Preparing for the Science Gateway

Prewriting - Revisit the prompt & organize ideas from
documents.
Write an essay that explains the
changes involved in the cycling
of matter.
CONCEPT MAP
Describe a food web in detail,
including at least three food
3. Carbon cycle = outside circle
chains.
State the law of conservation
2. Photosynthesis &
of matter and energy and
cellular respir.
explain how this law applies to
photosynthesis and cellular
respiration.
Describe how carbon is cycled
between living organisms and
their environment.

Outlining for Prewriting
• Introduction: Narrative and/or fact
I. EXPLAIN: Food Web
Cycling of matter
• Forest – Producers - grass, shrubs (doc A)
Consumers – deer, herbivores obtain energy from
plants
• Secondary Consumers – hawks, hunters, lions, wolves
eat deer and other rodents to obtain energy;
can not supply own energy
• Consumers – pass away, decompose into soil
-provide nutrients to soil, i.e. bacteria, fungi
-soil used to grow producers

Add your knowledge to the outline/concept map.
Jot into your prewrite everything that you remember about the topic(s)
that will help answer the question. Add in ideas in the appropriate, logical order.
EXPLAIN: Food Web
Cycling of matter
Food chain – transfer of materials (food) & energy (bonds in the food) from one
organism to another.
Forest – Producers - grass, shrubs (doc A) (autotrophs – convert solar energy
w/sun
Sunlight is the source of energy in most ecosystems.
Consumers – deer, herbivores obtain energy from plants
Needs to have 3 organisms in the proper sequence for a food chain
Secondary Consumers – hawks, hunters, lions, wolves eat deer and other rodents
to obtain energy; heterotrophs – must consume others for energy
can not supply own energy
3 levels of consumers Primary (mouse eats plants) Secondary (eat herbivores
(snake) Tertiary eat secondary consumers (owl)
Consumers – pass away, decompose into soil
Organisms obtain energy and transfer it back to the environment when they die.
-provide nutrients to soil, i.e. bacteria, fungi

-soil used to grow producers - DOC A – food chain complete
Outlining for Prewriting
from the documents
II. EXPLAIN/DESCRIBE: Carbon
atmosphere
soil
Carbon cycle -- carbon in the soil fossilizes
Nonrenewable resources for civilization
Fuel is burned --- energy released --- carbon back
to atmosphere
Carbon returns to atmosphere through
plants/consumers
--Byproduct of respiration (Docs B & C)
6
Add your knowledge to the outline/concept map.
Jot into your prewrite everything that you remember about the topic(s)
that will help answer the question. Add in ideas in the appropriate, logical order.
EXPLAIN/DESCRIBE: Carbon
photosynthesis and create energy
atmosphere used by plants to conduct
soil herbivores eat plants to receive
carbon atoms
Carbon cycle -- carbon in the soil fossilizes
Nonrenewable resources for civilization
Fuel is burned --- energy released --- carbon back to atmosphere burning of fossil
fuels releases carbon into atmosphere
Carbon returns to atmosphere through plants/consumers – animals exhale and
release carbon dioxide into the atmosphere
--Byproduct of respiration (Docs B & C)
Cycle – animal dies and decays into soil, plants grown in soil, herbivores eat plants
(get carbon), carnivores eat animals, (both exhale to release carbons), both die and
go back into the soil 7
State :
Law of conservation of matter and energy =
matter and energy can neither be created or
destroyed
Explain how this law applies to
photosynthesis /energy cycle carbon dioxide
cycles to produce oxygen Doc C formula
cellular respiration/ consumers & producers
convert energy into usable forms Formula Doc
C

Add your knowledge to the outline/concept map
Jot into your prewrite everything that you remember about the topic(s) that will help
answer the question. Add in ideas in the appropriate, logical order.
State :
Law of conservation of matter and energy = matter and energy can neither be
created or destroyed
Matter is constantly being recycled, remains constant.
Energy is not recycled but transformed – light to heat or chemical See chemical
equations Doc C
Explain how this law applies to photosynthesis /energy cycle carbon dioxide cycles
to produce oxygen Doc C formula
Reverse of C.R. CO2 and H2O combine in sun to produce glucose and release
oxygen.
cellular respiration/ consumers & producers convert energy into usable forms
Formula Doc C
Useable form of energy is used by cells to make all cellular reactions happen.

We will take a look at what
constitutes a good paragraph
utilizing the details in the prewrite.
