Week 10 addendum

Hmm. I wish that I had been in class last week to refresh my recollection of what constitutes a "species" (family, genus, species . . .). I know that my environment is teeming with microscopic organisms, but I don't remember if they are "species." Anyway, there are humans in my home. And, thanks to my husband, there are three living plants in my home, each of a different variety. We have a small backyard that is visited every night by raccoons and every morning by at least three varieties of birds. The soil in our garden contains some earthworms. Ants and spiders roam around outside. A mystery creature visits the garden and eats all of the vegetables and herbs, except the parsley.
