PART I: Class Activity Time!

How can we learn a whole lot of new stuff without awhole lot of effort?

EASY - just try memorize (or take quick notes) on 3of the next 10 slides! Do this with 1 or 2 partners ifyou like. Your effort will be rewarded in a gameafterwards!

The next 10 slides are about: Ecosystems (3 slides) Zonation (3 slides) Energy (4 slides)

READY?

1. Ecosystems are …

All members of a community, along withtheir physical and chemical environments.

They … Vary greatly in size Are Dynamic

energy flow chemical cycling

Change over time(called succession)

Coral Reefs are rich, diverse andproductive ecosystems

Dude! Am Ibiotic orabiotic or

wut?!

2. Aquatic Ecosystems (types)

Freshwater Flowing Water Lakes

Wetlands

Estuaries

Oceans (see next slide)

Kawainui Marsh

I’m looking forwaterfront,quiet kine

‘hood … l’dat!

3. Ocean Ecosystems

Ocean Zones Intertidal or

littoral Coastal or neritic Coral Reefs Open Ocean Benthic

Queen’s BathKalapana

4. Zonation in Lakes 5. Zonation in a Marine Environment

6. Zonation in a Loko Pu‘uone (type of Hawaiian fishpond) All ponds are in the Photic Zone

Ponds include Intertidal &/or Littoral Zones Benthic zone of ponds has many organisms living

off decomposing organic matter Eurtrophic lakes are more shallow & have rich

nutrients

7. Primary Production (Light Energy)

The conversion of lightenergy to chemical energy iscalled photosynthesis.

Plants use the energycaptured in photosynthesisfor maintenance and growth.

The energy that isaccumulated in plant biomassis called “net primaryproduction.”

8. Energy Flow in Ecosystems

Producers of Energy (Autotrophs)

Consumers of Energy (Heterotrophs)

Trophic Levels Ecological Pyramids of Energy Ecological Pyramids of Biomass Ecological Pyramids of Numbers

9. Ecological Pyramid of Energy

Mm-mm … Icould really go

for somekilocalories…

10. Ecological Pyramid of Biomass

Hey…. Notme brah - Iam way low

cal!

Get Ready for the Game!Make a sheet with 2 columns & 8 rows like this:

Name: 1.

Name: 2.

Name: 3.

Name: 4.

Name: 5.

Name: 6.

Name: 7.

Name: 8.

Bring on the game!

On the next slide 8 tasks will appear. Do not writethem down. Just read them & get ready to go lookfor 8 different people who can do these tasks. Youcan only write your own name beside one task.

Each person must PROVE they can do the task beforethey can sign your paper.

The first person with their sheet filled in with 8different names WINS!

Get it?

Good … GO!

Hurry! The clock is ticking!Name: 1. Recite 3 types of aquatic ecosytems from

memory.Name: 2. While standing on 1 foot, read aloud from

your notes for 20 seconds.Name: 3. Put these photic zones in order as seen

from shore: neritic, oceanic, intertidal.Name: 4. Recall a dream you have had about water &

relate it to 1 fact you learned in this class.Name: 5. State the mathematical pattern of

kilocalories of energy between primaryproducers & all 3 consumer types.

Name: 6. Make up & sing a 10 second song aboutzonation.

Name: 7. In less than 30 seconds state 3 factsabout an aquatic ecosystem.

Name: 8. Draw one of the diagrams you’ve just seen.

PART 2: Biogeochemical Cycles

Coming up next …

Cycling of materials between theenvironment and organisms

Chemical and biological processes

Examples Water cycle Nitrogen cycle Phosphorus cycle Carbon cycle

Plants obtain nitrogenfrom nitrogen-fixingbacteria and pass it to

other organisms throughthe food chain.

Biogeochemical Cycles

“Bio” means life. “Geo” means earth. Tell us about the chemicalcycles of life on Earth in … Group Activity Time!

Get into groups of 2-4 Study the diagram on the handout you are given (water cycle,

nitrogen cycle, phosphorus cycle or carbon cycle) Choose 1-2 people to prepare to do each of these tasks in front

of the class (everyone must help present): Choose, state and explain a title for your diagram Pronounce and define new words or terms Explain in simple language how many steps are shown in your

diagram and what is happening at each step Guess who this information is important to and why (not

just “scientists” or “nature” … be specific & think deeply!)
