Question 3 of 20
3. Question
2 pointsThe energy flow in an ecosystem is :
1. unidirectional
2. non-cyclic
3. cyclic
4. bidirectional
एक पारिस्थितिकी तंत्र में ऊर्जा प्रवाह है:
1. यूनिडायरेक्शनल
2. गैर-चक्रीय
3. चक्रीय
4. द्विदिश
Correct
Energy flow in an ecosystem is unidirectional and non-cyclic,
whereas nutrient flow is cyclic. The energy enters the plants (from
the sun) through photosynthesis during the making of food.This energy is then passed on from one organism to another in a
food chain.Energy given out by the organisms as heat is lost to the
environment, it does not return to be used by the plants again. This
makes the flow of energy in ecosystem ‘unidirectional’.Incorrect

Question 5 of 20
5. Question
2 pointsThe Montreal Protocol on Substances that Deplete the Ozone Layer aims
to control the production and use of :1. Dichloromethane
2. CFCs
3. HFCs
पदार्थों पर मॉन्ट्रियल प्रोटोकॉल जो ओजोन परत को नष्ट करते हैं, का उद्देश्य उत्पादन और
उपयोग को नियंत्रित करना है:1. डिक्लोरोमेथेन
2. सीएफसी
3. एचएफसी
Select the correct answer using the codes given below.
Correct
Montreal protocol aims to phase out several groups of halogenated
hydrocarbons that have been shown to play a role in ozone depletion.
➔ All of these ozone depleting substances contain either chlorine or
bromine.
➔ These include CFCs and HCFCs. HFCs replaced CFCs and HCFCs.
HFCs pose no harm to the ozone layer because, unlike CFCs and
HCFCs, they do not contain chlorine. The Montreal Protocol
therefore does not address HFCs.
➔ But HFCs cause global warming. Dichloromethane is a new entry
among gases that depletes ozone layer, but at present it has not
been included under Montreal Protocol.Incorrect

3. बेसल सम्मेलन: सीसा
Correct
The Basel Convention is for the Control of Transboundary Movements of
Hazardous Wastes and Their Disposal. It was designed to reduce the
movements of hazardous waste between nations, and specifically to prevent

The Minamata Convention on Mercury is an international treaty designed to
protect human health and the environment from anthropogenic emissions and
releases of mercury and mercury compounds.
Stockholm Convention on Persistent Organic Pollutants is an international
environmental treaty that aims to eliminate or restrict the production and use of
persistent organic pollutants (POPs).Incorrect

Question 20 of 20
20. Question
2 pointsAtmospheric nitrogen can undergo nitrogen fixation by
1. cynabacteria
2. lightning
3. ultraviolet rays
Select the correct answer using the codes given below.
वायुमंडलीय नाइट्रोजन नाइट्रोजन निर्धारण से गुजर सकती है
1. सिनबैक्टीरिया
2. बिजली
3. पराबैंगनी किरणें
Correct
Nitrogen fixation (NF) is a process in which nitrogen
(N2) in the atmosphere is converted into ammonium
(NH4+). Nitrogen fixation occurs naturally in the air
by means of lightning. Biological nitrogen fixation is
carried by cyanobacteria (e.g. the highly significant
Trichodesmium and Cyanothece), green sulfur
bacteria, Azotobacteraceae, rhizobia and Frankia.
NF also takes place in presence of UV rays.Incorrect

combustion can be seen as the brown haze dome above or plume downwind of cities. Nitrogen
dioxide is the chemical compound with the formula NO2. It is one of the several nitrogen oxides.
This reddish-brown toxic gas has a characteristic sharp, biting odour. NO2 is one of the most
prominent air pollutants.

(N2) in the atmosphere is converted into ammonium
(NH4+). Nitrogen fixation occurs naturally in the air
by means of lightning. Biological nitrogen fixation is
carried by cyanobacteria (e.g. the highly significant
Trichodesmium and Cyanothece), green sulfur
bacteria, Azotobacteraceae, rhizobia and Frankia.
NF also takes place in presence of UV rays.
