Every ecosystem has a limited amount of water…..
Limiting factors LIMIT the size of a population.
Moisture is often a limiting factor forplants. Ex: here, each tree thrives in a different amount of moisture.
Examples: on the size of each other’s populations.
An increase in the zebra population = an increase in the lion population
Conversely, a decrease in the zebrapopulation = a decrease in the lion population
Also an increase in the lions= a decrease inzebras which would cause a decrease in the lions too!
very effective Diseases have always been an effective limiting factor on human populations
The Bubonic plague killed over half of Europe’s population. The fictional “Crippen Virus” in “I amLegend” was over 90% fatal to the human population. Diseases have always been an effective limiting factor on human populations
