21. Food Chain!

22. “What’s Eating You?” “Nothing, He’s at the Top of the Food Chain!” Food chains: A path of energy through the levels of an ecosystem Arrows mean “eaten by”! Example: MICE  CATS

23. Explain the wetland food web. Remember… Arrows mean “eaten by”! Example: MICE  CATS

24. With Food Webs, Keep In Mind: A producer is almost always the first step in the food chain! Primary consumers – eat the producers (herbivores) Secondary consumers – eat the primary consumers!

25. Exit Quiz: 1. What is the difference between a primary consumer and a secondary consumer? 2. Which organism is being CONSUMED in the following food chain? Barky  Larky 3. Why do food chains have to start with an organism that is a PRODUCER?
