zoology biodiversity, classification and conservation levels of biodiversity environmental conservation and biodiversity biodiversity on earth and in india

Species diversity increases as one proceeds from

  1. High altitude to low altitude and high latitude to low latitude

  2. Low altitude to high altitude and high latitude to low latitude

  3. Low altitude to high altitude and low latitude to high latitude

  4. High altitude to low altitude and low latitude to high latitude
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • Species diversity increases as one proceeds from high altitude to low altitude and high latitude to low latitude. The temperature and seasonal variability increases with increased altitude and decreased latitude. Hence, this results in higher species diversity in these areas.

Thus, the correct answer is 'High altitude to low altitude and high latitude to low latitude.'

Select an incorrect statement about biodiversity.

  1. Mountain peaks are more diverse than foot hills.

  2. Valley's are more diverse than mountain peaks.

  3. Shade sides are more diverse than sun sides of mountains.

  4. Western ghats are more diverse than eastern ghats.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Valleys, shade side of mountains and western ghats have more trees and water resources where more diverse fauna and flora may be present due to the availability of their life-sustaining resources comparing with the others. Foothills, when compared with the mountain peak, are more diverse because mountain peaks are at higher altitude there is more sunlight, less water or we can say no water and also colder climate when compared to foothills so it will mostly be covered with either snow or there will exist a grassland.


So the correct option is 'A'.

The species diversity of plants on Earth will be

  1. 2.4%

  2. 22%

  3. 8.1%

  4. 85%

  5. 70%
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Species diversity is the number of different species, that are represented in a given community. 

Species diversity consists of two components: species richness and species evenness. Species richness is a simple count of species, whereas species evenness quantifies how equal the abundances of the species are. More than 70% of species recorded are animals and 22% are plant species.

Multiple choice evs - i the environment and us damaging the forests deforestation and afforestation protecting our environment pollution of soil degradation of land

Choose the wrong pair

  1. Salvodora - Desert

  2. Cenchrus - Savanna

  3. Ables - Coniferous forest

  4. Quercus - Broad leaf forest

  5. Tectona - Temperate forest
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Tectona (teak) is a tropical tree genus native to South and Southeast Asia. It does not naturally grow in temperate forests, making this pairing incorrect.

Multiple choice evs - i the environment and us damaging the forests deforestation and afforestation protecting our environment pollution of soil degradation of land

Which of the following prevents afforestation in deserts?

  1. Goat and grazing animals

  2. Local resident

  3. Unfertility of soil

  4. Low rainfall
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Major problem in desert is lack of rainfall. While grazing of animals and local residents can be controlled but without rainfall growth of trees and afforestation is not possible.

Tropical evergreen forest,

In India, Evergreen forests which are also identified as Tropical rain forest can be located in the in States such as Kerala and Karnataka. These forests are discovered in the westward slopes of the western ghats. They can be also discovered in mountain ranges of Jaintia and Khasi. Some of the trees which can be located in Indian Tropical Forests are ebony, bamboos rosewood, and reeds.

Sundarbans of eastern India is an example of___________.

  1. marine Ecosystem

  2. grassland Ecosystem

  3. forest Ecosystem

  4. mangrove Ecosystem
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Mangrove Ecosystem
The name Sundarbans is thought to be derived from sundri or sundari (Heritiera fomes), the name of the large mangrove trees that are most plentiful in the area. The forestland transitions into a low-lying mangrove swamp approaching the coast, which itself consists of sand dunes and mud flats. Mangrove forests constitute about two-fifths of the Sundarbans region’s overall surface area, with water covering roughly half of that area. The landscape is constantly being transformed by the erosional forces of the sea and wind along the coast and by the enormous loads of silt and other sediments that are deposited along the myriad estuaries. Human activity has also altered the landscape, notably through forest removal, which accelerates erosion. In addition, because considerable amounts of river water have been diverted upstream for irrigation and other uses, salinity in the mangrove swamps has moved farther inland, especially in the Indian sector of the territory.

  2. Mangrove forests

  3. Tropical evergreen forests

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

Tropical deciduous forests are characterized by a distinct upper canopy layer. Mangrove and thorny forests have different structural adaptations, and evergreen forests have a much denser, multi-layered canopy structure.
