Bio 270 Practice Population Growth Questions 1 Population Growth Questions Answer Key 1. Distinguish between exponential and logistic population growth. Give the equations for each. Exponential growth is continuous population growth in an environment where resources are unlimited; it is density-independent growth. dN/dt = rN where, dN/dt = change in population size; r = intrinsic rate of increase (= per capita rate of increase and equals birth rate minus death rate); N = population size. Nt = Noert where, Nt = population size at time t; No = original population size, r = intrinsic rate of increase and t = time Logistic growth is continuous population growth in an environment where resources are

1 APES- Chapter #3- Guided Reading Assignment The Big Picture: Systems of Change Name: ____________________________ Period: _______ Due Date: ______________ Summarize the ?Trying to Control Flooding of the Wild Missouri River? Case study People considered the river to be something that was a steady state system and something that could be controlled. This was not the case and it still flooded despite the engineering and money put into the dams and levees. This shows us that it is very hard to try to control nature. Define the following and give examples of each: System: a set of components, or parts, that function together as a whole. Ex. Human body, sewage treatment plant, river

Seartec Trading (Pty) Ltd. Official SHARP importer & distributor for Southern Africa Worksheet 3 Memorandum: Functions ? Exponential and Logarithmic Grade 12 Mathematics CAPS 1. A quantity representing the power to which a number (the base) must be raised to produce a given number. Remember 2. - if powers with same bases are multiplied the exponents are added ? - if powers with the same bases are divided the exponents are subtracted ? - anything to the power of zero is 1 ? - when a power is raised to another exponent ? the exponents are multiplied ? ( ) - when a power is under a root-sign, the exponent of the power is divided by the root-value ? ?
