Chapter 4 - Ecosystems The Nature of Ecology The Earth's Life-Support Systems Ecosystem Components Energy Flow in Ecosystems Primary Productivity of Ecosystems Soils Matter Cycling in Ecosystems How Do Ecologists Learn About Ecosystems?
Back to Bio: A Crap-ton of Definitions - Welcome to your Sophomore Year - back to memorization Admit it, you've all misspelled it - organisms Not to be confused with that-thing-you-lacked-in-high-school - populations - "Totally Spherical, Dude" - interactions in ecosystems - Energy Sources - it doesn't just come from CMP - Energy Movement - it moves through an ecosystem like taco bell. "C'mon, now they're just making up prefixes!" - the biogeochemical cycles Big Fish eat Little Fish - food webs & trophic levels & energy movement - Diversity - Not just important in your college decision - The Dirt on Dirt - your 411 on all things earthy ( Acronym: Oh, the ABC's in Bed)

Limiting Factor Principle Too much or too little of any abiotic factor can limit or prevent growth of a population, even if all other factors are at optimum levels. http://www.marietta.edu/~biol/102/ecycle.gif
Chapter 5 - Evolution & Biodiversity Origins of Life Evolution & Adaptation Ecological Niches & Adaptation Speciation, Extinction & Biodiversity What is the Future of Evolution? https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQqH6fIsJTKdLSdvBDRgcu8VzOkjG0o6xYxJwXOUNLgARRki5JxHA
The Land Before Time: Everything is Dead Now - Past, Schmast - what's so great about it anyways? - Evolution and Genetics - you'll feel like a genius after this. "Microwaves, right? No, wait, I swear it started with 'Micro', right?" - micro/macroevolution Last to be picked for every dodgeball team - natural selection Cooperation, but aggressive cooperation - coevolution - I Still Don't Know How to Pronounce Niche - nitch? nesh? quiche? - Change Is Good - how speciation and extinction lead to biodiversity. "You two behave, or I'll separate you!" - speciation Just like zombies, some things are better off left dead - extinction - The fuuuuuuuuture! - has science finally gone too far? probs.
Chapter 6 - Climate & Terrestrial Biodiversity Weather: A Brief Introduction Climate: A Brief Introduction Biomes: Climate and Life on Land Desert Biomes Grassland, Tundra and Chaparral Biomes Forest Biomes Mountain Biomes
The Local Weatherman & Travel Agent: Biomes - It's Raining, It's Pouring - this presentation's got me snoring. I'm walking on sunshine - weather Peer pressure - atmospheric pressure systems - Long-Term Relationship - climate & you 4EVA <3 Bad Influence - what influences climate Surf's Up! - oceans It's a gas-tastrophe! - atmosphere gases Candy mountain, Charlie! - topography - There is no pun for Biome - it's like orange, nothing rhymes with it. A horse with no name - desert biomes "We're not in Kansas anymore, Toto!" - grassland biomes Make like a tree and leaf - forest biomes Take a hike - mountain biomes
