How several food chains are connected together. Who eats what. All the above 9 / 41In the analysis of man–environment relationship pragmatic possibilism implies that [December 2004] There is no limit for man to exploit the resources of earth. There are limited possibilities to explore the Earth’s resources. The man has to watch and assess the situation and then go ahead with resource utilization. The man has to keep in mind only his basic needs while planning to harness the potential of resourceful earth. 10 / 41Which of the following are included in the biosphere?

Intermixing rapidly with other populations. 15 / 41Which of the following are considered as producers in a food chain?

Different species that can interbreed. Collective members of a species living and interacting across the biosphere. Some organisms that may not belong to any species. 22 / 41Which of the following is not an abiotic condition? Water Soil Temperature Bacteria 23 / 41The existence of atmosphere on the earth is due to The revolution of the earth around the sun. The rotation of the earth. The gravitational force of the earth.

Aurora Codes: A-I, B-II, C-III, D-IV A-II, B-I, C-III, D-IV A-IV, B-II, C-III, D-I None of the above 25 / 41Which of the following is the basis for all food chains? Consumers Producers Decomposers None of the above 26 / 41Total organic matter in an ecosystem is called Biome Biotic community Plants Biomass 27 / 41Energy pyramid is Always inverted Always horizontal Sometimes diagonal None of the above 28 / 41As a result of biomagnification, the secondary consumers will be The most toxic The least toxic Not toxic at all None of the above 29 / 41Which of the following gases is not harmful as a natural component of the atmosphere? Carbon dioxide Hydrogen Nitrogen Water vapours 30 / 41The two main components of an ecosystem are Plants and animals Biotic and abiotic Earth and its surroundings Macro and microorganisms 31 / 41Cloudy nights are warmer compared to clear nights (without clouds) during winters. This is because [December 2005] Clouds radiate heat towards the earth. Clouds prevent cold waves from the sky descending on the earth. Clouds prevent escaping of heat radiation from the earth. Clouds being at great heights from earth absorb heat from the sun and send them towards the earth. 32 / 41The urbanization process accounts for the wind in the urban centres during nights to remain [December 2006] Faster than that in rural areas. Slower than that in rural areas. The same as that in the rural areas. Cooler than that in rural areas. 33 / 41If population growth follows a logistic curve, then the maximum sustainable yield [June 2008] Is equal to half the carrying capacity. Is equal to the carrying capacity. Depends on growth rates. Depends on the initial population. 34 / 41The structure of earth’s system consists of the following. Match the following: [June 2008] List-I List-II (Zone) (Chemical character) A. Atmosphere I. Inert gases B. Biosphere II. Salt, freshwater, snow and ice C. Hydrosphere III. Organic substances D. Lithosphere IV. Light silicates Codes: A-II, B-III, C-I, D-IV A-I, B-III, C-II, D-IV A-II, B-I, C-III, D-IV A-IV, B-II, C-III, D-I 35 / 41Earth is often struck by solar eruptions, which comprise energetic particles that are hurled away from the Sun into space. Which of the following statements reflect the effect on earth? 1. When these eruptions interact with the magnetic field, they cause beautiful auroras. 2. They break down radio communication and power supplies. 3. They don’t affect life support system on earth. Codes: 1 only 1 and 2 only 2 and 3 only 3 only 36 / 41A temperature inversion is a condition when the air Near the ground is lighter. Near the ground is cooler than air at the higher altitudes. Near the ground is hotter than that at higher altitudes. None of the above 37 / 41Beginning from the surface of earth, what is the sequence of different layers of atmosphere?

Stratosphere Mesosphere Troposphere None of the above 40 / 41In which of the following atmospheric layers ionosphere occurs? Mesosphere Exosphere Stratosphere Troposphere 41 / 41In an ecotone, the species which become abundant are called Keystone species Endemic species Edge species Foster species Your score isThe average score is 41% LinkedIn Facebook VKontakte 0% Restart quiz People, Development and Environment MCQShare this: Share on X (Opens in new window) X Share on Facebook (Opens in new window) Facebook Email a link to a friend (Opens in new window) Email Share on WhatsApp (Opens in new window) WhatsApp Share on Telegram (Opens in new window) Telegram Share on Pocket (Opens in new window) Pocket Share on Tumblr (Opens in new window) Tumblr Pages 1 2 3 4 5
