  • Daily JumpstartGive examples of nutrients. Why are nutrients essential for living organisms?

  • Next week!Monday your two science articles are due.Monday you will have a quiz on the levels of the biosphere, food webs, and ecological pyramids.

  • In order to survive, a hawk eats 30pounds of lizards in a month. In thatsame month in order to survive, thoselizards have to eat 300 pounds of crickets.How many pounds of grass do thosecrickets have to eat in order to survive?

  • A snake that eats a frog that has eaten an insect that fed on a plant is aa.first-level producer.b.first-level consumer.c.second-level producer.d.third-level consumer.

  • Only 10 percent of the energy stored in an organism can be passed on to the next trophic level. Of the remaining energy, some is used for the organisms life processes, and the rest isa.used in reproduction.b.stored as body tissue. c.stored as fat.d.eliminated as heat.

  • Today Discuss First Biogeochemical CycleWatch Video on CycleCreate Cycle of your EcosystemMake observations of Ecosystem



  • Energy is not the only thingthat moves through the ecosystem.

    Atoms are never destroyed . . . only transformed.

    http://mff.dsisd.net/Environment/Cycles.htmTake a deep breath.The atoms you just inhaled may have been inhaled by a dinosaur millions of years ago.http://educ.queensu.ca/~fmc/august2004/pages/dinobreath.htmlENERGY & MATTER

  • 4 ATOMS make up 95% of the body in most organismsCARBONHYDROGENOXYGENNITROGENElements, chemical compounds, and Other forms of matter are passed fromOne organism to another and from onePart of the biosphere to another in:___________________________BIOGEOCHEMICAL CYCLES

  • Complete for your EcobottleComplete one water for your ecobottle. Use all of the biotic and abiotic factors you have inside your bottles. The classroom environment may also contribute to the cycles.

  • Ecobottle Observations Date: 2/25/11Time:General impressions: This is the first section you complete. Writing should be qualitative and should include observations like: the bottle smells like ??, water color?Each Chamber: Write Quantitative observations. There is 1 fish left. There are now 5 grasshoppers instead of 3. There is a 6 cm ring of mold around the cap.

  • The return of water to the surface in the form ofrain, snow, sleet, hail, etc.= ____________________The evaporation of water from the surface of plant leaves = ________________



  • Cycle ExpertIn your group of 3 you will be an expert on ONE cycle.Gather information from your text book in order to answer the questions.Answer questions in COMPLETE sentences in your NOTEBOOK!Not in a complete sentence? = NO credit

  • Warm-UpHow have we as humans disrupted the water, carbon, and nitrogen cycle?How can we fix this problem?

  • Warm-UpThe movement of water from the surface of a plant is termed?

    2. What is the difference between this and regular evaporation? How are they similar?

  • TodayYou have 10 minutes to finish answering questions.You will then go back to your group and teach your cycle to the group.The rest of the group will listen and write down answers to the questions. NO JUST COPYING ANWERS you must talk out the answers! Water cycle first, then Carbon, then Nitrogen

  • In the nitrogen cycle, bacteria that live on the roots of plantsBreak down nitrogen compounds into nitrogen gas.Denitrify nitrogen compoundsChange nitrogen gas into plant proteinsChange nitrogen gas into ammonia

  • Which of the following is NOT recycled in the biosphere?a.waterc.carbonb.nitrogend.energy

  • What is the process by which bacteria convert nitrogen gas in the air to ammonia?a.nitrogen fixationb.excretionc.decompositiond.denitrification

  • How is carbon stored in the biosphere?a.in the atmosphere as carbon dioxideb.underground as fossil fuels and calcium carbonate rockc.in the oceans as dissolved carbon dioxided.all of the above

  • The movements of energy and nutrients through living systems are different becausea.energy flows in one direction and nutrients recycle.b.energy is limited in the biosphere and nutrients are always available.c.nutrients flow in one direction and energy recycles.d.energy forms chemical compounds and nutrients are lost as heat.

  • Biogeochemical cycling ensures thata.human activity will have no effect on elements, chemical compounds, and other forms of matter.b.living organisms will not become limited in any one nutrient.c.nutrients will be circulated throughout the biosphere.d.many nutrients will not reach toxic concentrations in the biosphere.

  • WHY IS CARBON IMPORTANT?Found in all the _______________ of cells: carbohydrates, proteins, nucleic acids, lipidsImage by Riedellhttp://web.jjay.cuny.edu/~acarpi/NSC/12-dna.htmBUILDING BLOCKS

  • Carbon Cycle QuestionsIn what ways do humans contribute to the Carbon Cycle ?Looking at the diagram you drew, what processes cause carbon dioxide to be released into the atmosphere? What process takes it in?In what form is Carbon found in oceans? Where is it found, and what eventually happens to it?

  • Warm-UpWrite least three questions about any of the topics covered so far in ecology.

  • Review of the Carbon CycleSpeculate on possible pathways a carbon atom might follow over a short and long time and possible reservoirs where the carbon atom might be found.

  • Cut a piece of paper into squaresLabel each paper with a possible reservoir where you think a large amount of carbon would be found in the Earths system.Decide which of the reservoirs represents the largest and smallest reservoir of carbon atoms on a global scale. Write the phrase 'most carbon', and 'least carbon' on that piece of paper.

  • Arrange the 4 papers in a pattern that represents the carbon cycle. Draw in arrows and label the arrows indicating the process that the carbon atom might have to go through in order to move from one reservoir to the other.Ex. atmosphere(photosynthesis)plants
