Step5: Identify organisms with pleasant odor

Roses have a pleasant odor, so the scientific name is Rosa.

Step6: Identify organisms with unpleasant odor

Skunks have an unpleasant odor, so the scientific name is Mephitidae.

Step7: Identify organisms seen during holidays

Pine - trees are commonly seen during holidays like Christmas, so the scientific name is Pinus.

Step8: Identify organisms with valuable fashion items

Eagles' feathers have been used in fashion in some cultures, so the scientific name is Aquila chrysaetos. Also, cows' leather is used in fashion, so the scientific name is Bos taurus.

Step9: Identify organisms seen on a farm
