community
group of populations in the same area
population
group of individuals of same species in same area
biotic factors
behaviors and interactions with other species
abiotic factors
nonliving, chemical and physical components
climate
temperature, precipitation, sunlight, and wind in an area
biome
a major type of ecosystem
photic zone
upper part of aquatic biome, sufficient light for photosynthesis
aphotic zone
below photic zone of an aquatic biome, not much light
benthic zone
bottom aquatic biome, made of sand and inorganic sediments
detritus
dead organic matter, source of food
thermoclines
narrow layers of abrupt temperature change in an aquatic biome
littoral zone
shallow, well-lit area close to shore in an aquatic biome
limnetic zone
aquatic biome, water too deep to support rooted plants
oligotrophic lakes
nutrient-poor and oxygen rich
eutrophic lakes
nutrient-rich and oxygen deficient
wetland
habitat inundaned by water at least some of the time
hydrophytes
plants dependent on water-rich soil
estuaries
transition area between river and sea
intertidal zone
part of marine biome periodically submerged by tides, rocky
pelagic zone
part or marine biome with vast realm of open water, very abundant
tropical rainforest
biome by equator, needs heat and rain, lots of plants/animals
savanna
biome of grassland with some tries, lots of grazers
desert
biome with hot, dry climate; CAM plants, leaves with just backbends
grassland
biome of rolling grassland, no trees, regular fires
chaparral
biome of high foliage area, different terrain, dependent on fires
deciduous forest
biome with tree forests that are temperate (loose leaves in winter)
taiga
biome of a pine-tree forest
tundra
biome that is frozen/half-frozen all year
