Artificial ecosystems are Cropland ecosystem Aquaculture ponds Aquarium All 2. As per the second law of thermodynamics the energy degraded is in the form of unavailable heat energy and constitute Entropy Standing crop Biomass Pyramid 3. Identity the correct one from the following as we move up from lower trophic level to the higher ; level in ecological pyramids Number increases in predatory food chain Number increases in parasitic food chain energy increases in predatory food chain Biomass decreases is aquatic food chain 4. In a food chain the largest population is that of Primary Consumers Secondary consumers Decomposers Producers 5. The rate of formation of new organic matter by consumer Net productivity Net primary productivity Secondary productivity Gross primary productivity 6. Biomes are Aquatic vegetation Major ecological grouping of animals and plants Major ecological grouping of plants Indicators of climate of a place 7. The occupational address of a species is often called its Biome Niche Environment Habitat 8. Eutrophic lakes means Lake rich in nutrients Lake poor in nutrients Lake poor in flora and fauna Lake lacking water 9. The energy available at the primary Consumer level is Greater than that of primary trophic level Lesser than that of primary carnivore level Greater than that of secondary carnivore level Lesser than that of secondary carnivore level 10. If the energy in the body mass of secondary carnivores is O.lkJ, the NPP of producers of that i ecosystem is 10,000 kJ l,000kJ l00kJ KJ 11. Decomposition of organic nitrogen of dead organisms into ammonia is denitrification nitrification ammonification combustion 12. The sum total of all the biotic and abiotic factors that surround and potentially influence an organism constitutes Biome Ecosphere Environment for the organism Biological community 13. Who had proposed the term Ecosystem ? Calvin Odum Tansley Gardner 14. Abiotic component in an ecosystem is Bacteria Chlamydomones Water Chlorella 15. Ecosystem is a self sufficient, self maintaining dynamic system in which there is a Communities and abiotic components function together Non-cyclic, unidirectional flow of the energy Cyclic exchange of nutrients All of the above 16. An ecosystem resist change because it is in a state of Deficiency of light Shortage of components Homeostasis Imbalance 17. AH ecosystems have no boundaries because They require minerals for their functioning They cannot occur in isolation They are large in size They require light from all sources 18. Biologist celebrate (observe) 5th June as…… World population day World environment day World hygiene day Malaria day 19. Biotic components include Only consumers Only producers Only produces and consumers Produces, consumers and decomposers 20. The two major functional components of an ecosystem are Food chain and decomposers Energy flow and food chain Mineral cycling and energy flow Energy flow and decomposes Loading … Related posts: NEET Foundation-Zoology-Ecology and Environment Test-3 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.
