Previous Knowledge:
Stu&ents 'oul& $ae no'le&ge o* '$at ecology is
an& t$e biotic an& abiotic *actors t$at

&e*initions o* t$e terms$abitat,population, community,
ecosystem, pro&ucers, consumer, $erbiore, carniore,scaenger,
parasite, prey, pre&ator an& &ecomposer+ Stu&ents
can also explain t$e terms
pro&ucers, consumer an& trop$ic leel in terms o*
*oo& c$ains an& *oo& 'ebs+ T$ey can
&escribe t$e cyclical nature o* nutrient *lo' an& t$e
noncyclical nature o* energy *lo'+T$e 'ee be*ore, t$ey learnt to
&escribe an& interpret pyrami&s o* numbers, biomass

ma&e up o* processes by '$ic$
carbon &ioxi&e is remoe& *rom an& restore&
to t$e enironment+
Specific Instructional Obectives:
By t$e en& o* t$e lesson, stu&ents s$oul& be able
to:
1+ escribe $o' carbon is recycle& 'it$in an ecosystem+
-+ Explain '$y t$e carbon cycle is important in our
