Entering the Classroom

• Get your binder and make sure you have a sharp pencil

• Get out your packet that says: – Food Webs, Cycles, Biomes

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

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.

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.

C. Decomposers break down wastes or remains or organisms

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.

2. Energy can flow from consumers or producers to decomposers

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?

Closing:




• 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).

CBM (you have 15-20 minutes)

• 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.

Above all, keep writing.

This first one will be short—about 2-3 minutes.

Key Question for CyclesWhen have you eaten a part of a dinosaur from 210 million years ago?

Objectives and StandardsObjectives• C: Define: Nitrogen Fixation, Denitrification,

Evaporation, Condensation, Precipitation, Respiration

• L: Write sentences and definitions of each word.

•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).

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.

Vocabulary Journal

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).

Key Question for CyclesWhen have you eaten a part of a dinosaur from 210 million years ago?

Objectives and StandardsObjectives• C: Explain why matter is never created or

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

and a 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).

I. Every living thing needs Water, Carbon and Nitrogen

A. Your body is about 70% water.

B. Your DNA and your food is made with Carbon

C. Your muscles are made with Nitrogen

















II. Matter is cycled in nature—it is never created or destroyed.

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.

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)

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)

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.
