Food Chains, Webs and Energy Pyramids by Peter - 5:33
The following video was created by my MST student: Peter. This video looks at Food chains, Food webs and Energy Pyramids. We look at the types of organisms found at various trophic levels as well as the movement of energy through a food chain. For more STS videos, check us out on iTunes by searching "Papapodcasts". Thanks for watching.
