About This Presentation

Life itself is but a temporary condition purchased at the cost of a continuous expenditure of energy


Slide Content

By Prof. Liwayway Memije-Cruz
Thermodynamics in Ecology

Energy and how it is
handled and used by
living organisms.

The Sun
The sun is the
driving force of
photosynthesis
which is the most
important
chemical reaction
of all the
chemical
reactions.

Food Energy Chain

Food Web

Energy input in an Ecosystem

Thermodynamics
the branch of physics involved
with studies on the effects of
changes in temperature,
pressure, and volume on
physical systems at the
macroscopic scale.
The motions produced by the
particles produce heat. Heat in
thermodynamics means "energy
in transit" and dynamics relates
to "movement" Based on the said
principle, thermodynamics
studies the movement of energy
and how energy instills
movement.

First Law of Thermodynamics: “Energy
cannot be created or destroyed, only
converted from one form to another”
.

Entrophy
the degree of disorder or uncertainty in a system

Second Law of Thermodynamics
it adds on a
statement about
entropy and how
all energy
conversions are
less than perfect.
The result is loss
of energy –
typically in the
form of heat.

Life itself is but a temporary
condition purchased at the cost of a
continuous expenditure of energy.
