The key states:
- If the organism is single-celled, go to step 2.
- If the organism is multicellular, go to step 3.
At step 2:
- If the organism has a nucleus, it is an Amoeba.
- If it does not have a nucleus, it is E. coli.
At step 3:
- If the organism produces its own food, it is a fern.
- If it absorbs food from its environment, it is a mushroom.
