This is a print-and-go handout that is ready for use to support student’s acquisition of vocabulary related to symbiotic relationships.
This product is six pages of vocabulary set up in the Frayer Model graphic organizer. A teacher can use some of the words or all of them based on the individual needs of their classroom. The following terms are included in this product: symbiosis, mutualism, commensalism, parasitism, predator-prey, predator, prey, beneficial, detrimental, parasite, host and organism.
The handout is designed with a central oval containing the focus vocabulary word and surrounded by 4 squares on the outside. Each square prompts students to a task related to the vocabulary word (write a definition, draw a picture, give an example and give a non-example).

Here is a link to a great resource on how to use the Frayer Model in your classroom if you are unfamiliar with it or want a refresher:
Symbiosis is a close, prolonged association between two or more different organisms of different species that may, but not necessarily, benefit each member. At the middle school level, the focus is on the following symbiotic relationships: predator-prey, mutualism, parasitism and commensalism. In a predator –prey relationship, one organism hunts, captures and consumes another organism (prey). The prey typically has adaptations that help them avoid predation. Examples of organisms in a predator-prey relationship are lion/zebra and polar bear/seal. In a mutualistic relationship, both organisms benefit. Examples of mutualism are clownfish/sea anemone and aphids/ants. Over time two organisms may evolve into one organism, as seen with lichens. Lichen is a plant where strands of algae have linked to the roots and branches of fungus. Together these organisms conduct photosynthesis and obtain minerals from the ground. In this situation, what was once a mutualistic relationship has evolved into a single organism. In a parasitic relationship, one organism (the parasite) benefits and the organism (the host) is harmed. Examples of parasitism are botfly/humans and dodder/shrub. In commensalism, one organism benefits and the other one neither benefits nor is harmed. Examples of commensalism are flatworm/horsecrab and cattle egrets/cattle.
