Geometric growth refers to the growth of populations that do not have overlap in their generations. Annual plants and some insects are good examples where adults die before young individuals mature to reproduce. Pacific salmon are an example of a vertebrate with geometric growth because spawning (egg laying). The equation for geometric growth is: N=No; where A= finite rate of increase and t=number of time intervals. Question A1. Calculate the population size after 10 time intervals (N10) if No = 120 and 2= 1.1. Question A2. If N1 = 750 and N2 = 890, calculate

Communities and Ecosystems

Ecology contains two words: Eikos means dwelling, and logy means to study, so the combined meaning is studying habitat or living.
