The web of life
An ECOSYSTEM is a community of living things and their surroundings, and this puzzle gathers how it works. You'll be finding the roles every living thing plays — the PRODUCER that makes food, the CONSUMER that eats it, the DECOMPOSER that recycles it, and the PREDATOR and PREY in the FOOD CHAIN.
Because every new puzzle reshuffles nature, no two ecosystems word searches are the same. One round a backwards DECOMPOSER hides in a corner; the next a diagonal ADAPTATION appears across the middle.
Biomes big and small
Ecosystems come in every size, and the words are here. Explore the great BIOMEs — the FOREST, the WETLAND, the TUNDRA, the SAVANNA and the CORAL REEF — and learn how ENERGY and NUTRIENTS flow through a FOOD WEB. There's the HABITAT each SPECIES calls home, the NICHE it fills, the POPULATION and COMMUNITY it belongs to, and the ADAPTATION that helps it survive.
It's a great fit for a science or geography topic on living things. Tracking down D-E-C-O-M-P-O-S-E-R turns spelling practice into a nature lesson.
How to play
Drag across a word, or click its first and last letter — both work. Each word you spot locks in with its own colour and ticks off the list, so you always know what's left to find.
