Question

Often, one change in an ecosystem causes another change. Drag and drop the tiles to show the order in which this group of changes would happen.

Answer 1

2. The Prey Population increases:

As a result of the predator population decreasing in size, the prey will no longer be hunted as much and so their population will rise.

3. The area is overgrazed due to overpopulation.

With so much prey in the system, they will eat up too much of the grass and flora which will lead to overgrazing.

4. The prey population decreases

With the and being overgrazed, the system will no longer be able to support the large number of prey. A lot of them will therefore starve to death which will decrease the pray population.

5.Invasive species dominate the ecosystem.

With less competition for resources from the natural plants in the area which have now been overgrazed, invasive species will dominate the system.
