A | B |
climate | average conditions over a long period of time in a given area |
weather | day-to-day conditions in Earth's atmosphere |
climatographs | climate diagrams that show temperature and precipitation |
gross primary production | the rate at which primary producers carry out photosynthesis |
net primary production | the organic matter or biomass that remains after cellular respiration |
canopy | tall trees form a dense covering in the rainforest |
emergent layer | highest layer of the rainforest |
understory | lowest layer of the rainforest; plants have large, flat leaves |
epiphytes | plants that grow on other plants instead of soil |
tropical dry forest | biome that is warm year-round, but has highly seasonal rainfall |
deciduous trees | lose their leaves and stop photosynthesizing during part of the year |
estivation | deep, sleep-like period of dormancy to avoid dry periods |
savanna | tropical region with less rainfall than tropical dry forests but more rainfall than deserts |
desert | biome that receives under 25 cm of rain each year |
succulents | plants with a thick, waxy cuticle that store water in their tissues |
temperate rainforests | biome w/ heavy rainfall and year-round moderate temperatures. Ex: Oregon |
coniferous trees | trees that produce seed-bearing cones |
temperate forest | Example: Northeastern US |
temperate grassland | aka prairie; ex: Midwestern US |
Chaparral | biome w/ warm, dry summers; mild, wet winters |
long body appendages | adaptation that helps keep animals cool |
boreal forest | aka taiga; long, cold winters and short, cool summers |
tundra | cold desert |
permafrost | underground soil that is frozen year-round |
polar ice | not a biome since it is not technically on land |
mountains | landform that could be home to many biomes due to changes in elevation |
salinity | amount of salt in a body of water |
brackish | less salt than ocean but more than freshwater |
photic zone | light can penetrate through water; photosynthesis occurs |
aphotic zone | no light penetrates |
benthic zone | bottom of a body of water |
littoral zone | shallow, near-shore portion of photic zone in a pond or lake |
limnetic zone | farther from shore, no rooted plants w/in this area of a lake or pond |
wetlands | any area of land that is covered in water at least part of the year |
marsh | grassy wetland |
swamp | wetland w/ woody shrubs and trees |
bog | wetland with low nutrients, stagnant water, and peat on top |
fen | similar to bog, but w/ a connection to groundwater; less acidic and stinky |
rivers and streams | moving bodies of fresh water |
flood plain | area near a river that floods periodically |
estuary | where a river meets the ocean; usually brackish |
world ocean | all of the oceans connected |
currents | horizontal movements of ocean waters |
tide | how far the ocean reaches up on a shoreline based on gravitational pull of moon and sun |
upwelling | vertical flow of cold, nutrient-rich water toward teh surface |
downwelling | when two currents pull away from each other and water flows downward |
intertidal zone | organisms here must be tolerant to huge changes in temp and salinity |
neritic zone | zone from low-tide to end of continental shelf; kelp forests and coral reefs here |
open ocean zone | zone that is not very productive; very dark, few organisms live here |
euglena | protists that can be heterotrophic or autotrophic |
paramecium | moves w/ cilia |
amoeba | moves with a pseudopod |
flagella | long, whip-like tail |
cilia | short, beating extentions |
gonads | reproductive organs |
echinodermata | means "spiny skin" |
