Ecosystems & Energy Flow http://www.youtube.com/watch?v=cADgZqts9mM The Big Ideas: Everything is Interconnected INTERDEPENDENCE “Circle of Life” Stuff Doesn’t Disappear (or appear) Again: NOTHING can come from nothing or become nothing No Magic here, folks Your “Environmental Stuff” ` www.wordle.net Ecology The study of the interactions of living organisms with one another and with their physical environment Ecosystem • Group of _____________ interacting with each other and their ______________. • Organisms: Living Things! • Like Plants, Animals, Microbes, etc. • Physical Environment: Non-Living Things! • Like Soil, Water, Sunlight, etc. Parts of an Ecosystem Population: a group of individuals of the same species in an area Habitat: the place where a particular ___________ of a species lives ___________ :all of the species that live together in a habitat Abiotic Factors: the physical aspects of a habitat Biotic Factors: the living _________ in a habitat Think about the Lion King Ecosystem: The African Savannah Includes all of the biotic factors: species’ populations (like the lions, giraffes, antelope, trees, etc.) And all of the abiotic factors: pride rock, the water hole, the land, etc. Species/Population: The Lions/ The Pride Habitat: The Pridelands This little part of the whole Savannah Community: all of the species together Roles within an Ecosystem Producer: an organism that produces its own food using energy from light or other chemical reactions PLANTS, some bacteria, algae PHOTOSYNTHESIS Roles within an Ecosystem Consumer: an organism that gets its energy from eating other organisms Two Types of Consumers: Primary Consumers: eat producers AKA: Herbivores! Secondary Consumers: eat other consumers AKA: Omnivores and Carnivores Decomposer: an organism that get energy from breaking down dead organisms Ahem, an Extra Credit Opportunity is calling you! Pick an extinct or endangered organism Tell its story- Picture, Paragraph or Two of Information Basic Facts Habitat Interactions with other species (including humans) Why it’s endangered/extinct Other interesting information This website might be a good place to start: http://www.iucnredlist.org/
