Paragraph A Why do organisms need scientific names? And why do scientists use Latin instead of common name to describe organisms? There are several reasons. First, a common name can vary from country to country because different countries use different languages. Second, even people who speak the sar language sometimes use different common names to describe the same organism. For example, the Louisiana heron and tricolored heron are names for the same bird found in southern United States. Furthermore, between countries, the same common name is sometimes given to different organisms "robin" in England is very different from a "robin" in the United States, for example. Latin, on the oth hand, is a universal language that not too long ago was well known by most scholars, many of whom were physicians or clerics. As a result, when scientists throughout the world use the same Latin binomial name, they know they are speaking of the same organism. Find another pattern and show the details. You can use the same pattern you found before if it's a different example. Choose from: Cause and effect Classification Compare/contrast Definition Example Listing Steps in a process
