1. Warm Up 9
3/23
Which of these organisms gets the most energy from the sun? Least energy from the sun?
Name the primary consumers.
Name the organisms in the fourth trophic level.

2. End of 3.2, Beginning of 3.3 Energy Pyramid Biogeochemical Cycles
Water Cycle

3. Ecological Pyramid
Diagram that shows the amounts of energy or matter in each trophic level

4. Energy Pyramid
Shows the amount of energy at each trophic level

5. Only 10% of energy available in one trophic level is transferred to organisms at the next trophic level

6. Only 10% is transferred from each level because
Organisms use much of the energy they consume for life processes like respiration, movement, and reproduction

7. Cycles of Matter Review
Matter is generally considered to be anything that has mass and volume
Everything is made up of matter
Elements
Chemical compounds

8. Bio.Geo.Chem-ical Cycles
Process where elements, chemical compounds, and other forms of matter are passed from one part of the biosphere to another
Water Cycle
Carbon Cycle
Nitrogen Cycle

9. Movement of matter vs. Flow of energy
Matters recycle within & between ecosystems in biogeochemical cycles
One way flow of energy

10. Water Cycle
Stored in: Land, Atmosphere, Ocean

11. Evaporation- change from liquid to gas
Transpiration- evaporation from leaves of plants
Condensation- water vapor condenses into droplets that form clouds
Precipitation- rain, snow, hail
Runoff- water flows to surface from rivers/streams to ocean/lakes
Seepage- seeps into the soil to become groundwater

13. Review
What do energy pyramids show?

14. Draw an energy pyramid for a five-step food chain
Draw an energy pyramid for a five-step food chain. If 100% of the energy is available at the first trophic level, what percentage of the total energy is available at the highest trophic level?
