Symbiotic relationships: Who wins, who loses? • Killer wasps • The cassowary • Parasite got your tongue? • A dog’s life
Key Concepts:
Some living things live in symbiotic relationships that either benefit both partners or just one of them. Symbiotic relationships can change and evolve over time. Symbiotic relationships are important for the survival of the living things involved and sometimes for whole ecosystems.
Reading Strategies:
Use combined knowledge of all letter-sound correspondences, syllabication patterns, and morphology (e.g., roots and affixes) to read accurately unfamiliar multisyllabic words in context and out of context.
