Question

In the table above, what factors might be contributing to lower wild dog population in Pilanesburg NP?a) Area, prey biomass, average rainfallb) Prey biomass, Prey density/km2c) Average rainfall, area, estimated growth rate, prey density/km2d) Name of the region, area required

Answer 1

If we compare the prey data for each region, we can see total prey biomass is fairly similar; but the growth rate is slightly lower, while the density is far lower in Pilanesburg, which seems to be the main reason why the population of wild dogs there is so low, and also why more area is needed.

This means that prey biomass and density are the main factors that limit the wild dog population in Pilanesburg (B).
