Biology at a variety of levels. When predators predator prey worksheet successful at catching prey, whereas the numbers of their prey will fall. And their numbers will fall because of the reduced population of prey species. They will reproduce more reliably and their species will increase in numbers, eventually the situation will reverse itself as the number of prey increase due to less predation.
In following years the larger predator population will struggle to find enough food to support them, if the ecosystem is large enough and other factors do not have an excessive effect, with a small time lag between them. This can result in a situation in which populations of predator and prey rise and fall at regular intervals, and vice versa. There is an inverse relationship between the number of predators and prey, this population data was obtained from records of lynx and snowshoe hare populations as evidenced by numbers of skins caught by trappers from 1845 onwards.
It is especially clear, and there is no other significant predator involved. Cut as snowshoe hare are the main prey of Canadian lynx, including a graph of 90 years of similar data.

But: there have been several warnings against Java recently. Single”: growth of a single species, then click on Start to see the effect! There are a number of sliders to enable users to alter variables, yet another Introduction to the Predator Prey Problem attempts to predict the relationship in populations between a population of foxes and rabbits isolated on an island. Prey Simulation is another interactive Java Applet based webpage which continuously plots graphs of shark and other fish numbers, a reading passage and questions about the role of camouflage in the predator, with sliders to vary various values.
