1. Mr. Ted's Science Class January 24th, 2016 What are we learning today? Unit 8: Ecological Relationships I will be able to: (1) Identify components of food chains and food webs (2) Describe the flow of energy in food chains (3) Define: habitat, extinction, endangered, food web Identify: التعرف Components: المكونات food chain: سلسلة غذائية Food web: الشبكة الغذائية Describe: وصف energy: طاقة Define: حدد habitat: الموائل extinction: انقراض Ecological: الإيكولوجية Relationship: علاق endangered: المهددة:

2. Ecological Relationship Ecological Relationship: It is the relationship between living organisms and to their surrounding environment Ecological: الإيكولوجية Relationship: علاق Organisms: كائن حي environment: بيئة

3. Ecological Relationship Habitat: the natural home or environment of an animal or plant natural: طبيعي: habitat: الموائل environment: بيئة

4. Ecological Relationship What happens when your habitat becomes destroyed? Habitat: habitat: الموائل destroyed: دمرت

5. Ecological Relationship Extinction: When all of one type of animal or plant (specie) dies Extinction: انقراض Specie: مسكوكة

6. Ecological Relationship Endangered: When the number of one type of animal or plant (specie) becomes near to extinction Endangered: المهددة: Extinction: انقراض Specie: مسكوكة

7. Ecological Relationship Food chain: The feeding relationship between animals and plants (organisms). Food chain: سلسلة غذائية: Feeding: تغذية relationship: Relationship: علاق Organism: كائن حي

8. Ecological Relationship How does energy transfer in a food chain? Energy: الطاقة transfer: نقل السلطة Food chain: سلسلة غذائية:

9. Ecological Relationship Food web: A system of food chains that are dependent on each other Food web: الشبكة الغذائية Food chain: سلسلة غذائية system: نظام: dependent: تعتمد

10. Mr. Ted's Science Class January 24th, 2016 What did you learn today? Unit 8: Ecological Relationships What is the difference between a food chain and a food web? What is happening in a food chain? What do the arrows in a food web mean? How does energy/ nutrient travel in a food web? What is: habitat, extinction, endangered, food web?

11. Fact of the Day A food chain shows the feeding of different organisms in an ecosystem Animals are often part of more than one food chain A food web consists of organism that belong to different food chain The arrows in the food web: –shows the direction of energy flow –shows the direction of nutrient flow –shows the relationship 'is eaten by'
