This activity is great review for state mandated tests. There are twelve cards that give hints that students should be able to use to decide whether the organism described is a consumer, a producer, or a decomposer. The clues all relate back to the definition and characteristics of each of the three organisms in energy webs. There is a definition sheet for each type of organism and also an answer key. Meets NGSS and TEXAS TEKS Resource system..4.9b and 5.9b. Easy to use. You can get this ready quickly, use it as a whole class activity or put it in a science center for review work or for assessment. Enjoy.
