THE CURIOSI · EXPLORE & TRY
Compare broad environmental patterns
Explore the model, then test your understanding. Select each numbered stop to discover its role.
1Desert
Deserts receive little precipitation; some are hot and some are cold.
2Forest
Forests have many trees, but climate and species differ among forest types.
3Grassland
Grasses are common; rainfall, fire and grazing can influence the balance of plants.
4Freshwater
Lakes and rivers have low salt content compared with oceans.
5Ocean
Ocean habitats vary with depth, light, temperature and other conditions.
Simplified model: real ecosystems have more connections. Food-chain arrows show energy moving from food to eater; nutrient-cycle arrows describe material transfer.
