The Circle of Life
Earth rise- A New Perspective
The spaceship earth really is traveling through
space carrying all the food, oxygen, water and supplies it has with it.
Nutrients, atoms and compounds are recycled over
Carbon, Oxygen, Hydrogen,
Nitrogen and Phosphorous- common
elements in all living things
The Water Cycle
The relatively small area at the
surface where life is found
Biosphere II in Arizona- The closed system
Author and naturalist
Told how everything
Oxygen, Carbon , Water
Nitrogen that dinosaurs
used are being used by us today.
You may have

nose, right there in the bridge of your nose!
A dinosaur falls into the water
and is fossilized
The land goes through geological uplift, the bones
are now at the top of the mountain.
Dinosaur bones often become unburied and exposed at the surface
Erosion brings water and deposits-- a little bit of dinosaur bones, a little bit of calcium, down from mountains and high altitudes
Rivers drain and travel through
a system--eventually emptying
into oceans. They bring the water
and deposits on the trip.
Water from the
river is often used to irrigate the wheat fields.
Wheat takes us nutrients
from the ground and
it becomes part of the wheat
plant. The little bit of dinosaur was in
the water and now
Is part of the wheat kernel.
Wheat is taken to the mill and ground into
flour, flour is sent to the bakery and made into bread. That little bit of dinosaur is now part of that loaf of bread.
Trucks bring the bread to the store. You buy the bread at the store.
You use the bread to make a sandwich
Your skeleton is constantly
being restructured. Calcium and
other minerals are taken out and
put back in bone to keep it
That little bit of
dinosaur, that little bit
of calcium has made the
trip and is now part of

You have a little bit of redwood, right there

tree in California. Although redwoods live for a long time, they die and eventually fall to the ground.
Trees fall and decompose. This process returns vital nutrients back into the environment to be used again.
Natural processes of decay return these nutrients and atoms back to the environment to be used again and again.
Rain in the redwood
particles ( a little bit of redwood tree) into the rivers. The rivers empty into the Pacific Ocean.
A little fish eats the redwood particle-- a bigger
fish eats it, a bigger fish eats it, etc-- then a
tuna eats the biggest fish.
Tuna are caught by commercial fishermen and sent to market. They are canned and sent to the grocery store.
You make and eat the tuna fish in a sandwich. It becomes part of your patella..
There are many
reasons to care
Ecology and the environment tie into the economy
and into a nations ability to feed and take care of
Like a boomerang, problems we throw
away seem to come back to us.
Like a hula hoop that goes round and round, with
no beginning and no end.In ecology, what goes
around comes around. We think we have gotten
rid or a problem,but they tend to come back
when we least expect it.
How to take
care of our
trash is a BIG

this is only ONE of
problems that need
solutions. Clean water,
clean air, energy

eventually fills up and

part of the solution-- we are part of the
New careers and new challenges.
Science is providing answers and
helping us find new solutions.
Take a deep breath!! Who do you think
last used that oxygen?
Will that oxygen atom go to your muscles
and be incorportated for your lifetime??
Did the winds bring that oxygen atom
from Africa, Asia or Europe? Was that oxygen atom you sucked into your lungs last breathed by Napoleon--was it last used by a dinosaur??
