These seven ranks are mixed up: Order, Species, Phylum, Family, Kingdom, Genus, Class. Write them from the biggest group to the smallest. Which holds the most organisms, and whose members share the most features?
Need a reminder? The key ideaShow
The ranks from the smallest: species, genus, family, order, class, phylum (division in plants) and kingdom. A group at any rank is a taxon. Going up, a group holds more organisms that share fewer features. A species is a group with fundamental similarities, whose members can breed and have fertile young.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. In order. Kingdom, Phylum, Class, Order, Family, Genus, Species.
Step 2. Most organisms. The kingdom.
Step 3. Most features shared. The species, whose members are the most alike.
Answer: Kingdom, Phylum, Class, Order, Family, Genus, Species.
