Ecosystem Presentation
The Environment
The non-living parts of our
ecosystem includes the
light, water soil and rocks.
The temperature is kept at
room temperature
Living Things
The living part of our
ecosystem includes the
cabbage, pepper, roly
polys, spider, crickets,
worms and bacteria.
We have some dead
leaves in there that
used to be alive.
• A producer is an organism that
makes its own food. Green
plants use sun light and
Carbon Dioxide to make food.
Plants have chlorophyll which
is the substance that makes
them green. Plants give off
oxygen which can be used by
other animals. When another
animal eats a plant, some (not
all) of the energy from the sun
is passed on to the animal.

Producers
Producers and Consumers
• A consumer is an organism
that has to get it’s energy
by eating something else.
Some consumers eat
plants. They are called
primary consumers. Some
consumers eat other
consumers. They are called
secondary consumers.

Decomposers
Earthworms
These organisms are decomposers
In our ecosystem. When plants and
Animals die, the decomposers eat the
Dead material. Their waste provides rich
Nutrients that go into the soil to help
Plants grow.
Bacteria found in the soil
Isopods (a.k.a. pill bugs, sow bugs,
roly polys, doodle bugs

Interactions
The sun is the main source of all energy on Earth. Producers use energy from
the sun with Carbon Dioxide to make their food.
Plants give off oxygen which is used by
animals. Animals give off carbon dioxide
which is used by the plants

Dead leaves are
eaten by worms

him for a long time then all of a
sudden it grabbed one
We put 5 crickets in to start out with
but by the next day there was only
one.
The pepper plant is growing well but
the cabbage plant is starting to turn
yellow.
The pepper plant has some holes in it.
We think the crickets are eating it.
The roly polys stay mainly under the
rock
