Review of Food Chains/Webs

Winter Break Assignment Review Jigsaw – Spades Discuss responses to questions 1 through 6 – Clubs Discuss responses to questions 7 through 11 – Hearts Discuss responses to questions 12 to 17 – Diamonds Discuss responses to questions 18 to 22

Habitat vs. Community vs. Ecosystem Habitat – Particular environment in which an organism normally lives Ex. Desert, salt marsh, lake, coral reef, stream, prairie, rain forest, tundra, etc. Community – All the different species within a habitat Ex. Trees, mice, rabbits, wolves, fungi of a forest Ecosystem – All of the living (biotic) AND nonliving (abiotic) factors of an area along with the members of the community

First Let’s Review Different ecosystems have different organisms living there All ecosystems have abiotic and biotic factors – Abiotic= nonliving Ex. Temperature, rainfall – Biotic = living Ex. Plants, animals, bacteria

Today’s Activity Create a powerpoint or prezi presentation to teach the rest of the class about a specific ecosystem and a possible food web that can be found there Step 1 – Roll the dice to determine what type of ecosystem you will be researching – 1- Tropical rainforest – 2- Desert – 3- Deciduous Forest – 4- Coniferous Forest – 5- Artic – 6- Ocean

Today’s Activity (cont) Step 2 – Research plants and animals from this ecosystem and identify/describe (pictures and text) at least: – Two Producers – Three Primary consumers – Two Secondary consumers – One Tertiary (third) consumer – One Decomposer Step 3 – Research at least two abiotic factors that make your ecosystem unique (ex. Extremely low rainfall in desert)

Requirements One ecosystem (from dice roll) presented Slides (pictures + text descriptions) for at least – Two Producers – Three Primary consumers – Two Secondary consumers – One Tertiary (third) consumer – One Decomposer At least two slides (pictures + text descriptions) for TWO abiotic factors (ex. Temperature and rainfall) that make your ecosystem unique This powerpoint will be worth 20 classwork/participation points (same as our giant paper food web group project previously)
