7th POE- Energy Flow in Ecosystems Day 2

​POE- Energy Flow in Ecosystems- Food Chains vs. Food Webs

​1. Grab four notecards
2. Word on the FRONT
3. Definitions on the BACK
4. Add to the back with the notecards from yesterday

​1. Food Chain- shows how energy moves through the ecosystem when one organism eats another organism.
2. Trophic level- each organism in the food chain represents a transfer of energy
3. Food webs- all the possible energy transfers. Basically all the food chains in a community linked together
4. Ecological pyramid- a diagram that shows the amount of energy at each trophic level.

​GET READY!!!!!

Multiple Choice

Food Chain-

• shows how energy moves through the ecosystem when one organism eats another organism.

• Does not show how energy moves through the ecosystem when one organism eats another organism.

• Occasionally shows how energy moves through the ecosystem when one organism eats another organism.

Multiple Choice

Trophic level-

• each organism in the food chain represents a transfer of energy

• some organism in the food chain represents a transfer of energy

• each organism in the food web represents a transfer of energy

Multiple Choice

Food webs-

• all the possible energy transfers. Basically all the food chains in a community linked together

• all the possible energy transfers. Basically all the food chains in a population linked together

• all the possible energy transfers. Basically all the food chains in a biome linked together

Multiple Choice

Ecological pyramid-

• a diagram that shows the amount of energy at each trophic level.

• a diagram that shows the amount of energy at each ecosystem level.

• a diagram that shows the amount of energy at each community level.

​PAY ATTENTION!!!

FOR YOUR MINI POSTER PROJECT YOU WILL:

​1. IDENTIFY THE NUMBER ONE SOURCE OF ENERGY ON EARTH
2. PRODUCERS
3. PRIMARY CONSUMERS
4. SECONDARY CONSUMERS
5. TERTIARY CONSUMERS
6. DECOMPOSERS
7. FOOD CHAIN
