Key Question for Food Webs: Why aren’t humans and tigers at
the “top of the food chain?”
Objectives and StandardsObjectives• C: Take all notes for food webs and draw a food web• L: Fill in the blanks on notes, write cue words, write
summary
• Standards:– II.I.I.1. Explain how matter is transferred from one organism to another and between organisms and their environment (e.g., consumption,
the water cycle, the carbon cycle, the nitrogen cycle).– II.I.I.2. Know that the total amount of matter (mass) remains constant although its form, location, and properties may change (e.g., matter in
the food web).– II.II.I.1 Identify how living and nonliving parts of an ecosystem and the relationship among these components.– II.III.I.2. Explain how energy from the sun supports life on Earth
I. Ecosystems are made of biotic and abiotic factors
A. Biotic—grass, moss, fungi, bacteria, deerB. Abiotic—rocks, sunlight, clouds, water, air

II. Energy flows through food webs, starting at the sun
A. Producers are organisms that make their own food using energy from the sun.1. Examples: ferns, moss, trees, roses, orange trees

B. Consumers eat other organisms to get energy
1. Predators kill and eat prey.2. Parasites “steal” food from
another organism without killing it.

C. Decomposers break down wastes or remains or organisms
1. Bacteria and fungi release materials to the air, water, and soil.

1. Bacteria and fungi release materials to the air, water, and soil.
2. Energy can flow from consumers or producers to decomposers
3. Decomposers (usually) don’t pass energy on to other organisms.

3. Decomposers (usually) don’t pass energy on to other organisms.
D. Eventually, all energy is converted to heat!
III. Organisms can interact with each other in several waysA. Predators can eat prey
(+/-)B. Parasites can get food
from an organism without killing it (+/-)

Summary: Example Food Web
Arrows show the flow of energy.
Where does energy come from? (not on this food web).
Draw energy flowing through a food web. Label (1) the sun, (2) Producers, (3)
Consumers, (4) Decomposers

Note: “Calories measure heat energy”1. Give an example of a consumer2. Give an example of a producer3. Where does our energy come from?4. What organisms decompose things when
they die?5. What does a predator eat?6. What substance allows plants to make food
using sunlight?

Entering the Classroom
• Get your binder and make sure you have a sharp pencil
• Get out your packet that says: – Food Webs, Cycles, Biomes
• Get out your study guide for Food Web CBM and review for your CBM for 5 minutes (you may quietly talk with people around you).

• Everyone needs a sharp pencil and a piece of paper.
FREEWRITE!
“Carbon is an element. Each atom of Carbon has 6 protons, 6 neutrons, and 6 electrons. One Carbon atom combines with two Oxygen atoms to create Carbon Dioxide. Sugars, proteins, and fats all contain carbon atoms. Much of the food we eat is made of carbon.”
•Where do you think the carbon goes after we eat it? •Do you think the Earth will ever run out of Carbon
FREEWRITES are continued writing. You must constantly write during the time allotted. If you have already answered the question, please make connections with other parts of the question or write about something related.

Nitrogen Fixation
• Nitrogen Fixation is the process used by bacteria that changes nitrogen from a gas into a form plants can use (NO3)
Rhizobium trifolii
Denitrification• Process that returns nitrogen to the atmosphere
Respiration
• Respiration is the process that uses oxygen and returns carbon (carbon dioxide) to the atmosphere.

Evaporation
• Evaporation is changing from liquid to gas
Condensation
• Condensation is changing from gas to liquid
Precipitation
• Precipitation is water falling to the earth in any form (rain, sleet, etc).

destroyed• L: Write notes (fill in the blank), cue words,
and a summary

Question: How much Carbon was on the earth when Dinosaurs roamed?
A. In the Water Cycle, water moves between the atmosphere and the earth—the water on the earth is the same water that was here when the earth was formed. (Note: this means the “same amount”)
1. Evaporation moves water from lakes, streams, oceans, and other bodies of water into the air.
2. Condensation forms clouds.
3. Precipitation is when water falls to the earth as rain, sleet, or snow.

Water Cycle
B. In the Carbon Cycle, carbon moves between earth, living things, and the atmosphere.
B. Carbon Cycle1. Photosynthesis moves carbon from the atmosphere (CO2) to living things (Carbon is converted from CO2 into sugar)
2. Animals and other organisms eat plants, taking in carbon.
B. Carbon Cycle3. Respiration, Decomposition, and burning fossil fuels returns CO2 to the atmosphere.
What’s a fossil fuel?
C. In the Nitrogen Cycle, nitrogen moves between earth, living things, and the atmosphere.
C. Nitrogen Cycle1. Most of the Atmosphere
is made of nitrogen (78%), but plants and animals cannot use it in the form of a gas.
2. Nitrogen Fixation is when bacteria change nitrogen from gas into a form that plants can use (NO3)

2. Nitrogen Fixation is when bacteria change nitrogen from gas into a form that plants can use (NO3)
C. Nitrogen Cycle3. Plants get nitrogen from
the soil and animals get nitrogen from eating (either plants or animals).
4. Nitrogen is returned to the atmosphere by excretion (getting rid of wastes) and decomposition a. Denitrification is the
process bacteria use to returns nitrogen to a gas in the atmosphere.
