In a food chain herbivores are Primary consumers Decomposers Primary producers Secondary consumers 2. The sequence for species through which the organic molecules in community pass is called a Food web Food chain Nutrient cycle Pyramid of energy 3. A group of interconnected food chains is called a Pyramid of energy Food web Food cycle Complex food chair 4. With regard to ecological food chain man is a Both producer and consumer Producer only Consumer Consumer and decomposer 5. In a grazing food chain the largest poulation is that of Primary consumers Secondary consumers Decomposers Producers 6. The organisms at the base of food chain are Herbivores Photosynthetic plants Saprophytic plants Carnivores 7. In detritus food chain, primary consumer is Insect, larva, nematodes Herbivores Bacteria and fungi All of these 8. A detritus food chain in comparison to grazing food chain is Equal Broader Longer Shorter 9. A ecological pyramid, devised by C. Elton 1927; is a graphic diagram that shows relations! between Transfer of food through food chains Organisms and environment Various trophic levels of a food chain Populations and communities within an ecosystem 10. The transfer of energy from organism to organism in a natural community establishes Natural barriers Biological control Food chains All the above 11. We refer to the following as the food chain Large number of human beings forming a human chain near a source of food Large number of animals near a source of food Transfer of food energy from the green plants through a series consumed by organism None of these 12. The better idea of the productivity of an ecosystem Pyramid of energy Pyramid of biomass Pyramid of numbers All of the above 13. The amount of living matter present in an ecosystem at a given time is called Productivity Recycling state Standing crop Biomass 14. Which ecological pyramid can never occur in an inverted form ? Pyramid of species richness Pyramid of numbers 2) Pyramid of biomass Pyramid of energy 15. Pyramid of numbers in a grassland ecosystem is always inverted always upright both (1) and (2) spindle-shaped 16. The relationship in an ecosystem can be depicted by pyramid of energy pyramid of biomass pyramid of numbers all of the above 17. Pyramid of numbers deals with number of species in an area individuals in a community individuals in a trophic-level subspecies in a community 18. An ecological pyramid of biomass is often an inverted pyramid in which of following ecosystem Tundra Desert Ocean Rain forest 19. In forest ecosystem pyramid of numbers is Upright Inverted Spindle form None of above 20.
