Real questions that test this

खालील पैकी कोणता घटक प्रवाल किटकांच्या वाढीला कारणीभूत आहे? Which of the following factor is responsible for low coral growth?

1)सागर जलाचे अधोवहन / Downwelling of sea water
2)सागर जलाचे उर्ध्ववहन / Upwelling of sea water✓ Correct
3)सागर जलाचे तळप्रवाह / Under current of sea water
4)औष्णिकक्षारतामूलक प्रवाह / Thermohaline current

Upwelling brings cold, nutrient-rich deep water to the surface, which lowers temperatures and introduces excess nutrients/turbidity that hinder coral growth.

परपोषी जीवामधील, मुख्यतः सूक्ष्मजीव व बुरशी मृत पेशीद्रव्यातील क्लिष्ट संयुगे फोडून त्याचे सोप्या घटकात रूपांतर करतात जे इतर जीवांना उपयुक्त ठरतात त्या परपोषीजीवांना ________ म्हणतात. / Heterotrophic organisms, chiefly bacteria and fungi that breakdown the complex compounds of dead protoplasm and release simple usable substances for other organisms are :

1)स्वयंपोषी / Autotrophs
2)विघटक / Decomposers✓ Correct
3)भक्षक / Consumers
4)मीश्रहारी / Omnivorous

Heterotrophic organisms like bacteria and fungi that break down dead organic matter into simpler substances are known as decomposers or saprophytes.
