Human Population Growth

If the carrying capacity for a population is 6,000 that means that

• The 6,000 will be the number of years it takes for the population to reach its growth limit

• The species will go extinct if the population surpasses 6,000

• The population will stay well below 6,000

• Individuals will start to die off if the population surpasses 6,000

What is this graph illustrating?

• A population will go extinct once it reaches its carrying capacity

• A population starts off at its carrying capacity, but then grow exponentially

• A population will start to grow quickly, but then growth will slow as the population reaches its carrying capacity

• A population will grow, but then decrease sharply once it reaches its carrying capacity
