An example: There is a population of rabbits. A population of foxes eat these rabbits. The adding number of foxes depends of the adding number of available prey, in this case the rabbits. If there is a decrease in the number of rabbits, there will also be aa decrease in the number of foxes. This all happens because the foxes have to little rabbits to eat to survive. Rabbits are in this case the limiting factor for the growth of the population of foxes.
Shown above: an example of a biotic (physical) limiting factor.
(Biotic (physical) environmental factors in an ecosystem, the organisms of other species can influence the life and the population of a species)
