Suppose a bacterial infection kills off most of the prey at point B on the graph. How would this affect the predator and prey growth curves on this computer model at point C? At point D?

it would affect the growth curves because you see if a bacteria affects predators (that hunt and eat preys) the number of predators would decrease as they would be killed by the infection
Less predators means more preys as they aren’t hunted down as much so they growth curve for preys would be positive while for predators it would be negative

The predator growth curve at point C and D will be ; Negative ( decreases )
The prey growth curve at point C and D will be ; Positive ( Increases )

If an infection kills most of the prey at a point ( B ) before the predators can get to the preys at point ( c ). The number of predators between points B and C will reduce due to the unavailability of prey to feed on.

Therefore at points C and D the amount of available predator will decrease while the number of available prey will gradually increase because of the scarcity of predators which would have negatively contributed to their growth just like the bacterial infection.

Hence we can conclude that The predator growth curve at point C and D will be ; Negative ( decreases ) while The prey growth curve at point C and D will be ; Positive ( Increases ).
