- desert
- hot and dry, a large area of land that has very little water and very few plants growing on it
- tropical rain forest
- it's where Tukan Sam lives from fruit loops
- savanna
- a grassland that has scattered clumps of trees and sesonal rains
- food chains vs. food webs
- food chain just shows one line of eating, food web shows a lot more things being eaten and what they eat
- taiga
- same as deciduous forest, nearly continuous belt of evergreen conferous forests across the northern hemisphere, in the north america and eurasia
- Biomes
- there's at least 7 of them, climates where populations of many different species live
- Nitrogen Cycle
- the biogeochemical cycle that describes the transformations of nitrogen and nitrogen-containing compounds in nature. It is a gaseous cycle. [http://en.wikipedia.org/wiki/Nitrogen_cycle], the circulation of nitrogen
- Omnivore

- Decomposers
- break down all dead stuff
- Predator/Prey relasionships
- predator eats prey
- producer
- autotrophs [manufacture own food], photoautotrophs [use the sun's energy to produce food], chemoautotrophs [use chemicals to produce food]
- water cycle
- The earth has a limited amount of water. That water keeps going around and around and around and around and in what we call the "_____________".... This cycle is made up of a few main parts:...evaporation (and transpiration), condensation, precipitation, and collection.
- Carbon cycle
- people give off carbon dioxide, plants take it in and produce oxygen, then we breathe that in... bam, that's the cycle
- tundra
- cold and stuff, a treeless Artic region where the subsoil is permanently frozen
- Consumers
- first order [a mouse eats some grass], second order [a snake eats the mouse], etc..
- Trophic levels
- the levels on an energy pyramid
- Symbiosis
- parasitism [one organism benefits, while the other looses something], commensalism [one organism benefits, and nothing happens to the other], mutualism [both organisms benefit from the interaction]
- pyramids
- producers are at the bottom of these....
- temperate grasslands
- more grass, limited trees streams and lots of herbavores
- Herbivore
- any animal that feeds chiefly on grass and other plants
- energy transfers
- energy is lost as heat on the way up the pyramid
- consumers: primary vs. secondary
- secondary must eat more than the primary to gain the same amount of E, because E is lost as heat
- Carnivore
- any animal that feeds on flesh
