1. In predation only predator benefits and the interaction is detrimental to the prey.

2. Nile perch — cichlid fish extinction.

3. The malarial parasite needs a vector (mosquito) to spread to reproduce asexually.

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

5. In predation only predator benefits and the interaction is detrimental to the host.

6. Parasites boost the hosts’ population density.

7. Plants have evolved diverse morphological and chemical defences against herbivory.

8. The concept of carrying capacity has no relevance in ecology, and population growth is unrestricted by environmental limitations.

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

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

11. Earth’s rich biodiversity is vital for the very survival of mankind.

12. Products of ecosystem processes  are named as ecosystem services, e.g., purification of air and water by  forests.

13. The cactus have so many thorns? because to protect them from herbivores and dehydration.

14. In minimal communities, very few interactive linkages exist, although all are readily apparent.

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

16. dN/dt = rN [(K-N)/K]. In this formula K = Intrinsic rate of natural increase.

17. Why the bulbul singing early morning because the operation of the voice box and the vibrating bone in the bird.

18. Plants do capture solar energy, initiating the flow of food energy from producers to consumers within ecosystems.

19. When a species becomes extinct, the plant and animal species associated with it in an obligatory way also become extinct.

20. The logistic growth model is considered a more realistic one.

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

22. A population can be visualised as a functional unit of nature, where living organisms interact among themselves and also with the surrounding physical environment.

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

24. The Fungi kingdom boasts more species than all vertebrate species combined.

25. The annual net primary productivity of terrestrial is 115 million tons (wet weight).

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

27. Ecology explains to us about population, community, ecosystem etc.

28. Modern biology is a euphemism for molecular aspects of biology.

29. 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.

30. Both parasitism and predation only one species benefits (parasite and predator, respectively) and the interaction is detrimental to the other species (host and prey, respectively).

31. Lantana — cichlid fish extinction.

32. Earth’s abundant biodiversity is essential for the continued existence of humanity.

33. Eventually, the ‘fittest’ individual will not survive and reproduce.

34. Organisms in an ecosystem indeed occupy specific niches based on their source of nutrition, contributing to the intricate web of interactions within the ecosystem.

35. Species richness is influenced by the area of a region, with the species-area relationship typically following a rectangular hyperbolic function.

36. NPP is not defined as the remaining biomass or energy after producer utilization, as ecosystem processes are far more complex than such simplistic categorizations imply.

37. In our biosphere, immense diversity exists not only at the species level.

38. The annual net primary productivity of terrestrial is 115 million tons (dry weight).

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

40. The causes of high extinction rates at present include habitat (particularly forests) loss and fragmentation, over -exploitation, biological invasions, and co-extinctions.

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

42. Productivity, decomposition, energy flow, and nutrient cycling are not fundamental components of ecosystems but rather abstract concepts with limited applicability.

43. How does the bee know which flower has nectar? because it can sense the electrical charge of flowers that have nectar.

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

45. Biology is presented either as botany, zoology and microbiology or as classical and modern.

46. The annual gross primary productivity of terrestrial is 115 million tons (wet weight).

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

48. Both the species are not benefited in competition.

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

50. As far as many ecologist’s ideas are concerned, the entire biosphere can be considered as a global ecosystem.
