1. Ecology Food Chains and Trophic Levels

2. Questions: 1.Give an example of a PRODUCER that you like to eat! 2.When you eat this producer, what are you considered to be? 3.Give an example of a CONSUMER that you like to eat! 4.When you eat this consumer, what are you considered to be?

3. Let’s Think… Algae  salmon  shark Which is the producer? Which is/are the consumer(s)? How do you know? Whangdoodle  whippersnapper  whatchamacallit Which of the following is the producer? Which is the primary consumer? Which is the secondary consumer?

6. So…what’s a trophic level? Trophic Level – the trophic level of an organism is the position that it holds on a food chain. A trophic level represents the amount of ENERGY that an organism receives from the level below it!

7. TROPHIC LEVELS!

8. PLANTS HERBIVORES CARNIVORES / OMNIVORES

9. Example of Trophic Levels: Where do each of these organisms fit on the pyramid? Why? Grasshopper, snake, wheat, frog

10. Critical Thinking Questions: Why do you think the largest part of the trophic pyramid is the producers? Why are there so few tertiary organisms in the trophic pyramid?

11. Questions: 1. What is a trophic level? (DO NOT WRITE THE DEFINITION! PUT YOUR ANSWER IN YOUR OWN WORDS!) 2. Why are there more plants on this earth than any species of animal?

12. Scavenger Hunt! FIRST: determine which organism fits at each level of the food chains! Use the information at each station to help you! NEXT: Determine which organisms will fit at each of the trophic levels on the pyramid on the back of your handout THEN: ask Ms. Yassin to check your work!
