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.

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

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

Energy Pyramid Shows the amount of energy at each trophic level

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

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

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

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

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

Water Cycle Stored in: Land, Atmosphere, Ocean

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

Review What do energy pyramids show?

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?
