Organism - answer -A living thing
Population - answer -A group of interbreeding organisms
coexisting together (limited by time and location)
Natural boundary - answer -Mountains, rivers, oceans, etc
Artificial boundary - answer -mowed grass, man-made structures
Community - answer -different species within an area and the
interactions within and among these species
,2 | Page
Heterospecifics - answer -members of different species
Ecosystem - answer -All the biotic components in an area with the
abiotic components
Biome - answer -Large areas of land with similar climate, flora
(plants), and fauna (animals)
Biosphere - answer -All of the parts of earth inhabited by life
Biotic - answer -living things
Abiotic - answer -Non-living things (gases, liquids, minerals,
energy)

Optimal zone - answer -zone where a stable healthy population
survives and reproduces
Zone of stress - answer -zone where small numbers can survive
these difficult conditions, they focus on surviving
Zone of intolerance - answer -zone where organisms cannot
survive
Biogeography - answer -study of the distribution of organisms
around the world
Endemic species - answer -species that are native to and found
only within a limited area
Hadley Cell - answer -Convection Currents that cycle between the
equator, 30 degrees North and South.

Ferrel Cell - answer -Cell that moves air form 30 degrees to 60
degrees latitude
Polar cell - answer -Cells of air circulation occurring between 60
degrees north and south and each pole.
Coriolis effect - answer -The effect of Earth's rotation on the
direction of winds and currents. (EWE)
nutrient cycling - answer -The circulation of chemicals necessary
for life, from the environment (mostly from soil and water) through
organisms and back to the environment.
Thermocline - answer -a steep temperature gradient in a body of
water such as a lake, marked by a layer above and below which
the water is at different temperatures.
