Which of the following differentiates correctly between Tropical Savannahs and Temperate Grasslands?
  • a)
    Temperate grass is longer but much less nutritious than those of Tropical Savannas.
  • b)
    Temperate grasslands are drier and receive lesser rainfall than savannas.
  • c)
    Temperate Grasslands have scattered trees, unlike in Savannas where the only vegetation is grass and mosses.
  • d)
    Temperate grasslands are found near the coastal regions, whereas Tropical Savannas occur in interior areas in Northern Hemisphere only.
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Which of the following differentiates correctly betweenTropical Savann...
Justification: Option A: Temperate grass here is short and nutritious, not
longer than Savannah. So, A is wrong.
Option B & C: Savannah is Grassland characterized by scattered trees that
are not able to form a canopy. As there is no canopy, the surface gets
sufficient light, and the area supports grasses.
Temperate grasslands are characterized by grasses of different types with
no trees and only a few types of shrubs. The reason of no trees lies in the
fact that temperate grasslands receive lesser rainfall and are drier. So, C is
wrong and B is correct.
Option D: These grow on either side of the equator and extend till the
tropics. This vegetation grows in the areas of moderate to low amount of
rainfall.
Temperate Grasslands are found in the mid-latitudinal zones and in the
interior part of the continents. So, D is wrong.

Which of the following differentiates correctly betweenTropical Savann...
Explanation:

Introduction:
Tropical savannahs and temperate grasslands are two types of grassland ecosystems found in different regions of the world. While both are characterized by the dominance of grasses, there are several key differences between them.

Differentiating Factors:

a) Nutritional Value:
- Temperate grasslands have longer grasses compared to tropical savannahs.
- However, the nutritional value of the grass in temperate grasslands is much lower than that of the grass in tropical savannahs.
- This is because tropical savannahs receive higher rainfall and have more fertile soils, resulting in richer and more nutritious grasses.

b) Rainfall and Moisture:
- Temperate grasslands are drier and receive less rainfall compared to savannahs.
- Temperate grasslands are typically found in regions with a continental climate, where there is less moisture available for plant growth.
- On the other hand, savannahs receive more rainfall, often in the form of seasonal monsoons, which supports the growth of vegetation.

c) Vegetation:
- Temperate grasslands have scattered trees and shrubs interspersed among the grasses.
- These trees are typically smaller and do not form dense forests.
- In contrast, savannahs are characterized by a grassland ecosystem with few or no trees.
- The dominant vegetation in savannahs is grasses and mosses, with scattered shrubs and occasional isolated trees.

d) Geographical Distribution:
- Temperate grasslands can be found in various parts of the world, including North America, Eurasia, and Australia.
- They are often located away from coastal regions and occur in the interior areas of continents.
- Tropical savannahs, on the other hand, are mainly found in the Northern Hemisphere, particularly in Africa, South America, and Australia.
- They occur in both coastal and interior regions, depending on the specific location.

Conclusion:
In conclusion, the correct differentiating factor between tropical savannahs and temperate grasslands is that temperate grasslands are drier and receive less rainfall compared to savannahs. This difference in moisture availability has significant implications for the nutritional value of the grasses and the types of vegetation present in each ecosystem.
