13. About 90% of mass and energy
(these are fairly interchangeable when discussing trophic
levels and biosphere) is lost in going from one trophic
level to the next
one above it. When we eat "low on the food chain" we will end up with
about 10% of the mass/energy, whereas if we raised rabbits on the same grain,
they would end of with about 10% of the mass/energy, and then we would end up
with 10% of the rabbits mass/energy when we ate them, i.e., we would end up
with only 1% of the original grain's mass/energy!!
14. see classnotes link for Feb. 15 and 17 lectures (ie, latent heat, specific heat, cohesion, adhesion, ability
to dissolve different substances, etc).
15. TH circulation is the
"global oceanic conveyor belt". It transports heat and salt in an
attempt to even out their abundance around the world ocean. Currently, TH circulation is largely driven
by deep-water formation in the N. Atlantic near Greenland, where high density
cold, saline water sinks and begins a journey around the world ocean flowing as
a bottom current and then returning as a near-surface warm current. Any event that stops or slows deep- water
formation will slow TH-circulation and thereby slow the return flow of surface
warm water to the N. Atlantic. This
happened during the Younger Dryas as the ice sheets
melted.
16. Biotic components are mainly the
plants and animals (living organisms), whereas the abiotic
components are water, climate, nutrients (largely from soils, but also from
atmosphere), and energy (from sun)
