Scientists have discovered over a million different species of living things on Earth, but they estimate there could be as many as nine million in total. That means there are millions of species still to be discovered. All over the world, even in the most difficult and extreme environments, we find life. The life on Earth is hugely varied, from the mold growing on your food, to human beings, to mushrooms in the woods. Scientists have devised a way of classifying these organisms, not only to organize them, but also to highlight similarities and differences.
Have students research different organisms and compare the two using their taxonomic rank and defining characteristics.
The Classification of Organisms
Directions: In the columns below, research the two different organisms. Include their taxonomic classification, any distinct features that place them into their ranks, and their habitat. Then, identify the things that are similar between the two on the lines provided.
