1. Standard 2 Transfer of Energy in an Ecosystem

2. Objective 2: Generalize the dependent relationships between organisms. a) Categorize the relationships between organisms (i.e., producer/consumer, predator/prey, mutualism/parasitism/decomposer) and provide examples of each. b) Use models to trace the flow of energy in food chains and food webs. c) Formulate and test a hypothesis on the effects of air, temperature, water, or light on plants (e.g., seed germination, growth rates, seasonal adaptations). d) Research multiple ways that different scientists have investigated the same ecosystem.

3. http://youtu.be/E1pp_7-yTN4 Define biotic and abiotic on your paper. Biotic and Abiotic

4. 2:2 Food web Food chains are often too simple to show complex relationships amongst organisms. So we also use food webs. http://youtu.be/KyefVtxY-oI

5. 2:2Producer, Consumer, Decomposer

6. 2:2 Producer and Consumer Relationship Something eating plants.

7. 2:2 Predator/Prey A predator Prey is a relationship where one organism eats another. http://youtu.be/6hGuallLPcM What makes a praying mantis a good predator?

8. 2:2 Decomposers Decomposers break things down. http://youtu.be/ShGF5mkFbzU Name 4 different decomposers.

9. 2:2 Symbiosis http://www.youtube.com/watch?v=zTGcS7vJqb s&feature=share&list=PLpVSLnEyW17bKa2esI HEpr1YNkoQIdBIc&index=1 Name the 3 types of relationships.

10. 2:2 How different scientist study the ecosystem. Biologists look at the living organisms. Botanists look at the plants. Ecologists look at the interactions between the living and nonliving. Meteorologists study weather patterns. Zoologists look at the animals.

11. 2:2 Quiz 1.Draw a food web. 2.What is a producer? 3.What is a consumer? 4.What is a producer/consumer relationship? 5.What is a predator/prey relationship? 6.What are decomposers. 7.Name 3 types of symbiotic relationships. 8.Why is it important that scientist differentiate what they study?
