EQ: How does
energy from
the sun move
through an
ecosystem?
Energy Flow
and
Food Webs
What are Producers?
→ Organisms that can make glucose through
the process of photosynthesis (plants).
Radiant
Energy
(through the
cholorophyll)
Carbon
Dioxide
(through the
stomata)
Oxygen
Glucose
(Sugar)
What is
Photosynthesis?
→ the process by which
Water
(from the roots)
producers use sunlight to
synthesize glucose from
carbon dioxide and water.
→ Occurs inside the chloroplasts
inside the cells of the leaves.
→ Chlorophyll inside the leaves
is the pigment that absorbs the
sunlight.
Chloroplast
Chlorophyll
Importance?
→ Most of the oxygen in the
atmosphere comes from plants.
Living, breathing organisms must
have oxygen.
→ Photosynthesis provides energy
for living organisms. Living
organisms must have energy.
What is a Consumer?
→ any organism that cannot
make it’s own food for energy.
What are Primary Consumers?
→ leftover stored energy made during photosynthesis
flows from producers to the organisms that eat them.
→ herbivores (plant eaters) or omnivores (meat and
plant eaters).
→ some energy is lost as heat.
What are Secondary Consumers?
→ leftover stored energy from primary consumers is
available for the secondary consumers that eat them.
→ carnivores (meat eaters) or omnivores.
→ some energy is lost as heat.
What are
Tertiary
Consumers?
→ leftover stored energy
from secondary
consumers is available
for the consumers that
eat them.
→ carnivore or omnivore
→ some energy is lost as
heat.
What are Scavengers?
→ consumers that eat
other consumers that
are already dead.
What are Decomposers?
→ organisms that
breakdown dead or
decaying organisms.
What is a food chain?
→ the transfer of energy from the sun to
producer to primary consumer, to
secondary consumer, to tertiary consumer.
→ this is energy flow in an ecosystem.
What are food webs?
→ interconnected food
chains that show the
feeding relationships in
an ecosystem.
What are Food Pyramids?
→ show the amount of
energy available at
each energy source
level (trophic level).
→ show how much
energy is needed to
support that the next
trophic level.
What are
organic
compounds?
→ matter that is made of
mixtures of CARBON and
other elements like sulfur,
hydrogen, oxygen,
phosphorous, and
nitrogen.
