Habitats Working Together
See how living and non-living things in Nova Scotia habitats depend on each other.
What your child practises
Practises how plants, animals and non-living things in local habitats such as forests, salt marshes, ponds and dunes depend on each other, including food chains and decomposers. It follows the Grade 4 Nova Scotia science outcome on habitats and touches on the Mi’kmaw idea of Netukulimk.
