energy and matter
closed system
earth as far as matter is concerned
open system
earth as far as energy is concerned
glass
unique substance that allows light to enter, but will not allow heat to escape
greenhouse effect
allows light to enter, but not allow heat to escape
light arriving at the surfave
warms the surface, then traps heat (global warming)
CO2
greenhouse gas in the atmosphere; when increased more heat is trapped
plants
producers; only living things that consume energy directly from the sun
sunlight
catalyst for photosynthesis
soil
agent for photosynthesis
photosynthesis equation
6CO2 (carbon dioxide) + 6H2O (water) —(sun)—> C6H12O6 (organic matter) + 6O2 (oxygen)
electromagnetic spectrum
all forms of energy that travel in waves (IMPORTANT ONES: infrared, visible, ultraviolet)
atom
smallest particle
protons
positively charged particles in the nucleus
electrons
negatively charged particles in the nucleus
neutrons
neutral particles everywhere beyond the nucleus
vaccums
energy can travel through empty spaces
air composition
78% nitrogen, 21% oxygen, 0.03% CO2, 0.02% H2O
cell respiration
breaks down complex molecules found in organisms (humans/animals)
cell respiration equation
C6H12O6 + 6O2 ——> 6CO2 + 6H2O + ATP
how to get rid of plastic
burn it (breaks the bonds)
water cycle
precipitation, runoff, groundwater, evaporation, condensation/transpiration
black
absorbs everything
white
reflects everything
why are plants green
they absorb every color except green
food chains/webs
show the flow of energy through living things
10% rule
divide by 10; 90% is LOST
trophic levels
producers - most, consumers, organisms (primary, secondary, apex - fewest), and decomposers
consumers
animals
