Every place on Earth is an ecosystem,including our club site.

In today’s GEN club adventure, we will investigate food production eco-services…

…on our club site!

What do organisms need to survive?

• Air

• Water

• Food

• Shelter

Where does all the food on Earth come from?

The Sun!

Plants use the sun’s energy to

grow leaves, roots and stems.

Animals and fungi can use the plants

as their food.

The sun provides the energy to fuel food chains.

What is special about plants? How are they able to use the sun’s energy to make food for

themselves?

Inside many plant cells are special structures called chloroplasts that can use

the sun’s energy to make sugars.

Chloroplasts can use carbon dioxide and water from the air

and use the sun’s energy to fuel a chemical reaction that forms

sugar molecules.

OK, so the sun helps make plants grow, then

what?

Herbivores• Primary consumers • Eat plants, which gives them the energy they need to survive.

Carnivores

• Secondary consumers

• They eat other animals, which gives them the energy they need to survive.

Tertiary Consumers • Also carnivores

• They eat other carnivores for the energy they need to survive.

Food chains show how energy moves from one group of

organisms to another.

But nature is complicated!Energy really passes through food webs.

Food webs occur on land, in water, and even underground.

Where is my food?

What happens when the food an animal eats cannot be found for the entire year in one place?

MIGRATION!

Birds “fly south” for the winter.

Ruby-throated hummingbirds must migrate when their food dies back for the winter.

Can Madame Squirrel’s workers produce enough

food for all Earth’s creatures,

including people?

What Do You Think?

What are your favorite things to eat?

What Do You Think?What would a bear eat from a “forest restaurant”?

What would a fox or a rabbit eat?

What Do You Think?The next time you sit down to eat dinner…

imagine the food chains for the things on your dinner plate!

The Food Production Department provides food for more than 6 billion

people

...and must provide for the needs of all Earth’s creatures.

Food Department Threats: single variety farming (monocultures)

Controlling herbivores and diseases requires use of pesticides
