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)
