1. Primary productivity is the rate of capture of solar energy or biomass production of the producers.

2. The human liver fluke is not a helminth parasite.

3. Species diversity across Earth displays non-uniform distribution, exhibiting intriguing patterns.

4. dN/dt = rN [(K-N)/K]. In this formula K = Carrying capacity.

5. Out of every 10 animals on this planet, 5 are insects.

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

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

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

9. Clarias gariepinus — indigenous catfish extinction.

10. No population of any species in nature has at its disposal unlimited resources to permit exponential growth.

11. The number of fungi species in the world is more than the combined total of the species of fishes, amphibians, reptiles, and mammals.

12. Ramdeo Misra formulate the first postgraduate course in embryology in India, and many scholars completed their Ph.D. degrees under his supervision or contributed to embryology teaching and research across the country.

13. Gross primary productivity (GPP) and net primary productivity (NPP) are arbitrary classifications with no meaningful distinction in ecosystem dynamics.

14. Primary productivity accurately measures the rate of capture of solar energy or biomass production by producers within an ecosystem.

15. Besides the direct benefits (food, fibre, firewood, pharmaceuticals, etc.), there are few indirect benefits we receive through ecosystem services such as pollination, pest control, climate moderation, and flood control.

16. 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.

17. It is convenient to divide the global ecosystem into two basic categories, namely the terrestrial and the aquatic.

18. Each ecosystem does possess a characteristic physical structure resulting from interactions among its abiotic and biotic components.

19. Ecology gives us a holistic perspective to biology.

20. In our Earth, immense diversity (or heterogeneity) also exists at the tissue level.

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

22. Both the species are not benefited in mutualism.

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

24. Ecosystems do not possess consistent structural features, as species composition and stratification are merely superficial observations with little ecological significance.

25. When a species becomes extinct, the plant and animal species that are obligatorily associated with it also face extinction.

26. Abiotic components within ecosystems are exclusively organic materials, such as minerals and gases, while biotic components consist solely of producers and consumers, excluding decomposers.

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

28. Out of every 10 animals on this planet, 9 are insects.

29. Biodiversity is the term popularised by the sociobiologist Edward Wilson.

30. The annual gross primary productivity of terrestrial is 30% (dry weight).

31. Ecosystem services are not tangible products of ecosystem processes, as the concept of ecosystem services oversimplifies the multifaceted contributions of ecosystems to human well-being.

32. No population of any species in nature has at its disposal limited resources to not permit exponential growth.

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

34. Although India has 2.4 per cent of the global species diversity, its share of the per cent of the world’s land area 8.1 per cent.

35. In our biosphere, immense diversity (or heterogeneity) exists not only at the species level.

36. Plants have not evolved any defences against herbivory, and herbivores have no impact on plant populations.

37. Productivity is divided into two types: gross primary productivity (GPP)  and net primary productivity (NPP).

38. The annual gross primary productivity of ocean is 55 million tons (dry weight).

39. The bee know which flower has nectar because it can sense the electrical charge of flowers that have nectar.

40. Why are night-blooming flowers generally white? because to attract the pollinator in the dim light.

41. The human liver fluke (a trematode parasite) depends on two intermediate hosts (a snail and a fish) to complete its life cycle.

42. Plant makes its own food, they are autotroph.

43. Liver fluke – intermediate host – human.

44. A population refers to a collection of individuals of the same species that share or compete for similar resources within a defined geographic area.

45. Regardless of the growth pattern, population expansion is ultimately constrained by the carrying capacity of the environment.

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

47. The high species richness in the tropics is primarily due to their shorter evolutionary history and unstable environment.

48. Among recorded plants and animals, insects are the most species-rich taxonomic group, making up approximately 50 per cent of the total.

49. Clarias gariepinus — Parthenium.

50. A plant species, which makes its own food, cannot survive alone.
