Pick an option to check yourself, or open the answer below.
Show answer & explanation
Correct answer: B. Plankton, man, fish, grasshopperप्लैंक्टन, मानव, मछली, टिड्डा
Explanation
Options 1, 3 and 4 each form a proper chain (e.g. grass → grasshopper → frog → snake → eagle). In option 2 the grasshopper, a land herbivore of grass, has no link with plankton, fish and man, so this group is not part of one food chain.विकल्प 1, 3 और 4 में उचित खाद्य श्रृंखला बनती है (जैसे घास → टिड्डा → मेंढक → साँप → उकाब)। विकल्प 2 में टिड्डा, जो घास खाने वाला स्थलीय शाकाहारी है, प्लैंक्टन, मछली और मानव की श्रृंखला से नहीं जुड़ता, इसलिए यह समूह एक खाद्य श्रृंखला का घटक नहीं है।More Environmental Studies (EVS) questions
