9.22.14 Flow of Energy Diagrams

Which gases move in and out of the plant leaf through the stomata?

OBJ: 7.5C We will diagram the flow of energy in our science journals by using manipulatives to create food chains, food webs, and energy pyramids.

S

Food Web Video1) What is a food web made of?2) What do herbivores, secondary consumers, and omnivores

eat?3) What does a food web help us understand?4) What would happen if some organisms were removed from a

food web?

P

A & C Demonstrate Energy Flow

Using the class set. 1. Create 2 different food chains using the organisms . Draw and label them in your notebook. 2. Create a food web using all the organisms. Draw and label in your notebook. 3. Create a energy pyramid. Starting with the producers at 100,000 Kcals. Draw and label.

Summary

What did you do today in class? Why are food chains, food webs, and energy pyramids important? What else did you learn?
