2.2 FLOW of ENERGY in an ECOSYSTEM
WHAT YOU WILL LEARN
-the flow of energy through an ecosystem
-the energy source for PHOTOSYNTHETIC
producers
-the differences between food chains, food webs, and
pyramid models
READING Q’s
DEFINE: Energy
- the ability to cause change; energy cannot be created or
destroyed-only transferred
READING Q’s
IDENTIFY:
How do AUTOTROPHS obtain energy?
-from sunlight or inorganic substances
READING Q’s
IDENTIFY:
How do HETEROTROPHS obtain energy?
-by consuming other organisms
READING Q’s
DRAW: a circle around the autotroph/box around the
heterotrophs.
READING Q’s
4-IDENTIFY the # of:
1
-producer ___
1
-carnivore ___
1
-omnivore ___
1
-herbivore ___
READING Q’s
COMPARE & CONTRAST a DETRITIVORE/DECOMPOSER
DETRITIVORE
-EAT fragments of dead matter in Ecosystem
-Includes worms & aquatic insects
BOTH
-Break down dead matter
-Both get energy from dead organic matter
DECOMPOSER
-BREAKDOWN dead organisms by releasing ENZYMES
-Include BACTERIA & FUNGI
READING Q’s
EXPLAIN:
What does a trophic level represent?
-a step in a food web or food chain
READING Q’s
COMPARE & CONTRAST a FOOD CHAIN/FOOD WEB
FOOD CHAIN
-simplified model representing the transfer of energy from
organism to organism
BOTH
-show energy flow from one organism to another
FOOD WEB
-model representing the many interconnected food chains
& pathways in which energy flows through group of
organisms
READING Q’s
EXPLAIN: what does an arrow [] signify in a food
chain/web?
-represents one way energy flow
-typically starts with AUTOTROPHS and moves to
HETEROTROPHS
READING Q’s
IDENTIFY what ecologists use to model how energy flows
through an ecosystem:
-Ecological Pyramids
APPLICATION NOTES
-As a COLLABORATIVE group complete the NOTES using
your knowledge from the reading.
