R- react to environment
R- reproduce
R- regulate body temp
E- eats
what happens to the vast majority of the energy the earth’s surface absorbs from the sun?
the surface radiates it to the atmosphere, which is absorbed
if you can make your own food using light energy, you are a …
producer
a single organism of a particular species
individual
how do you know if two organisms
are from the same species?
they can breed w/ eachother , have healthy babies, and the babies can also have kids
the total number of individuals of a species found in a particular area that interact with each other
population
if you eat other organisms to get your energy you are a…
consumer (primary or secondary)
what is energy balance
the energy radiated to earth=the energy radiated away from earth
all of the world’s ecosystems
biosphere

of living things within an area that

true or false: ice and snow reflect
true
true or false: rock and dirt absorb
true
what is sublimation
ice or snow evaporating rapidly when super dry air hits it; doesn’t go through the liquid phase, goes straight to vapor
what is deposition
water vapor turns directly into ice;opposite of sublimation
what is a density-independent factor
a factor that doesn’t rely on the density of the organism as to how the factor affects the organism
what is a density-dependent factor
a factor that does rely on the density of the organism as to how the factor affects the organism
true or false: a forest fire is a density-dependent factor
false
true or false: food scarcity is a density-dependent factor
true
true or false: disease is a density-independent factor
true
