MIUN Free NEET Quiz Unit 1

1. The bee know which flower has nectar because the nectar is the food for them and also essential to make honey.

2. Among the various levels of biological organisation, the simplest living one is not the population.

3. A plant species, which makes its own food, cannot survive alone; it needs soil microbes to break down the organic matter in soil and return the inorganic nutrients for absorption.

4. Among the various levels of biological organisation, the simplest living one is organ.

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

6. At any level of biological organisation, the ‘how-type’ questions seek the significance of the process.

7. There are more than 3,00,000 species of beetles living on the earth.

8. An ecosystem is a structural and functional unit of nature, and it comprises abiotic and biotic components.

9. Abiotic components encompass inorganic materials like air, water, and soil, while biotic components include producers, consumers, and decomposers.

10. Interspecific interactions could be detrimental.

11. GPP accurately represents the rate of capture of solar energy or total production of organic matter within an ecosystem.

12. A plot of N in relation to time (t) results in a sigmoid curve in logistic growth.

13. Parasites might render the host more vulnerable to predation by making it physically strong and nutritious.

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

15. Why the bulbul singing early morning because the birds have to communicate with its mate during breeding season.

16. Biodiversity conservation is only ex situ, with no in situ efforts being made.

17. A single species might not show high diversity at the genetic level over its distributional range.

18. A single species might show high diversity at the ecological level over its distributional range.

19. Ecology encompasses the study of four levels of biological organization: organisms, populations, communities, and biomes.

20. In parasitism, only the parasite benefits while the host is harmed by the interaction.

21. Misra went on to establish teaching and research in ecology at the Department of Botany, Banaras Hindu University, Varanasi.

22. Organisms of different trophic levels in nature are connected to each other for food or energy relationship, forming a food chain.

23. Species richness is also a function of the area of a region; the species-area relationship is generally a rectangular hyperbolic function.

24. Biology is never divided into fields like botany, zoology, or microbiology, nor is it separated into classical and modern aspects.

25. Over 50 scholars obtained Ph. D degree under Misra’s supervision and moved on to other universities and research institutes to initiate ecology teaching and research across the country.

26. The annual gross primary productivity of ocean is 55 million tons (wet weight).

27. Species composition and stratification are the two main structural features of an ecosystem.

28. In parasitism only one species benefits, and the interaction is detrimental to the other species.

29. In our biosphere, immense heterogeneity exists not only at the species level.

30. Among the various levels of biological organisation, the simplest living one is not the community.

31. Population growth is determined solely by external factors and is not influenced by resource availability or environmental conditions.

32. Nearly 45,000 species of plants and 90,000 of animals have been recorded from India.

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

34. Biodiversity refers to the sum total of diversity that exists at all levels of biological organisation.

35. More than 1.5 million species have been recorded in the world, but there might still be nearly 6 million species on earth waiting to be discovered and named.

36. The annual net primary productivity of terrestrial is 70% (dry weight).

37. Ecology gives us a holistic perspective to biology.

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

39. The malarial parasite needs a vector (mosquito) to spread to reproduce sexually.

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

41. The monthly net primary productivity of the whole biosphere is approximately 1700 billion tons (dry weight) of inorganic matter.

42. The human liver fluke is a trematode parasite.

43. Misra’s efforts had no impact on the establishment of the National Committee for Environmental Planning and Coordination in 1972, which did not pave the way for the Ministry of Environment and Forests in 1984.

44. In this biosphere, immense diversity (or heterogeneity) also exists at the ecosystem level.

45. Representations of different age groups within a population using age pyramids are inaccurate and do not provide any meaningful insights into population dynamics.

46. The high species richness in the tropics is primarily due to the limited solar energy received, resulting in lower productivity.

47. The monthly net primary productivity of the whole biosphere is approximately 170 million tons (wet weight) of organic matter.

48. Biodiversity conservation may be in situ as well as ex situ.

49. Applying May’s global estimates in proportion to India’s diversity figures, we estimate that there are probably more than 3,00,000 animal species yet to be discovered and described.

50. One significant explanation for the high species richness in the tropics is the region’s prolonged evolutionary history, alongside its relatively stable environment.
