what is a biome?
biomes are major divisions of terrestrial environment
how are biomes distinguished?
by their predominant plants are particular climates
what is the definition of ecology?
The interrelationships of organisms and their environment
who coined the term "ecology" ?
why is the word "interrelationships" important in defining ecology?
because no organism exists entirely independently from it's enviorment and other organisms. all organisms and environments are interralated on some level therefore it's critical to include this truth in the definition.
list all levels of ecology from largest to smallest?
what are the four major divisions of ecology that are studied?
what is organism ecology?
Study of adaptations: food, heat conservation, periodicity, etc.
what is the old term for organism ecology that is now used for population ecology?
what is population ecology?
Interbreeding groups of the same species
what is population ecology AKA?
what is community ecology?
[AKA synecology]
– All populations in a given area
– Often study of relationships to environmental factors
what is ecosystem ecology?
– Community plus the non-living environment
– Energy flow, mineral cycling
what are some important services provided by natural ecosystems?
- water, oxygen, food, wood, fertilizers, agriculture
list the taxa between kingdom and species
What divisions are used in a scientific name? How is a scientific name differentiated from the rest of the text in
a paragraph?
8. Explain how this quotation
family endings:
animals end in -idae
plants end in - acae

scientific names= genus and specific epithet and are italicized!
Explain how this quotation from Darwin’s On the Origin of Species relates to our definition of ecology: “Look
at a plant in the midst of its range. Why does it not double in numbers? . . .To give the plant increasing numbers,
we should have to give it some advantage over its competitors or the animals that prey upon it.”
because all organisms do not live in an exclusive environment. They're all interconnected and effect one another in one way or another.
what are Solstices?
(in summer and winter) the longest and shortest days of the year
what are Equinoxes?
(Autumnal and Vernal):days on which there are 12 hrs of sunlight and 12 hrs of darkness
where are true "rainy seasons" restricted to?
the tropics
where do very heavy rains tend to occur?
solar equator
Intertropical convergence references what?
rainy seasons (direct sunlight = great evaporation = heavy rain)
what is a result of the equator passing the sun twice?
2 rainy seasons!
what is the lattitude of a region located on the equator?
0 degrees = tropics
if an area is warmer what implications are usually true?
warmer= more evaporation = more rain
what direction does the earth rotate?
west to east
what wind is observed between 0-30 degrees lat?
the northeast and southeast trade winds
what winds are observed between 30-60 degrees?
the westerlies
what winds are observed at high latitudes?
the polar easterlies
what is Hadley cell wind?
Air cools at high altitudes, becoming more dense, so it begins to sink back to the Earth, in a belt
around the globe at 30 N & S. Remember that this air has lost much of its moisture.
Polar cell ...
results from relatively warm air rising at 60 and falls near poles— polar winds
Ferrel cell....
cell is pulled into motion by the other two and acts like a ball bearing from 30–60
what is the coriolis effect?
Due to the rotation of the earth wind (and water) currents are deflected to the right (clockwise) in the Northern
Hemisphere and to the left (counter clockwise) in the Southern Hemisphere.
what occurs during el nino events?
the winds that usually push warm water west along the equator fail so warm water stays east so floods occur from peru to california and australia and indonesia have droughts.
