webs.
Energy flows through food webs and is lost to heat and
metabolism as it passes through each trophic level. (10%
rule)
Matter is recycled in ecosystems. Carbon, Nitrogen,
Phosphorus.
Populations of organisms grow exponentially if there are no
factors limiting their growth.
Limiting factors such as PREDATION, FOOD
AVAILABILITY, COMPETITION AND DISEASE limit the
size of a population. (constraint)
Resources
 Book: 506-511, 514-515, 518-519, 525-532, 535-536
 Videos: Crash course
 Carbon cycle
 Nitrogen cycle
 Ecosystem ecology
 Population ecology
 Community ecology (a little bit)
 Human population growth
Actions
 REPETITION! – watch small, important, segments of
the videos over and over and over and over and over
and over and over and over and over…………………..
 EXPLAIN OUT LOUD – explain a concept out loud to
someone. DESCRIBE and EXPLAIN important graphs
