Assembling Your Water Ecosystems
You have designed plants, and you have designed animals, but
isolated species are found only in museums and zoos. You cannot
really know the fish without the river, or the eagle without
the huge sky. Just so, your creatures cannot be really known
unless you examine the context in which they live. The songs
of their lives are all motifs in the many-voiced music of their
worlds. Let us try and put them into environments in which they
interact together.
To do this, you will be giving copies of your plant and animal
images to the other members of your exploratory team. When you
made water plants and water animals, you chose as many biomes
as you have team members (two explorers = two biomes, three explorers
= three biomes): Now we will put the biomes together.
I hope that the diagram below will help to explain what we
will do:
Each person should choose ONE of
the biomes that you have been working with.
Example:
Jenny chooses the rocky shore line environment.
Jose
chooses the surface community in the open ocean.
Mike
chooses the deep, clear tropical waters.
Now look at this chart. Jenny will work
with all rocky shore plants and animals, the ones that she made,
the ones that Jose made, and the ones that Mike made. She will
give her Open Ocean Plants and Animals to Jose, and her Tropical
Ocean plants and animals to Mike. Then each person will make
a page describing his/her biome.

Part One: Collect the
Images and Information for the Plants and Animals in Your Biome.
It might be a good idea if each member
of your group printed out the descriptions of his/her animals
and plants.
You will need copies of the image files,
too.
You will need to make an under water
scene similar to (or better than!) the one at the top of this
page. This will allow you to visualize your underwater environment
while doing amazing things with your drawing program!
Part Two: Divide the
organisms into
- Primary Producers: make their own food from chemicals and energy
- Primary Consumers: eat the primary producers: cannot make food
- Secondary Consumers: eat smaller predators
These relationships are called the food
chain. Sometimes there is another layer of predators but this
is rare. Five levels is the maximum length of food chain that
we see on earth.
In very simple or very challenging areas, there may be only two
levels.
Now describe the animals in each level
of your food chain. See the model in Rubric
7.
Part Three: Draw a Food
Pyramid or Food Chain.
Go
to the Biomes section to see examples of food pyramids.
Add a short explanation to the diagram of your pyramid.
Part Four: Draw an Energy
Pyramid.
This shows what happens to the energy
in your biome.
The basic rule is that every time you
go up a level in a food chain, only a small percentage of the
energy that is passed up becomes biomass (the bodies) at the
next level.
