carbon cycle
CO2 assimilated by plants through photosynthesis and converted into organic compounds. when plants are eaten or die, carbohydrates are broken down to Co2 and H2O through respiration. releasing CO2 into atmosphere.
what are the major reservoirs
rocks–> sedimentary rocks, fossil fuels. the atmosphere
Greenhouse effect
CO2 traps solar heat into atmosphere
what area experiences more warming
arctic, controbuting to permafrost thawing
respiration
use of oxygen to break down organic compounds to release chemical energy.
an increase in temperature will increaes the
rate of metabolism for microorganisms
different litter composition will
affect rate of soil respiration
in the decomposition process, glucose is
lost by leaching
in the decomposition process, cellulose is
more difficult to decompose
in the decomposition process, lignin is
extremely difficult to decompose and will take a long time
litter with higher C:N as in >:>
will take longer to decompose
terminal bud
a bud is an undeveloped shoot
lateral bud
located above leaf scar
leaf scar
left when leaf fell
stipular scars
sometimes appear under or beside the leaf scars
bud scale scars
represent place where growth began each year
lenticels
spongy areas in the surfaces of stems allow gas exchange to occur across the periderm
catkins
compound flowers or remains of flowers that look like tiny pine cones
