Population growth is a balance between '''Biotic Potential''' and '''Environmental Resistance'''.

'''1. The Two Curves''':
* '''Exponential (The Boom)''': If resources are infinite, a population will double every few years. This cannot last forever.
* '''Logistic (The Balance)''': As resources (food/space) run low, growth slows down and eventually stops at the '''Carrying Capacity'''.

'''2. Limiting Factors''':
* '''The "Bottom-Up" Limit''': There isn't enough food or water.
* '''The "Top-Down" Limit''': There are too many predators or parasites.

'''3. Life History Strategies''':
* '''R-Strategists''': "Quantity over Quality." They have many babies hoping a few will survive. They are good at colonizing new, unstable environments.
* '''K-Strategists''': "Quality over Quantity." They have one baby at a time and protect it. They are good at competing in stable, crowded environments.

'''The Allee Effect''': This is a dangerous phenomenon where a population becomes ''too small'' to survive. If there are only 5 tigers left in a forest, they might not find each other to mate, or they might lose the "group defense" needed to hunt. This leads to an "Extinction Vortex."
