MIUN Free NEET Quiz Unit 10

1. Populations grow through births and immigration and decline through deaths and emigration.

2. Misra was recognized with Fellowships from the Indian National Science Academy and the World Academy of Arts and Science, as well as the prestigious Sanjay Gandhi Award for Environment and Ecology.

3. dN/dt = rN [(K-N)/K]. In this formula N = Population density at time t.

4. Limited resources lead to competition between individuals.

5. Biodiversity encompasses the entirety of diversity present at all levels of biological organization.

6. How the bulbul singing early morning because the bird’s need to communicate with its mate during breeding season.

7. Recently, 34 ‘biodiversity hotspots’ in the world have been proposed for minimal conservation efforts.

8. Both the species benefit in mutualism, and both lose in competition in their interactions with each other.

9. At any level of biological organisation, the ‘why-type’ questions seek the significance of the process while the ‘how-type’ questions seek the mechanism behind the process.

10. Ecology does not explain anything about populations, communities, or ecosystems.

11. If we do not accept biochemical or molecular criteria for delineating prokaryote species, then their diversity alone might run into millions.

12. The monthly net primary productivity of the whole biosphere is approximately 1700 million tons (wet weight) of organic matter. 

13. Nearly 45,000 species of plants and thrice as many of animals have been recorded from India.

14. Assertions that the introduction of the Nile perch into Lake Victoria led to the extinction of over 200 species of cichlid fish lack conclusive evidence and may overlook other contributing factors to changes in species composition.

15. The annual gross primary productivity of terrestrial is 70% (dry weight).

16. The human liver fluke is a cestode parasite.

17. Predation plays a crucial role in facilitating trophic energy transfer, and certain predators contribute to regulating the populations of their prey.

18. Ecology, as a field of biology, investigates the interactions between living organisms and both the abiotic (physical and chemical) and biotic (other species) components of their environment.

19. Examples of flukes include liver flukes (e.g., Fasciola hepatica) and blood flukes (e.g., Schistosoma spp.).

20. Ramdeo Misra is revered as the Father of Ecology in India.

21. Recently, 34  ‘biodiversity hotspots’ in the world have been proposed for intensive conservation efforts. Of these, three (Western Ghats-Sri Lanka, Himalaya, and Indo-Burma) cover India’s rich biodiversity regions.

22. Ramdeo Misra is not recognised as the father of biotechnology in India.

23. A Community cannot be visualised as a functional unit of nature, where living organisms interact among themselves and also with the surrounding physical environment.

24. The annual gross primary productivity of terrestrial is 55 million tons (dry weight).

25. The genetic variation shown by the medicinal plant Rauwolfia vomitoria growing in different Himalayan ranges is an example of genetic diversity.

26. Another example is the case of a coevolved plant-pollinator mutualism, where extinction of one invariably leads to the extinction of the other.

27. We also have a moral responsibility to take good care of earth’s biodiversity and pass it on in good order to our next generation. 

28. Ex situ conservation methods include neglectful maintenance of threatened species in zoological parks and botanical gardens, in vitro fertilization, tissue culture propagation, and cryopreservation of gametes.

29. Why are night-blooming flowers generally white? because the flower cell do not synthesis any pigments.

30. Majority of the parasites harm the host.

31. The genetic variation shown by the medicinal plant Rauwolfia vomitoria is an example of species diversity.

32. Species diversity tends to be highest in the tropics and diminishes towards the poles.

33. In all communities, many interactive linkages exist, although all are not readily apparent.

34. Parasites might render the host more vulnerable to predation by making it physically weak.

35. Parasites enhance the reproductive success of the host.

36. Parasites boost the hosts’ population density.

37. Similarly, in cases of coevolved plant-pollinator mutualism, the extinction of one inevitably leads to the extinction of the other.

38. The night-blooming flowers typically white? because the flower cell do not synthesis any pigments.

39. The annual gross primary productivity of terrestrial is 115 million tons (dry weight).

40. Nearly 45,000 species of plants and twice as many of animals have been recorded from India.

41. Assertions that the extinction of one species in a coevolved plant-pollinator mutualism inevitably results in the extinction of the other disregard potential ecological responses such as the adaptation of pollinators to alternative plants or the evolution of new mutualistic relationships.

42. Another significant explanation for the high species richness in the tropics is the increased solar energy received, leading to greater productivity.

43. A population is a group of individuals of a given species sharing or competing for similar resources in a defined geographical area.

44. Ecological diversity of Rauwolfia vomitoria could be understood by analysing the concentration and potency of the active reserpine produced.

45. Organisms do not function as organised wholes such as populations, communities, or ecosystems, and the concept of a biosphere is irrelevant.

46. Products of ecosystem processes, known as ecosystem services, do indeed include functions like air and water purification by forests, highlighting the valuable benefits provided by ecosystems to human well-being.

47. Many ecologists regard the entire biosphere as a global ecosystem, as a composite of all local ecosystems on Earth.

48. Ecological effects on populations are not reflected in their size or density and expressing population density in different ways (such as numbers, biomass, or percent cover) has no ecological significance.

49. Ecological interactions between two species are categorized based on their outcomes: competition (both species are negatively affected), predation and parasitism (one benefits while the other suffers), commensalism (one benefits without affecting the other), amensalism (one is harmed without affecting the other), and mutualism (both species benefit).

50. India, home to approximately 45,000 plant species and twice as many animal species, is one of the 12 mega-diverse countries globally.
