Differentiate between exponential and logistic growth curves. Give examples of the conditions under which each would occur
What will be an ideal response?
Exponential growth (a J-shaped curve) occurs when there are no limiting factors. This occurs when a population is small and environmental conditions are ideal for the organism in question. Mold on a piece of bread and bacteria colonizing a dead animal are examples. Logistic growth (S-shaped growth curve) rises exponentially at first and then begins to level off as the effects of limiting factors, or environmental resistance, become stronger. A population introduced into a new environment where there are other organisms will experience limitations quickly, and these limitations will limit the population growth.
