  1. Habitats and Ecosystems Objective: To discuss how a habitat, community, population and ecosystem relate to each other.

  2. Thinking about your habitat... • What is a habitat? • What are the basic things that everyone needs for survival? • Think about the things that make up your habitat. • How are your needs met? • How much space do you use? • What about the longer-reaching impacts of meeting your needs (e.g. Food – from a supermarket – from a farm).

  3. Population and Community Population Community • A group of organisms of the same species that live in the same habitat. • Example: A population of lions inhabit the savannah desert. • A community is composed of two or more populations (species) that have a specific role in the area where they live. • Communities of plants, animals, and other organisms that may be found in the desert are grass, shrubs, lions, zebras, hyenas, etc.

  4. Drawing an ecosystem • Copy the diagram for the habitat of a lizard. • Label the three main requirements of a habitat. • Complete the drawing to form an ecosystem. • Label the biotic (living) and abiotic (non-living) factors. • Label the community, population and ecosystem that exist in the diagram.
