Question 1
⏱ 0
Consider the following:
1. The biosphere is nearly absent at the extremes of the North and South Poles.
2. The biosphere is most vibrant at the highest mountains and deepest oceans.
Which of the above statements is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Explanation Statement 1 is correct: While the poles support some life, the extreme conditions (such as ice-covered land and extremely low temperatures) limit the types of ecosystems that can exist there. Life is sparse, and thus, the biosphere is considered nearly absent in these areas due to the harsh conditions.
Statement 2 is not correct: While there is life in these regions, "vibrant" suggests an area with a high diversity and abundance of life, and both high mountains and deep oceans are typically more limited in terms of life forms due to factors like extreme cold, low pressure, and nutrient scarcity. While unique species may exist in these areas, they are not considered the most "vibrant" in terms of ecological diversity compared to other ecosystems like tropical rainforests or coral reefs.
