Unit 1: Understanding Life Systems - Habitats and
This strand focuses on habitats, the natural communities that depend on them, and the impacts
that changes to habitats can have on interrelationships among plants and animals within these
communities. Students will learn that living things (including humans) rely on other living things
for the energy and resources they need to live. They will also investigate factors that alter various habitats and communities, including those factors that occur naturally and those that result from human action.
