Ecology of the environment

- Mark and recapture - Demography - Mortality rate - Fecundity - Interspecfic competition - Age structure - Intraspecific competition A. The probability of individuals dying before their next birthday B. The proportion of individuals of a population at specific age ranges C. Used to determine population size of mobile organisms D. Species contending for resources in a shared habitat E. The potential reproductive capacity of an individual within a population F. Members of the same population of organisms contending for resources G. A description of how an organism maintains and reproduces itself from its birth until its death H. The statistical study of population changes over time I. The total number of individuals of a species worldwide J. The number of individuals within a specific area K. A sampling method used to determine population size and density of slow moving or stationary organisms Instructions In this unit, you learned that the characteristics of a population at a given time can be represented graphically using birth and death rate data, among many other parameters. In Part I of this activity, you will work with a simple data set to create a human survivorship curve and answer questions about the results and the data itself. In Part II, you will work with interactive age structure diagrams in an online simulator to analyze population growth trends for both China and the United States. For an example of an age structure diagram, see the presentations for the Unit II Lesson.
