ECOSYSTEM
Be ready to sort Marsh animals into biotic and
abiotic categories
What is a niche?
Producers
Plants(producers)have the ability to turn light
energy into chemical energy(photosynthesis)
They are the foundation of every energy cycle!
Without them ecosystems do not exist.
Consumers:
Consumers can not do photosynthesis so
they must eat other plants and animals to
get chemical energy.
Consumers:
1. Herbivores: Plant eaters (deer, rabbit,
and ducks)
2. Carnivores: Meat eaters (fox, coyotes,
and owls)
3. Omnivores: Plant and meat eaters
(raccoon, Opossum, skunks, and painted
turtles )
3 types of relationships
1. Biotic to Biotic...predator/prey,
racoon/ducks…
2. Biotic to Abiotic...Humans drinking
water or breathing oxygen
3. Aboitic to
Aboitic...weathering,erosion,deposition
Interdependence
Animals and plants who need each other in
order to survive and reproduce…
Watch video # 2
Define and give at least 3 examples of
diferrent types of interdependence
Interspecies competition
How can red tail hawks and great horned
owls affect an ecosystem?
????????????????????
Why would an apple tree farmers place
beehives in the middle of his apple
orchard?
.Label as biotic or abiotic
1.
Water
2.
A owl
3.
A mushroom
4.
Oxygen
5.
Bacteria
2. Explain the concept of interdependence between
bees and apple trees.
3. From the notes… define:
a. niche
b. symbiosis
c. Mutualism
d. interdependence
e. Parasitism
4. How does the alligator and the bird that cleans its
teeth show mutualism?
5. How does a dog and a flea show parasitism?
6.What are the 3 types relationships that occur in an
ecosystem? (between biotic/abiotic)
7. In a Venn Diagram compare producers to consumers
Go with the flow!
ENERGY IS NEITHER CREATED OR
DESTROYED...IT SIMPLY CHANGES FORM
I understand how energy flows through an ecosystem

Study Guide:
1.What does the law of Thermodynamics state. How do producers
cause this process on our planet? How do consumers carry on this
process?
2.What happens as energy moves up the energy pyramid? Where does
it go?
3.What are the various categories of consumers? Give local examples
of each.
4.What is the niche of the decomposer group? Why are they
important?
5. Create an energy pyramid? (Your best one!)
On the Wall…
Create an energy pyramid from animals
found in the Mentor marsh
