Ecosystems and Biomes: Who Depends on Whom Grades 6–8

Real wolf and moose counts from Isle Royale, a sixteen-card sort of competitors, predators, parasites and partners, six real climate graphs to match to their biomes, and a sea wall against a salt marsh. Four print-and-go lessons on populations, interactions, biomes and the services ecosystems give us.

• Are living things competitors, predators or partners? 50–60 min

  Teams sort sixteen real pairs of living things, from coral reefs, savannas, forests and deserts, into competition, predation, parasitism, mutualism and commensalism, then stand in the room as a human chart to find the pattern. They explain why the same five kinds of interaction turn up in every ecosystem on Earth.
