2. Food Chain Producer Quaternary Consumer Primary Consumer Secondary
Tertiary
Consumer
The heron is considered a quaternary consumer. Label the trophic levels of each organism in the food chain.
Where does the cattail get its energy?
Explain what the arrows represent in a food chain.
Describe 2 things that would happen if all of the small fish were removed from the food chain above.
Bonus: What biome would this food chain be found in?
Sun
The arrows point in the direction energy flows
Dragonfly population would increase
Catfish population would decrease
Fresh water

3. Food Web Where did all energy in this food web originate from? sun
Place each organism in the appropriate trophic level.
Producer 
Primary Consumer 
Secondary Consumer 
Tertiary Consumer 
Quaternary Consumer
Phytoplankton 
Zooplankton 
Squid 
 Penguin
Killer Whale 
XXXXXXX
 Krill
 Baleen Whale
 Killer Whale
 Leopard Seal

Leopard Seal

4. Food Web
3. Describe the relationship (use vocabulary) between baleen whales and krill. Whale is predator because it eats the krill - prey
4. Describe one path energy could take through this food web. Answers will vary
(Sun  Phytoplankton  Zooplankton  Baleen Whale)
5. Describe 2 things that would happen if there was an increase in the krill population.
The whale, seal, and squid population would increase.
The phytoplankton would decrease.
Bonus: What biome would this food web be found in? saltwater (ocean)

7. Energy Pyramid
4. What happens to the other 90% of the energy that is not passed on from each trophic level. It escapes into the environment as heat/thermal energy 5. What consumer in the energy pyramid is going to have to eat the most food to meet their energy needs? Hawk – tertiary - level 4 6. Describe in your own words why energy in an environment can be represented by a pyramid. More energy is available at the producer level so it is bigger at the bottom, less is available as you go up 7. Create a food chain with the same organisms from above, using words and arrows. Sagebrush  Insects  Lizard  Hawk

8. Composting
Why is composting good for the environment? Composting is the healthiest fertilizer; Cuts back on garbage in landfills
Why is it important to have green and brown in a compost bin? So it is rich in both carbon (brown) and nitrogen (green)
Use the T chart to sort things that should and should NOT be in a compost bin. (on next slide)
What happens to the biomass of a compost bin? Biomass decreases as it is decomposed
What happens to the temperature of a compost bin over time? Temperature increases in a compost bin over time
What energy conversion happens in a compost bin? Chemical energy  heat/thermal energy
What type of organism breaks down biomass in a compost bin? Decomposers (microorganisms, worms)
