Here is a sneak peek of the questions included in this test set. Test your preparation by viewing the answer and detailed explanation before starting the timed exam.

Why does the forest floor of a dense, undisturbed natural forest always remain warm and moist to the touch?

ગાઢ, અવ્યવસ્થિત પ્રાકૃતિક જંગલનું જંગલનું માળખું સ્પર્શ માટે હંમેશા ગરમ અને ભેજયુક્ત કેમ રહે છે?

Underground volcanic lava flows under all forestsભૂગર્ભ જ્વાળામુખીનો લાવા તમામ જંગલોની નીચે વહે છે

Continuous respiration and metabolic decomposition of dead organic matter by trillions of decomposers releases thermal energy and moistureલાખો વિઘટનકર્તાઓ દ્વારા મૃત કાર્બનિક પદાર્થોનું સતત શ્વસન અને ચયાપચય વિઘટન થર્મલ ઊર્જા અને ભેજને મુક્ત કરે છે

Tree roots pump boiling mineral water to the surfaceઝાડના મૂળ ઉકળતા ખનિજ જળને સપાટી પર પંપ કરે છે

Forest leaves absorb coldness from the groundજંગલના પાંદડા જમીનમાંથી શીતળતા શોષી લે છે

Correct Answer: Option B

Explanation:

Active microbial decomposition of organic litter is an exothermic metabolic process, keeping the humus layer warm and damp.

કાર્બનિક કચરાનું સક્રિય માઇક્રોબાયલ વિઘટન એ એક્ઝોથર્મિક મેટાબોલિક પ્રક્રિયા છે, જે હ્યુમસ સ્તરને ગરમ અને ભીના રાખે છે.

In a forest\vecosystem, if all herbivores (such as deer and rabbits) were completely exterminated, what would be the immediate domino effect on other trophic levels?

વન ઇકોસિસ્ટમમાં, જો તમામ શાકાહારી પ્રાણીઓ (જેમ કે હરણ અને સસલા) સંપૂર્ણપણે નાશ પામ્યા હોય, તો અન્ય ટ્રોફિક સ્તરો પર તાત્કાલિક ડોમિનો અસર શું હશે?

Carnivores like tigers will instantly start eating grassવાઘ જેવા માંસાહારી તરત જ ઘાસ ખાવાનું શરૂ કરશે

Plants will disappear due to lack of grazingચરવાના અભાવે છોડ અદૃશ્ય થઈ જશે

Herbivores will spontaneously resurrect from humusશાકાહારીઓ હ્યુમસમાંથી સ્વયંભૂ સજીવન થશે

Carnivores (tigers, leopards) will starve due to lack of prey, and plant overgrowth will initially surge followed by\vecosystem collapseમાંસાહારી (વાઘ, ચિત્તો) શિકારના અભાવે ભૂખે મરશે, અને છોડની અતિશય વૃદ્ધિ શરૂઆતમાં વધશે ત્યારબાદ ઇકોસિસ્ટમનું પતન થશે

Correct Answer: Option D

Explanation:

Apex predators depend directly on herbivore prey biomass; losing primary consumers collapses the entire trophic pyramid.

સર્વોચ્ચ શિકારી શાકાહારી શિકારના બાયોમાસ પર સીધો આધાર રાખે છે; પ્રાથમિક ગ્રાહકો ગુમાવવાથી સમગ્ર ટ્રોફિક પિરામિડ તૂટી જાય છે.

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Early practice in middle school builds the mental muscle, speed, and analytical discipline required to ace NTSE, Olympiads, JNVST, Sainik School, and Future Competitive Exams.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन
