LIMITING FACTORS THAT CONTROL THE PROCESS OF POPULATION GROWTH

NUTRIENTS LARGER THE POP. GROWTH, FOOD BECOMES LIMITED LEADS TO TRANSITIONAL PHASE CAUSING LESS OVERALL GROWTH COMPARED TO EXPONENTIAL PHASE

PREDATORS POP. INCREASE ATTRACTS PREDATORS PREDATION KEEPS POP. GROWTH UNDER CONTROL i.e.-RABBITS OUT OF CONTROL, INTRODUCE FOXES

ACCUMULATION OF WASTE MATERIALS CO2 & NITROGENOUS WASTE ACCUMULATES CAUSING MORE DEATH & LESS BIRTH PLATEAU PHASE IS REACHED FASTER VERY HIGH LEVELS TAKE POP. GROWTH BELOW CARRYING CAPACITY

NESTING SITES OVERPOPULATION CAUSES LESS AVAILABLE NESTING SITES DISRUPTS FOOD CHAIN & TRANSITIONAL PHASE IS REACHED FASTER
