The correct path of energy flow in an ecosystem is Herbivores —> carnivores —> producers —> decomposers Herbivores —> producers —» carnivores —> decomposers Producers —» herbivores —» decomposers Producers —> herbivores —> carnivores —> decomposers 2. About how much of chemical energy of producer tissues becomes chemical energy of a herbivores tissues 50% 10% 30% 1% 3. The trophic level of lion in a forest ecosystem is T3 T4 T2 T1 4. What percentage of incident solar radiation is captured in photosynthesis by plants? 0.8-4% . 0.2-1% 1-5% 50% 5. Mark the odd one (with respect to second trophic level) Wolf Grasshopper Cow Zooplanktons 6. Which of the following statement about GFC is incorrect? Sun is the source of energy Begins with consumers Major conduit for energy flow in aquaticeco systems Size of organisms commonly increases at higher trophic levels 7. Amount of biogenetic nutrients present in the abiotic environment per unit area at any time is called Standing state Standing crop NPP Nutrients immobilization 8. Find an incorrect statement for DFC Starts with solar energy Terminates in GFC 2) Requires specific detritivores Plays major role in terrestrial sytems 9. A food web decreases Decreases variety of food at each trophic level Delicately balances the inter relations amongst organisms Decreases variety of food but increases quantity of food at each trophic level Increases variety as well as quantity of food at each trophic level 10. Energy requirement for maintenance of body with successively higher trophic level Decreases Increases Remain same Always 10% 11. Rate of organic matter stored by producers in their bodies per unit time and area is called as GPP NPP Secondary productivity Ecological efficiency 12. Of the incident solar radiation, percent of the photosy nthetically active radiation (PAR) is 750 < 50 100 0 13. Of the PAR the percent captured by plants is more than 50 100 only 2-10 zero 14. The beginning of the DFC is by seed germination by fertilization by the death of the organisms all the above 15. In a terrestrial ecosystem, a much larger fraction of energy flows through Grazing food chain Detritus food chain Both (1) and (2) None 16. A certain mass of living material at a particular time in each trophic level is called Standing state Stratification Standing crop Species composition 17. The pyramid of biomass in a sea Upright Inverted Spindle None 18. Ecological pyramids does not accommodate Food chain Trophic levels Food web None 19. The amount of nutrients present in the soil at any given time is called Ecological succession Primary succession Standing state Standing crop 20. The natural reservior of phosphorus is Humus Litter Rock Detritus Loading … Related posts: NEET Foundation-Zoology-Ecology and Environment Test-5 NEET Foundation-Zoology-Ecology and Environment Test-8 NEET Foundation-Zoology-Ecology and Environment Test-9 NEET Foundation-Zoology-Ecology and Environment Test-11 NEET Foundation-Zoology-Ecology and Environment Test-10 Powered by YARPP.
