Niche correct answers environmental conditions that allow a species to persist in a given
environment along with the per-capita effects of that species on the environmental conditions.
Fundamental niche correct answers describes where species could occur, if there was no
competition and predation. This is often limited to abiotic factors.
Realized niche correct answers describes where a species does occur, and includes biotic
interaction with other species (e.g., competition and predation).
Niche "role" correct answers The idea was originally discussed with the analogy of a village as a
community. Each person in that village, such as the local vicar has a job or relationships in the
village, must like a badger in the forest.
Niche "needs" correct answers resources or factors necessary for the existence of a species in a
given habitat.
Turnover correct answers In the fall, air temperatures cool, causing the surface water in a lake to
cool and become more dense. This water sinks, forcing lighter, less dense water to the surface.
This continues until the whole lake is about 4 degrees -- eventually the top water gets colder than
4 degrees, now floats, and freezes. A similar process occurs in the spring. The sinking action and
mixing of the water results in the exchange of bottom and surface water, moving important
nutrients in the water column.
Adiabatic cooling correct answers heating or cooling that comes from within. Air moving up
loses pressure (at higher altitude) and hence loses heat (cools) and vice-versa.
Dew point correct answers temperature at which condensation begins
Rain shadows correct answers where winds push air over a mountain. As the air rises, it cools
(adiabatic cooling) and loses its ability to hold water, causing rain. The air that reaches the other
side is now dry, causing a dry "shadow" on the far side.
Hadley cells correct answers near the equator go up as high as 20 km. The next cells, from 30 to
60 degrees latitude, are lower and have less power
Doldrums correct answers stillness of the rising (and not blowing) air usually located between 5°
north and 5° south of the equator
Horse latitudes correct answers Between about 30° to 35° north and 30° to 35° south of the
equator. This region of subsiding dry air and high pressure also results in weak winds.
Biomes correct answers large-scale patterns of temperature and rainfall to define broad land
based vegetation types
