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