What are the negative effects of population growth?
If it is too high for the world to sustain then starvation, war and death
What are exponential growth and logistic growth?
Exponential Growth: occurs when the individuals in a population reproduce at a constant rate.Logistic Growth: occurs when a population's growth slows or stops following a period of exponential growth around a carrying capacity.
Formula for population growth without limits?
The formula for population growth is based on the formula for interest. The formula is Final Population is equal to Initial Population multiplied by e raised to the power of the product of the rate of growth multiplied by the time of growth, or P(f) = P(o) * e ^ (rt).
What is the difference between linear and exponential population growth?
Linear growth: The population adds the same number every week/month/year.Exponential growth: The population multiplies bythe same number every week/month/year.
Compare exponential growth with logistic growth?
Exponential growth occurs when numbers increase by a certain factor in each successive time period. Logistic growth is population growth that starts with a minimum number of individuals and reaches a maximum depending on the carrying capacity of the habitat. In exponential growth population grows slowly when it's small, but as the population gets larger, growth speeds up. In logistic growth, when the population is small, the growth rate is fast because there are plenty of natural resources. (Logistic) As the population approaches the carrying capacity, resources become scarce. Completion for food, shelter and mates increases between individuals of a population. As a result, the growth rate slows. Exponential growth, grows fast in the beginning and then slows down. Logistic growth grows slow in the beginning and then speeds up.
