Understanding Energy Flow in the Biosphere

Dive into the intricate systems of biology, from molecules to organisms and ecosystems. Explore the relationships between living organisms and their environments to grasp the dynamics of energy flow. Follow the journey from cells to biomes, understanding how life thrives and sustains itself in the biosphere. Discover the key concepts of ecology and habitat interactions that shape the world around us, all within the fascinating realm of biology.

  1. Energy Flow in the Biosphere, Chapter 3-1 & 3-2 http://www.geog.uni-heidelberg.de/~ttavk/weltkarten/globen/1997-1998-biosphere-Nasa.jpg

  2. REMEMBER CELL BIO

  3. INTEREST GRABBER- THINK BACK TO CHAPTER 7 ________ __________  ___________ MOLECULES ORGANELLES ATOMS IMAGE SOURCES: see last slide

  4. ____________  ____________  CELLS TISSUES Similar cells working together IMAGE SOURCES: see last slide

  5. ___________  __________ ___________ ORGAN SYSTEMS ORGANS ORGANISM Different tissuesworking together Different organsworking together IMAGE SOURCES: see last slide

  6. ___________________________________ ORGANISMS POPULATIONS COMMUNITY SAME SPECIESLIVING TOGETHER IN AN AREA Ex: “herd” DIFFERENT POPULATIONS LIVING TOGETHER IN AN AREA BIOLOGY; Miller and Levine; Prentice Hall;2006

  7. _______________________ _____________ ECOSYSTEMS BIOMES BIOSPHERE All the organisms that live in a place together with their NON-living environment Group of ecosystems that have same climate and similar communities The portion of the planet in which all life exists IMAGE SOURCES: see last slide

  8. SPECIES Organisms so similar to one another that they can breed and produce fertile offspring = _____________ http://suedafrika.net/bluegifs/twooryx.jpg

If you breed them, the result is a mule which can NOT have offspring!

  10. The scientific study of interactions of organisms with each other and with their environment = ______________ The portion of the planet in which all life exists = _________________ (includes land, water, atmosphere) ECOLOGY BIOSPHERE Extends from about 8 km above the Earth’s surface to 11 km below the ocean’s surface http://jaeger.earthsci.unimelb.edu.au/Images/Topographic/Whole_Earth/Earth_100.jpg

  11. WHAT SHAPES AN ECOSYSTEM? BIOTIC FACTORS __________________ All the living things an organism interacts with __________________ All the non-living things that affect an organism Ex: climate, temperature, sunlight soil, humidity, wind ABIOTIC FACTORS Images from: Pearson Education Inc; Publishing as Pearson Prentice Hall

  12. HABITAT __________________ = The area where an organism lives A rattlesnake lives in a desert in the American Southwest http://animals.timduru.org/dirlist/snake/animalwild089-RattleSnake-FaceCloseup.jpg http://www.rvstogophx.com/images/arizona_desert_sm.jpg

  13. NICHE _____________ = place it lives PLUS the _____________ & ______________ interactions it has in that place NICHE includes: Where it lives PLUS . . . What it eats? What eats it? Where in the habitat it lives?In a tree, in a pond,underground Its actions… hibernating, migrating, etcWhen & how it reproduces? biotic abiotic

Habitat is like an organism’s ____________ Niche is like an organism’s ______________ address OCCUPATION http://resmedicinae.sourceforge.net/logos/doctor.png http://www.michcampgrounds.com/yogibears/yogi-picnic-cartoon.jpg http://www.formaui.org/kamalii/critters.htm

  15. NO TWO SPECIES CAN SHARE THE SAME NICHE ! Competitive exclusion principle = ______________________________ BIOLOGY; Miller and Levine; Prentice Hall; 2006

  16. The Earth is SOLAR POWERED! ALL LIVING THINGS USE ENERGY _____________ is the main source of energy for life on Earth. SUNLIGHT http://www.animation-station.com/smileys/index.php?page=17

  17. AUTOTROPHS = PRODUCERSCan make their own food ALL LIVING THINGS USE ENERGY Most autotrophs use _______________ to capture solar energy Main producers on land = green plants In water = algae PHOTOSYNTHESIS BIOLOGY; MIller and Levine; Prentice Hall; 2006

  18. absence of light Some autotrophs can make own food in the ____________________ They use energy stored in ________________ of ______________________to produce carbohydrates = ___________________ Ex: Bacteria that live in HOSTILE places Like volcano vents, hot springs, marshes chemical bonds INORGANIC MOLECULES CHEMOSYNTHESIS BIOLOGY; MIller and Levine; Prentice Hall; 2006

  19. CONSUMERS HETEROTROPHS = ____________Get energy from consuming other organisms http://www.epa.gov/region5/superfund/ecology/images/fishcartoon.gif

  20. HETEROTROPHS = CONSUMERS HERBIVORES ________________ = eat only plants ________________ = eat only animals ________________ = eat both plants & animals CARNIVORES OMNIVORES http://gallery.hd.org/_exhibits/natural-science/_more2003/_more09/elephant-eating-greenery-in-Addo-Park-Eastern-Cape-South-Africa-2-WL.jpg http://personal.ecu.edu/wuenschk/rabbit-wolf.gif http://www.rodsguide.com/bears/eating.jpg

  21. HETEROTROPHS = CONSUMERS DETRITIVORES ________________ = feed on plant & animal remains EX: mites, earthworms, snails, crabs ________________ = break down and absorb organic matter EX: bacteria & fungi DECOMPOSERS http://montereybayphotos.com/images/nature/2.jpg http://www.fwnp.com/bracket-fungi.htm

  22. Energy flows through an ecosystem in a series of steps in which organisms transfer energy by being eaten CONSUMERS(Heterotrophs) ________________ _________________ = _________________ ↑ ↑ PRODUCERS(Autotrophs) FOOD CHAIN http://fig.cox.miami.edu/Faculty/Dana/foodchain.jpg

  23. Pearson Education Inc, Publishing as Pearson Prentice Hall In most ecosystems feeding relationships are more complex A ______________ links ALL the food chains in an ecosystem together. FOOD WEB

  24. TROPHIC LEVEL Each step in a food chain or web = _______________ ______________ ALWAYS make up the ________ trophic level. PRODUCERS FIRST http://home.insightbb.com/~g.mager/Pond/Ecosystem.htll

  25. Lower levels must be bigger to support the level above. Only about_____ of the energy from each level is passed on. 10% http://home.insightbb.com/~g.mager/Pond/Ecosystem.htll

  26. Some energy is used for life processes such as growth, development, movement, metabolism, transport, and reproduction. The rest is lost as ________ HEAT http://home.insightbb.com/~g.mager/Pond/Ecosystem.htll

  30. SOUTH DAKOTA CORE SCIENCE STANDARDS LIFE SCIENCE:Indicator 3: Analyze how organisms are linked to oneanother and the environment. 9-12.L.3.1. Students are able to identify factors that can cause changes in stability of populations, communities, and ecosystems. • Define populations, communities, ecosystems, niches and symbiotic relationships. • Predict the results of biotic and abiotic interactions. Examples: Dormancy and migration Fluctuation in available resources (water, food, shelter) Biogeochemical cycles Energy flow Cooperation and competition in ecosystems
