Q.128 Botany ⭐ 360° Option Elimination Active

NEET 2024 Botany Question 128 Solution

Topic: Biodiversity and Conservation · Official NTA Booklet Code T1

Question

Tropical regions show greatest level of species richness because A. Tropical latitudes have remained relatively undisturbed for millions of years, hence more time was available for species diversification. B. Tropical environments are more seasonal. C. More solar energy is available in tropics. D. Constant environments promote niche specialization. E. Tropical environments are constant and predictable. Choose the correct answer from the options given below:

Option (3) : A, C, D and E only

📚 Biodiversity and Conservation Medium

📋 Given Parameters & Problem Setup

Hypothesis Ecologists and evolutionary biologists explain high species richness in tropics

Candidate Statements A: Prolonged evolutionary time; B: Tropics are more seasonal (False); C: More solar energy; D: Constant environment; E: Niche specialization

The 30-Second Exam Hall Shortcut: ⚡ Tropical Climatic Stability Rule

⏱️ Save ~40 seconds

Tropics are LESS seasonal, relatively more constant and predictable (not more seasonal!). Statement B is false; Statements A, C, D, and E are all true!

1 Examine Statement B: "Tropical environments are more seasonal" -> FALSE! NCERT explicitly emphasizes that tropical environments are LESS seasonal, more constant and predictable compared to temperate regions.

2 Eliminate options containing B:

3 - Option 1 (A, B and C) -> eliminated.

4 - Option 2 (B, C, D and E) -> eliminated.

5 - Option 4 (A, B, D and E) -> eliminated.

6 Only Option (3) A, C, D and E only remains!

7 Instant knockout through single-statement precision!

Why You Can 100% Trust This Shortcut: NCERT Biology · Biodiversity and Conservation (Latitudinal Gradients in Species Diversity)

📐

Step-by-Step Rigorous Workflow & Mathematical Proof

Step 1

Understand Latitudinal Gradient Hypotheses

Evolutionary biologists and ecologists propose three major hypotheses for greater species diversity in tropics: 1. Speciation is generally a function of time. Temperate regions were subjected to frequent glaciations in the past, while tropical latitudes remained relatively undisturbed for millions of years, having prolonged evolutionary time (Statement A). 2. Tropical environments are less seasonal, relatively more constant and predictable (unlike temperate zones). Such constant environments promote niche specialization and lead to greater species diversity (Statements D and E). 3. There is more solar energy available in the tropics, contributing to higher productivity, which indirectly supports greater diversity (Statement C).

Step 2

Detect the Inversion Trap in Statement B

Statement B asserts that "tropics are more seasonal", which directly contradicts ecological reality and NCERT text (tropics are less seasonal).

Step 3

Conclude Option Selection

Statements A, C, D, and E are correct explanations, matching Option (3).

NTA Trap Alert: More vs Less Seasonal Reading Trap

Glancing over "more seasonal" and mentally reading it as "more sunshine/solar".

🛡️ How to avoid the -1 mark: Read climatic statements carefully: Temperate = extreme seasons (glaciations); Tropical = low seasonality (stable climate).

"Tropical environments, unlike temperate ones, are less seasonal, relatively more constant and predictable. Such constant environments promote niche specialisation and lead to a greater species diversity. There is more solar energy available in the tropics, which contributes to higher productivity."
