• Population Density: The size of a population compared to the amount of space available.
• Biotic Potential: The potential growth of a population if it could grow in perfect conditions with no limiting factors.
• Carrying Capacity: The largest/maximum number of one species that an environment can support.
• Overpopulation :when the size of a population become larger than the carrying capacity
