A : tropics have more biodiversity.
R : Climate of tropical region is more seasonal.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation od the assertion, then mark(1)
B. If both Assertion & Reason are true but the reason is not the correct expanation of the assertion, then mark (2)
C. If Assertion is true statements but Reason is false, then mark (3)
D. If both Assertion and Reason are false statements, then mark(4).

Answer

To analyze the assertion and reason provided in the question, we can break down the solution into clear steps:

### Step 1: Understand the Assertion
The assertion states that "tropics have more biodiversity." This means that tropical regions have a higher number of different species (species richness) compared to other regions.

### Step 2: Evaluate the Reason
The reason given is that "the climate of the tropical region is more seasonal." This implies that there are significant seasonal changes in the climate of tropical regions.

### Step 3: Analyze the Truth of the Assertion
Research and ecological studies indicate that tropical regions indeed have more biodiversity. This is due to several factors such as:
- Higher solar energy availability.
- A more stable and constant environment.
- Less seasonal variation compared to temperate regions.
- Historical factors like the lack of glaciation during ice ages, allowing species to thrive.

### Step 4: Analyze the Truth of the Reason
The reason states that the climate of the tropical region is more seasonal. However, this is incorrect. Tropical regions typically experience less seasonal variation in climate, which contributes to their high biodiversity. The climate is generally warm and humid throughout the year, leading to a stable environment for various species.

### Step 5: Conclusion
Based on the analysis:
- The assertion (A) is true: Tropics have more biodiversity.
- The reason (R) is false: The climate of tropical regions is not more seasonal; it is less seasonal.

Thus, the correct answer is that the assertion is true and the reason is false.

### Final Answer
Assertion (A) is true, and Reason (R) is false.
