, METABOLISM : ENERGY AND ENZYMES
metabolic activities and
alls need constant
supply of energy to
carry
out
maintain structural
organization
about
energy-ability to do work or
bring a
change
of life
(growth ,
reproduction)
all
general characteristics , development ,
metabolism ,
require energy
produces produce nutrients
photosynthesizing organic

most life depends on solar
energy

stored in chemical bonds , can be converted to kinetic
energy
↳
food is form of chemical
energy
When animal moves chemical is converted to mechanical
energy (type of

flows
biological systems energy
in
plants capture small portion of solar much of it is lost as heat
energy
on
and then food produce
when
they photosynthesize use the
they ,
more
energy
lost as heat
gets
energy eventually
all captured solar is lost as heat as
organisms metabolize
nutrients flows does not cycle

energy
cannot be or
destroyed ,
but can
change from one to other
