Happy Block Day

New spot in notebook: Ecosystem Energy Pyramid

Number 1 -5.

You’re sick Jerry! Sick, sick, sick!

Learning Target: With my team, we will explain why the ecosystem pyramid HAS to be shaped like a pyramid.

Now stay calm...Let’s hear what they said to Bill.

Definitions for the diagram

Ecosystem Energy Pyramid Diagram

Definitions:

Energy – the ability to cause change. Ecosystem – all of the living and nonliving

parts working together in a community. Examples include a pond, Silverton, and the world.

Ecosystem Energy pyramid - A graphic organizer demonstrating the flow of energy through an ecosystem.

Def: Sun – source of electromagnetic energy for earth.

How do you know it’s a chemical change and not a physical change?

SunChemical Energy

Light Travels to Earth

Light Energy

Most of the sunlight is lost….

It misses the earth entirely or

It hits a spot on the earth without a plant.

The spot warms up and that thermal energy floats up into the sky.

SunChemical Energy

Light Travels to Earth

Light Energy

Most of Light Energy goes into space or does not hit a plant. It is out there but not useful to us.

DEF: PRIMARY PRODUCERS

Plants Convert sunlight to

glucose (sugar) PHOTOSYNTHESIS All life on earth is

dependent on them.

DEF: HERBIVORES

Animals that EAT PLANTS for their energy.

Another example of an Herbivore...

HerbivoreChemical Energy in body

Thermal Energy*

Floats Off Into Space

*Animal uses energy to move (lost as friction) or to keep warm (heat goes off into space) – all of that energy is hard to use ever again – ENERGY FLOWS

CARNIVORES!

Well, they are all not dangerous.

ANIMALS that EAT OTHER ANIMALS to obtain energy.

*Animal uses energy to move (lost as friction) or to keep warm (heat goes off into space) – all of that energy is hard to use ever again – ENERGY FLOWS

Carnivores

Energy is Flowing through from level to level – most of it is lost as it floats into space.

Only 10% of usable energy flows onto the next level.

Thus, the higher on the pyramid you are…

The less efficient is your eating.

It takes a lot plants to feed the insects and rodents to feed a hawk.

Upper Carnivores

You know what I am talking about.

LIONS, TIGERS, AND BEARS.

Oh My!

Last in the chain – DEF: DECOMPOSERS

They recycle materials

THEY EAT DEAD ORGANISMS to obtain their energy.

Mushrooms Buzzards Oh My!

Ecosystem Pyramid

Consider this choice:

1) You can eat 1 pound of fruits and vegetables or

2) You can eat one pound of hamburger.

CONSIDER: It takes ten or more pounds of vegetables to make that one pound of hamburger.

Copy and Answer this question and then make a pyramid Haiku.

The ecosystem pyramid has a wide bottom and small top because _______.

HAIKU is 5 – 7 – 5. And/or a bumper

sticker describing why you can help the world if you eat less red meat.

Haiku

For a cow to live

Thousand pounds of plants must DIE

Vegetarian

Energy Floats Up

Not much left when you eat meat

Many plants must die
