    1. Ecosystems and Food Chains

    2. Flashback Questions What is the first step of the scientific method? Name one structure of an animal and its function.

    3. SC-04-4.6.1 Plants make their own food. All animals depend on plants. Some animals eat plants for food. Other animals eat animals that eat the plants. Basic relationships and connections between organisms in food chains, including the flow of energy, can be used to discover patterns within ecosystems

    4. ORQ

    5. Let's see what you already know about ecosystems ...

    6. You also need to know… Population Community Niche Biome Energy transfer Energy pyramid Environment Food web

    7. Ecosystems Groups of living things and the environment they live in make up an ecosystem. All living things can meet their basic needs there. Ex. Beaver pond, ocean, forest, parking lot

    9. Communities Communities are made up of all the populations that live in the same area. The plants and animals that live together depend on one another to survive.

    10. Populations A group of the same species living in the same place at the same time. Ex. Tadpoles, deer, trout

    11. Habitat A habitat meets the needs of an organism. Habitats may include small parts of an ecosystem or the entire ecosystem. Ex. Birds often use the entire ecosystem, while a fungi may only need a log in the ecosystem to meet its needs.

    12. Animal Niches Animals have a niche or job they perform in a habitat. Niche- an animal’s job in its environment, which includes all the ways it meets its basic needs How it gets shelter How It produces young How it gets food and water.

    13. What an organism eats is an important part of its niche because what a living thing eats affects the population around it. The sun is the main source of energy for all living things. Animals do not get their energy directly from the sun, but they eat plants, which use sunlight to make food. Some animals eat other animals that eat plants.

    14. Hmmm…If our school were an ecosystem… What communities could we have? What populations are in those communities? Do these populations depend on each other? Does each member of the community have a niche?

    15. Remember… This PowerPoint study guide, along with ecosystem games and simulations can be viewed on Mrs. Barnard’s TeacherWeb page. http://www.teacherweb.com/KY/LondonElementary/MrsBarnard/

    16. Exit Slip Questions Everything that surrounds a living thing is its _________________. The specific role of an organism in its habitat is its _______________.
