(4 marks)How does Barlow (2001) explain the elaborate and apparently non-functional features of some plant species in terms of community ecology? (4 marks)Describe the similarities between predation and parasitism in terms of their impacts on prey/host populations. Could the Lotka-Volterra equations be used to describe parasite and host population interactions? Justify your answer.

How would they impact the structure of your community? (10 marks)
