Look at the graph. It shows a typical variation of populations of predators (wolves, tigers etc.) and prey (deer, rabbits etc.) in a habitat such as a forest.
Answer these questions.
1. Why is the predator population always lower than the prey population?
2. Point A is the rainy season. Why is the prey population increasing?
3. Why does the predator population starts increasing after the increase in the prey population?
4. As the predator population increases, why does the prey population starts declining (point B)?
5. Why does the predator population now start to decrease (point C)?
6. Will the graph maintain the same shape if a calamity such as disease struck the prey and they died in large numbers? What do you expect will happen?
