What will be the decreasing order of the following biosphere reserves from the point of view of the length?
Gulf of Mannar, Sunderban, Pachmarhi, Kanchenjunga
The question asks us to arrange several Indian biosphere reserves in decreasing order based on their "length." In the context of large geographical areas like biosphere reserves, "length" is best interpreted as their total geographical area or spatial extent. To answer this question accurately, we need to know the approximate areas of the specified biosphere reserves.
Biosphere Reserves Overview
A biosphere reserve is an international designation by UNESCO (United Nations Educational, Scientific and Cultural Organization) for areas that represent unique examples of sustainable development, aiming to reconcile the conservation of biodiversity with its sustainable use by local communities. These reserves are crucial for protecting ecosystems and promoting research, education, and sustainable living. India is home to several such significant biosphere reserves.
Area Analysis of Biosphere Reserves
To determine the decreasing order of these biosphere reserves by their size, let's examine their approximate areas. The "length" mentioned in the question directly corresponds to the total area covered by each reserve. Below is a table showing the approximate area of each biosphere reserve:
| Biosphere Reserve | Approximate Area ($\text{km}^2$) |
|---|---|
| Gulf of Mannar Biosphere Reserve | 10,500 |
| Sunderban Biosphere Reserve | 9,630 |
| Pachmarhi Biosphere Reserve | 4,926.28 |
| Kanchenjunga Biosphere Reserve | 2,619.92 |
Determining Decreasing Order
Based on the approximate areas provided in the table, we can now arrange the biosphere reserves from the largest to the smallest, which represents the decreasing order of their "length" or area:
- Gulf of Mannar Biosphere Reserve: With an area of approximately 10,500 $\text{km}^2$, it is the largest among the listed reserves.
- Sunderban Biosphere Reserve: Covering about 9,630 $\text{km}^2$, it is the second largest, following the Gulf of Mannar.
- Pachmarhi Biosphere Reserve: This reserve has an area of roughly 4,926.28 $\text{km}^2$, placing it third in terms of size among these four.
- Kanchenjunga Biosphere Reserve: With an area of approximately 2,619.92 $\text{km}^2$, it is the smallest among these specific reserves.
Correct Order of Biosphere Reserves
Therefore, the decreasing order of these biosphere reserves based on their area (or "length") is:
- Gulf of Mannar
- Sunderban
- Pachmarhi
- Kanchenjunga
This sequence accurately reflects the spatial extent of each reserve, moving from the largest to the smallest area.
