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)
