In the equation N t = N O e rt , what does N o represent?
Options
- APopulation density after time t
- BPopulation density at time zero
- CIntrinsic rate of natural increase
- DNatural logarithm base
Correct answer
B. Population density at time zero
Step-by-step solution
The above equation describes the exponential or geometric growth pattern of a population (Figure 11.3) and results in a J-shaped curve when we plot N in relation to time. If you are familiar with basic calculus, you can derive the integral form of the exponential growth equation asN t = N O e rt whereN t = Population density after time t N O = Population density at time zero r = intrinsic rate of natural increasee = the base of natural logarithms (2.71828)No population of any species in nature has at its disposal u
