Ecology Review
Please follow the slides in order to complete your study guide
for the test!!!Ecology ReviewFirst, lets review the hierarchy of
ecology.The largest part is known as the BIOSPHERE. Bio= Life
Biosphere
BiomeBiomes are the second part of the ecological hierarchy.
EcosystemsAreas with specific Biotic (Living) and
Abiotic(non-living) factors.Look at the picture, name two biotic
factors and two abiotic factors.
CommunitiesA community is a group of interacting populations of
a species. For example Zebra, Lions, and Grass all interact.
PopulationsA group of the same organisms living in the same
place at the same time.
OrganismOrganism: One individual
Next, lets look at food ChainsA food web shows one path for
energy to flow through an ecosystem. Answer the questions regarding
food chains.
Food WebsA food web is a group of over lapping food chains.
Please answer the following regarding food webs.
Carrying CapacityThe number of organisms that exist safely in an
ecosystem.
Over-populationWhen a species grows beyond the limits of its
ecosystem.
Population DensityThe number of organisms per given area.
Example: The population density in Tokyo Japan is 89,000 people
per square mile.Limiting-FactorAny factor Biotic or Abiotic that
limits the population of a species.
SymbiosisA relationship involving two species that live in close
contact with each other.
CommensalismWhen one organisms benefits and the other is not
harmed nor helped.
MutualismA relationship in which both organisms benefit.
ParasitismWhen one organism is helped and the other is
harmed.
AdaptationAn adaptation is any change in an organism that
benefits its survival. Structural adaptations are changes in an
organisms body that help them survive.
Behavioral adaptations are changes in an organisms behavior that
help them survive.
Types of ConsumersProducer: Autotroph: creates its own food.
Primary Consumer: Heterotroph: Eats producers/ herbivore.
Secondary Consumer: Heterotroph: Carnivore
Tertiary Consumer: Heterotroph: CarnivoreDecomposerBrings down
organic waste in the environment.
Please review your notes and the slides.I am sure you will do
great on the exam tomorrow. Remember your test is timed, just like
we practiced. You will have 10 minutes for the multiple choice and
20 for the open response.Do not spend all your time on (Know Do
Prove). Use know do prove to jot down your ideas and organize
thoughts.Use all the vocabulary and be sure to answer all parts of
the question.Invasive SpeciesOrganisms that do not belong in an
ecosystem. They cause harm.
