Fill in the blank: Wild dogs need a large area to ______ in order to survive.

• roam

• sleep

• hide

• bark

According to the map, which of the following is NOT one of the areas where wild dogs can be found?

• A) Northern SA

• B) Northeastern SA

• C) Eastern SA

• D) Western SA

What evidence, from the graph shown, suggests that the carrying capacity might be lower in Pilanesburg?

• The line for the Pilanesburg region has the largest slope indicating that a much larger area would be required to support a large wild dog pack compared to the other regions.

• The slope of the lines for Eastern and Northern SA are both the smallest indicating that they require a much larger area to support large wild dog packs.

• The slope of the lines for Pilanesburg is larger than the slope of the line for Northeastern SA indicating that Pilanesburg can support larger wild dog populations than the Northeastern region.

• The slope of the lines for Eastern and Northern SA are both the largest indicating that they do not require a much larger area to support large wild dog packs.

In the table shown, what factors might be contributing to lower wild dog population in Pilanesburg NP? Use what you have learned about the factors affecting carrying capacity in ecosystems to support your answer.

• Area, prey biomass, average rainfall

• Prey biomass, Prey density/km²

• Average rainfall, area, estimated growth rate, prey density/km²

• Name of the region, area required

How might prey density per square kilometer affect the carrying capacity of wild dogs in a given region?

• Higher prey density increases the carrying capacity of wild dogs.

• Higher prey density decreases the carrying capacity of wild dogs.

• Prey density has no effect on the carrying capacity of wild dogs.

• Carrying capacity is only affected by climate, not prey density.

On the basis of your reasoning, in which region would you expect to see the largest number of wild dogs?

How many wild dogs could this area support?

• 24

• 12

• 36

• 6

What evidence best supports your prediction?

• The new area has the same amount of available prey biomass and growth rate as Northeastern SA.

• The new area has similar amounts of available prey biomass to Northeastern SA and rainfall between both Northeastern SA and Northern SA.

• The new area has the same growth rate as Northeastern SA and rainfall between both Northeastern SA and Northern SA.

• The new area has the same growth rate as Northern SA and twice the prey density. So it should be able to support twice the number of wild dogs as Northerns SA.

The scientists collected the data so they could find out what factors were most important in explaining why, in some regions, the wild dogs required more area than others. Sort the data factors into the categories unimportant and important.

Groups:

(a) Unimportant

,

(b) Important

• Tempature

• Prey Density

• Type of Soil

• Prey Biomass

• Growth Rate of Prey

• Annual Rainfall
