• Factual: I can interpret a dichotomous key to identify an organism

• Factual: I can design a dichotomous key to differentiate the features of species.

Use the dichotomous key provided in the document below to identify the alien allocated to you (the aliens are shown on the page too).

This video explains how a dichotomous key is designed.

Now try to design your own key to identify the organisms that form the community in a mangrove ecosystem.

More practice of using and designing keys can be found here.
