Multiple Select
Which of the following statements about predator and prey relationships is/are correct?
Predator and prey populations cycle in response to each other.
When predator populations decrease, prey populations increase.
Prey populations always remain constant regardless of predator numbers.
Predator populations are not affected by prey availability.

Open Ended
Describe how competition within a population changes as the population approaches its carrying capacity.

46
Hotspot
Choose the area of the graph where you'd expect to find the approximate carrying capacity for this population
47
Labelling
The graph shows changes to a population over time. Four points on the graph are identified by number.
Place a graph position number label in each blank box next to the statement that correctly describes the population change at that point on the graph.
Place only one label in each box.
You do not need to use all the labels.
You may use a label more than once.
