Mr X is eating aurd/yoghurt. For this food intake in a food chain he should be considered as occupying First trophic level Second trophic level Third trophic level Fourth trophic level 2. Assertion (A): In a food chain members of successive higher leels are fewer in number Reason (R) : Number of organisms at any trophic level depends upon the availability of organisms which serve as food at the lower level. Both (A) & (R) are true and the reason is the correct explanation of the (A) Both (A) & Reason are true but the reason is not the correct explanation of the (A) If (A) is true but (R) is false Both (A) and (R) are false 3. Assertion (A): Living organisms are regarded as closed systems Reason (R) : Energy of living organisms cannot be lost or gained from the environment Both (A) & (R) are true and the reason is the correct explanation of the (A) Both (A) & Reason are true but the reason is not the correct explanation of the (A) If (A) is true but (R) is false Both (A) and (R) are false 4. The flora and fauna in lakes or ponds are Lentic biota Lotic biota Abiotic biota Field layer 5. The relationship in an ecosystem can be depicted in pyramid of energy pyramid of biomass ovramid of numbers all of these 6. Pyramid of energy in a river ecosystem is Always upright Always erect Constant Declining 7. Food chain is a series of population which starts with producers. It is concerned with Biotic components only Energy flow and transfer of nutrients Both (1) and (4) Biotic and decomposers 8. Pyramid of energy in a pond ecosystem, is always inverted linear irregular upright only 9. Broad leaved forest are found in Tropical deciduous forest Mediterranean ever green forest Temperate deciduous forest North coniferous forest 10. In a food chain the total amount of living material is depicted by Pyramid of energy Pyramid of number Pyramid of biomass All of the above 11. Ten percent law of energy transfer in a food chain is given by Schimper Elton Haeckel Lindeman 12. Benthic organisms are found in surface of marine water middle of water in sea bottom of sea on ground 13. A lake with nutrients is called trophic euphotic oligotrophic eutrophic 14. Biotic factors are chemical factors of soil which afffect life physical factors of soil which affect life all living organisms which influence otherorganisms factors of atmosphere which affect life 15. If decomposers are removed what will happen to the ecosystem ? Energy cycle is stopped Mineral cycle is stopped Consumers cannot absorb solar energy Rate of decompostion of mineral increases 16. Study of relationship between communities and environments is called Ethynology Ecology Synecology Autecology 17. Largest ecosystem of the world are forests desert great lakes grasslands Loading … Related posts: NEET Foundation-Zoology-Ecology and Environment Test-3 NEET Foundation-Zoology-Ecology and Environment Test-7 NEET Foundation-Zoology-Ecology and Environment Test-8 NEET Foundation-Zoology-Ecology and Environment Test-9 NEET Foundation-Zoology-Ecology and Environment Test-10 Powered by YARPP.
