The Flow of Matter and Energy

Levels of organization Biosphere Biome Ecosystem Community Population Organism or Individual

Energy Transfer Chemical elements that make up the molecules of living things pass through food webs and are combined and recombined in different ways Energy is stored in newly made structures, but much is released as heat Continual input of energy from sunlight keeps the process going

Energy Flow Trophic levels Autotroph = “self – energy” Heterotroph = Organism’s relative position in a sequence of energy transfers Autotroph = “self – energy” Heterotroph = “different – energy” http://ocw.tufts.edu/data/5/241030/72027_medium.jpg

Producers Autotrophs Photosynthetic Some bacteria are chemosynthetic Terrestrial : Plants; Aquatic : Protists and Bacteria http://city.waverlyia.com/docs/Green%20Trees.jpg http://www.fiu.edu/~reink/plima.jpg http://library.thinkquest.org/10952/students/2-truc/ALGAE.GIF

Consumers Heterotrophs Decomposers Herbivores, carnivores, omnivores, detritivores, decomposers Decomposers specific term for some bacteria and fungi Make nutrients available again to autotrophs, recycling chemical nutrients http://discover.edventures.com/images/ http://www.african-safari-pictures.com/image-files/vulture-pictures.jpg

Ecosystem Components Living things – biotic factors All plants, animals, fungi, bacteria, protists Non-living things – abiotic factors Air, water, rocks, sunlight, etc. Next, classify the objects in the following diagram as biotic or abiotic

Food Chains http://www.blog.thesietch.org/wp-content/uploads/2007/04/energytransfer2.thumbnail.gif http://www.greenfacts.org/images/glossary/trophic-level1.jpg

Food Webs http://www.cals.ncsu.edu/course/ent425/tutorial/foodweb.gif http://nasadaacs.eos.nasa.gov/articles/images/2005_fish_web.jpg

The Energy Cycle Amount of life in any environment is limited by the available energy, water, oxygen, minerals and recycling of dead organic material Humans often change the flow and reduce land fertility…in what way? When there are too many organisms for decomposers to recycle, fossils fuels are created Burning of fossil fuels introduces stored energy as heat and released large amounts of carbon dioxide disrupting the cycle
