Freshwater
In a pond or lake, the zone that is colder and more dense with dead plankton and heterotrophs
Profundal
Partially enclosed body of water where salt meets freshwater
Estuary
summers are moderately long and dry, soil ranges from sandy and fine-textured to loose rock fragments
semiarid desert
1st species to colonize barren land
pioneer species
more deaths than births, more people leaving than entering
PGR < 0
In a river or stream, the area that is clear and cooler, and has a high oxygen level
source
Zone where temperature decreases with increasing depth. Abundant with seaweed, fish, sponges, and sea anemones
Benthic
Has a surge of life after the rainy season, has a thin layer of humus
savannah grassland
when succession has slowed and the area has reached equilibrium a _________ is established
climax community
Type of factor that depends on the size of the population
Density- Dependent factors
In a pond or lake, the zone that is warmer and shallow and has abundant plant species
Littoral
Zone with hydrothermal vents and specialized fish species
Abyssal
Has permafrost and is cold
Tundra
soil is already there and species return faster due to quicker vegetation appearance
secondary succession
Exponential growth has this type of growth curve
j shaped
In a stream or river, the area that is murky and has a lower oxygen level
mouth
Zone that is constantly changing, can be rocky or sandy
Intertidal
Soil is nutrient poor and most nutrients are found in the vegetation. Precipitation is evenly distributed year-round
Tropical Rain Forest
organisms live in an unstable environment, small bodies, reproduce quickly
rapid life history patter, r- strategy
Soil is fine-textured with a moderate salt content
Coastal desert
Zone/Area that is well lighted and fish/plankton are abundant
Limnetic Zone
Zone that is cool with thermal zones.
Pelagic
Winters are cold and long, summers are short cool, growing season is short (less than 3 months)
Taiga
The most common type of density dispersion factor
clumped
soil is fertile due to decaying leaf litter, has well-defined seasons with a distinct winter
temperate forest
