Habitats & Basic Needs

Science · Ecosystems & Habitats · conceptual

Identify that most living things live in habitats to which they are suited and describe how habitats provide for basic needs and how organisms depend on each other

What mastery looks like

  • Define a habitat as a place where an organism lives that provides what it needs
  • Give examples of how specific habitats meet organisms' needs (e.g. pond provides water and food for frogs)
  • Describe at least one way organisms in a habitat depend on each other (e.g. bees pollinate flowers, flowers feed bees)

Check your understanding

Can Habitats & Basic Needs explain why a polar bear lives in the Arctic and not in a desert, and how the animals and plants in a habitat help each other?
