1. Warm up activity Match the pictures to the correct terms that describe them:  ____Ecosystem  ____biome  ____biosphere  ____Population  ____Communities  ____Individual organism 1 2 3 4 5 6

2. Lesson 1: Intro to Ecosystem  Level of organizations in an ecosystem  Biotic vs abiotic factors  Food chain  Food web  Interdependence in ecosystem- case studies

3. This picture illustrates a/an: a.Population b. community c. habitat d. ecosystem? What is an ecosystem? A complex, self-regulating system in which Living things interact with each other and with non- living things

4. Abiotic vs. Biotic factors in this ecosystem? Abiotic (non-living) factors Biotic (living) factors -Sunlight -Water -Oxygen gas -pH -Soil -Dead wood -Deers, fish, frogs -Plants -microorganisms

5. Organize the terms you have seen from the most specific to the broadest:  Ecosystem  biome  biosphere  Population  community  Individual organism Ecosystem - Levels of organization Most specific Broadest

6. Organize the terms you have seen from the most specific to the broadest:  Ecosystem  biome  biosphere  Population  community  Individual organism Ecosystem - Levels of organization Most specific Broadest

7. Species (groups of individual organism) Individuals of the same species form a Population Populations of different species come together to form Communities Communities comes together to form Ecosystems Ecosystems comes together to form the Biomes Biomes come together to form the Biosphere Ecosystem Levels of organization

8. Types of ecosystems

11. Exploring how producers & consumers are connected by building a food web This is a food chain Food chain = The feeding relationship among organisms in an ecosystem means “eaten by”; showing how energy is passed on from each living thing in an ecosystem

12. Food chain and food web Watch “Food chain & web” videos and answer: 1. What is a food web? A food web is a diagram showing connecting food chains in a community 2. How is a food web different from a food chain? A food web is bigger than a food chain; there are many food chains in one food web -Circle the food web and a food chain in the picture

13. Food web Food chain

14. Recall from previous class: Organisms Consumers Producers Organisms that produce their own food using the Sun’s energy Organisms that consume others for energy Producers = Consumers = autotrophs heterotrophs

15. A carnivore that preys on secondary consumers is called a tertiary consumer. A fox feeding on a snake is a tertiary consumer. Carnivores occupy the third and fourth trophic levels. A carnivore that preys on primary consumers is called a secondary consumer. A snake that eats a mouse is a secondary consumer. Herbivores occupy the second trophic level. These plant-eating consumers, such as mice that eat seeds, are known as primary consumers. Producers, such as grass or algae, occupy the first trophic level. First trophic level producers second trophic level primary consumers third trophic level secondary consumers fourth trophic level tertiary consumers Trophic level: the feeding position of an organism in a food chain.

17. Photosynthesis (PS) and Cellular Respiration (CR) - 2 complementary processes that move energy through ecosystems PS and CR are complementary processes because: The starting materials of one reaction are the results of the other reaction Starting materials = reactants Resulting chemicals = products

18. Next section: Exit cards to be done after popcorn activity

19. Exit card: Connect trophic level to today’s intro activity Sun= the ultimate source of energy for ecosystems
