Question:
Given below are two statements.
Statement I: There is less species biodiversity in tropical latitudes than in temperate region
Statement II: Tropical environments unlike temperate ones are less seasonal, relatively more constant and predictable.
In the light of the above statements, choose the correct answer from the options given below.

Statement II: Tropical environments unlike temperate ones are less seasonal, relatively more constant and predictable.
In the light of the above statements, choose the correct answer from the options given below.
Show Hint
Tropics = High Biodiversity. Why? Because they have more solar energy, longer evolutionary time (undisturbed), and constant/predictable seasonal environments.

- Both Statement I and Statement II are true
- Both Statement I and Statement II are false
- Statement I is true, but Statement II is false
- Statement I is false, but Statement II is true
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept: The latitudinal gradient of biodiversity describes the pattern where species richness generally increases as one moves from the poles towards the equator.
Step 2: Key Formula or Approach: Evaluate each statement against established ecological principles regarding global biodiversity distribution and climate stability.
Step 3: Detailed Explanation: Statement I asserts that there is less species biodiversity in tropical latitudes compared to temperate regions.
This is fundamentally false. The tropics actually harbor the highest levels of biodiversity on Earth, far exceeding temperate regions.
Statement II states that tropical environments are less seasonal, relatively more constant, and predictable.
This is a true ecological fact. Unlike temperate regions which suffer from severe glaciations and drastic seasonal changes, tropical latitudes have remained relatively undisturbed for millions of years. This constant and predictable environment promotes niche specialization and leads to higher species richness.
Therefore, Statement I is false, and Statement II is completely true.
Step 4: Final Answer: The correct option is (4).
