Thursday, September 19th , 2013___________________________________________

Daily Objective:By the end of today I should be able to…•Explain what ecology is•Identify the levels of organization that ecologists studyEntrance Activity:•Open your book to page 63 and read the chapter mystery.•What is mystery you will be trying to solve in this chapter?

Ecology – The scientific study of interactions among organisms and their environment.

Comes from the Greek word “oikos” meaning house.

I. Interactions and Interdependence

Nature’s “houses” come in many different sizes. Imagine yourself sitting in

your room at home. Each of the levels around you

creates a bigger and bigger house

All life exists Air (atmosphere)– Water – Land -

Biosphere – The Level that contains

the ENTIRE PLANET.

To understand relationships within the biosphere, you need to understand all the levels that life can be observed.

From Smallest →Largest◦ Species, Population,

Community, Ecosystem,

Biome, Biosphere

II. Levels of Organization

Biotic and Abiotic Factors The living and non-living factors

determine the survival and growth of an organism and the productivity of the ecosystem in which the organisms lives• Biotic (living) all living aspects of a habitat

that an organisms might interact with• Abiotic (nonliving)Temperature, precipitation,

wind, nutrient availability, soil type, sunlight

Biotic Abiotic

SELF CHECK!!

1. What is ecology?2. What does the word NESTED mean?3. Order the following:

• Population, ecosystem, biome, species, community

4. What is an ABIOTIC factor?5. What is a Biotic factor?

Review your biotic and abiotic connections from yesterday.

One way flow of energy!!Food CHAINS and WEBSArrows point to the movement of ENERGY!!!

Tuesday, September 23rd , 2014___________________________________________

Daily Objective:By the end of today I should be able to…•The movement of energy through an ecosystemEntrance Activity:•In looking at your homework from yesterday… select one word to explain and give an example of…

• Which word is it?• What is your example?

Sunlight is the main source of energy for life.

Does Main mean ALL????

What is the main

source of energy

for our Planet?

Some types of organisms rely on energy from other sources such as inorganic chemicals… Think about things at the bottom of the ocean…

PRODUCERSDef: Autotrophs – Organisms that use energy from their environment to make food.

• We refer to Autotrophs as “Producers” since they Produce all the energy that is needed by all other life!

a) Energy from the Sun

• What is the name for the process of turning light into food?

• On land, plants are the main source of photosynthesis, in the oceans it is bacteria!

b) Life w/o Light• What happens when Light doesn’t reach Life? Is there just, “no life there”?

Def: Chemosynthesis – a process where organisms use inorganic chemicals as their energy source.

Review: What are Primary producers?

II. ConsumersDef: Heterotrophs – Organisms that rely on other organisms for their food and energy supply.

• We refer to Heterotrophs as “Consumers” since they have to consume other things to live.

II. Consumers pg. 71

• What different kinds of Consumers can there be?

• Herbivores – • Carnivores – • Omnivores – • Detritivores -

Can energy or matter ever be destroyed?

III. Feeding Relationships

KC: Energy flows through an ecosystem in one direction, from the Sun or inorganic compounds, to Autotrophs, and then to Heterotrophs.

• Think about in terms of “who-eats-who”….

IN YOUR NOTEBOOK• Draw a food web that connects and shows the

transfer of energy between at least 5 different living things.

• Include pictures of each with arrows

• Write a paragraph under it explaining your connections

HOMEWORK on a separate sheet

• Write a paragraph that describes how energy moves through an ecosystem. Use the following vocab wordso Energyo Autotropho Heterotropho Decomposer

Thursday, September 25th , 2014___________________________________________

Daily Objective:By the end of today I should be able to…•Describe energy transfers throughout an ecosystemEntrance Activity:•Draw the following food chain in your notebook, then label the organisms as producers, or consumers. If they are consumers, what type of consumers are they? •Also… have out your packets from yesterday.

III. Feeding Relationships

KC: Energy flows through an ecosystem in one direction, from the Sun or inorganic compounds, to Autotrophs, and then to Heterotrophs.

• Think about in terms of “who-eats-who”….

What is energy??

Food chains• A series of steps in which

transfer of energy happens by eating and being eaten.

Food chain vs. Food Web

• Which one is more inclusive?• Which gives a more accurate picture of what is

really happening?

• They link multiple food chains together.

c) Trophic Levels Each step in a Food Chain, or Food Web, is considered a Trophic Level.

As energy is passed up each level… Only 10% of the energy is handed up to the next level!!!

ON YOUR CAPTURE SHEET…

Label each thing as autotroph or heterotroph

Label each living thing with producer or consumer

Label each consumer with the type of consumer it is.

Friday, September 26th 2014___________________________________________

Daily Objective:Same as yesterday, you do not need to rewrite it.

Entrance Activity:•In the picture below…1) Name the producers.2) Name the primary consumers3) Name the secondary consumers

YOU NEED YOUR BOOK!!!!!!!!!

With your grid…1. Lightly shade in each of the 100 boxes in

the grid labeled producer. How many units of energy are available to the producer?

2. Shade in the top row of boxes in the first-level consumer grid. How many units of energy are available to this organism?

3. Shade in only 1 box in the second-level consumer grid. How many units of energy are available to this organism?

4. Shade in one box in the inset diagram in the third-level consumer grid. How many units of energy are available to this organism?

Pyramids of energyShow the amount of energy available at each

trophic level

Pyramid of BiomassAmount of living matter available at each

Pyramid of NumbersShows the number of individuals

Monday, September 29th , 2014___________________________________________

Daily Objective:By the end of today I should be able to…•Explain the complex energy relationships within an ecosystem. Entrance Activity:•Please have out your notebook and a set of coloring utensils.•What is the difference between a pyramid of numbers and a pyramid of biomass?

Procedure 1. Go to Lowe’s and grab one bag of each of the 3 types of

fertilizer: P enriched, N enriched, and p and n enriched 2. Get 4 of the same size pots 3. Place the same amounts of the three different fertilizers in

the first 3 pots

YOU MUST HAVE YOUR TEXTBOOK TODAY!!

CHAPTER 3 TEST TOMORROW!!

If one of the nutrients are in short supply, the ecosystem will cease to produce…

In soil… when the nutrients are used up,

farmers can apply fertilizers which put back some of the nutrients (like nitrogen, phosphorus, calcium)

In aquatic ecosystems… Nutrient poor ocean: nitrogen Nutrient poor lakes and streams:

phosphorus

Limiting nutrient
