Definitions: The Food Pyramid • Describes how energy flows through an ecosystem.
Def: Sun – source of energy for the food pyramid. • How do you know it’s a chemical change and not a physical change?
Most of the sunlight is lost…. • It misses the earth entirely or • It hits a spot on the earth without a plant. • The spot warms up and that thermal energy floats up into the sky. • Paraphrase these ideas and place in a box under SUN.
Sun Light Travels to Earth Chemical Energy Light Energy
DEF: PRIMARY PRODUCERS • Plants • Convert sunlight to glucose (sugar) • PHOTOSYNTHESIS • All life on earth is dependent on them.
Sun Light Travels to Earth Chemical Energy Light Energy Most of Light Energy goes into space or does not hit a plant. Sad. Photosynthesis/Plants Chemical Energy
DEF: HERBIVORES • Second level of the pyramid • Animals that EAT PLANTS
*Animal uses energy to move (lost as friction) or to keep warm (heat goes off into space) – all of that energy is hard to use ever again – ENERGY FLOWS Herbivore Chemical Energy in body Thermal Energy* Floats Off Into Space
CARNIVORES! • Well, they are all not dangerous. • THESE ANIMALS EAT OTHER ANIMALS • Third level of the pyramid
*Animal uses energy to move (lost as friction) or to keep warm (heat goes off into space) – all of that energy is hard to use ever again – ENERGY FLOWS Herbivore Carnivores Chemical Energy in body Thermal Energy* Floats Off Into Space
Energy is Flowing through from level to level – most of it is lost. Sad.
Only 10% of usable energy flows onto the next level. • Thus, the higher on the pyramid you are… • The less efficient is your eating. • It takes a lot plants to feed the insects and rodents to feed a hawk. • Write this fact down under Carnivore Def.
DEF: Upper Carnivores You know what I am talking about. LIONS, TIGERS, AND BEARS.
Last in the chain – DEF: DECOMPOSERS • They recycle materials • THEY EAT DEAD ORGANISMS • Mushrooms • Buzzards • Oh My!
Copy and Answer these two questions and then make a pyramid Haiku. • In the food pyramid, we DON’T say “Energy Cycles” because…… • The food pyramid has a wide bottom and small top because _______.
Now its your turn • We need carnivores • and herbivores • and decomposers • and we are going to recreate the pyramid • and experience the food web • in a dance…….
