Food Chains 4.L.3.1. Students are able to describe the flow of energy through food chains and webs.

A producer is an organism that gets its energy from the sun. Example: sunflower plant.

Decomposers are organisms that eat dead or decaying organisms. They carry out the natural process of decomposition. Fungi is the primary and most common.

FOOD CHAINS AND FOOD WEBS THE ENERGY CONNECTION ntbk pp 22-23

Food chains Explain a food chain. SHOWS 1 path that energy can move First is always producer (a tree) Second organism feeds on the producer. This is a first level consumer (primary consumer) (carpenter ant) Second level consumer (secondary consumer) eats a first level consumer. (woodpecker) TREE CARPENTER ANT WOODPECKER

Food Webs How does a food web work? Consists of many overlapping food chains in an ecosystem an organism may have more than one role Most consumers and producers are a part of multiple food CHAINS

Brain Pop Food Chains Answer the quiz questions as we watch the video.

Make your own Food Chain Use the materials to create your own food chain. THIS SHOWS ONLY 1 THING THAT EATS ANOTHER; ONE PATH!! DON’T FORGET THE SUN!!!!! Make another food chain- share it with your neighbor- DON’T GLUE ANYTHING YET!!

Make it into a food web Now make a food web with other organisms you have- Put your organisms on the paper Connect them with lines/arrows to show what they all MIGHT eat! Does a polar bear eat a giraffe??? MAKE SURE YOUR WEB FITS IN THE RIGHT HABITAT. Look at your book for ideas- pp
