Biotic Factor
Abiotic Factor
Definition:
Living / once living factors in an ecosystem
Definition:
Non-living / Never Living factors in an ecosystem
Example
Example
Air / water / temperature / rocks / sunlight

What are the levels of organization in an ecosystem from
least complex to most complex? Explain definition of each.
Level
Least Complex
Organism
Population
Community
Definition in own words
1 single individual organism
2 more organism of the same species that can reproduce
2 or more populations of species that are biotic in a given area,
NO Abiotic
Most Complex
Ecosystem
An area where biotic and abiotic factors interact / a community
and the abiotic factors interacting in a given area
What are some reasons why scientist classify organisms?
To help scientist to understand biodiversity.
Biodiversity is the number of plants, animals, and
other organisms living in an area
Explain the 3 Domains of Taxonomy below..
Bacteria
Archaea
Eukarya
• Contains organisms within
kingdom bacteria
• Prokaryotes
• Can live just about any
type of environment
• Contains all organisms in
kingdom Archaea
• Prokaryotes
• Many live in harsh
environments
• Many live in open ocean
or soil
• Contains kingdom Protista,
fungi, Animalia, plantae
• Eukaryotes
• Can be unicellular or
multicellular
What are the 4 kingdoms of Domain Eukarya?
Name of
Kingdom
Unicellular /
Multicellular
Autotrophic /
heterotrophic
Sexual / Asexual
Reproduction
Protista
Both unicellular
and multicellular
Sexually
Asexually
Plantae
Multicellular
Autotrophs
(algae)
Heterotrophs
Autotrophs
Fungi
Unicellular
Multicellular
Heterotrophs
Sexually
Asexually
OR both
Animalia
Multicellular
Heterotrophic
Most sexually
Sexually
Asexually
Picture
Explain how sexual reproduction and asexual reproduction are
alike and different.
Sexual
Reproduction
*Takes 2 , 1 female
and 1 male
*Diverse genetics
Asexual
Reproduction
Produce
offspring
Takes 1 to
reproduce
*Not genetically
diverse
*
Compare / Contrast Prokaryotic cells to Eukaryotic cells
Prokaryotes
Unicellular
No nucleus
No membrane-bound organelles
Free floating DNA
Eukaryotes
Multicellular
Has a Nucleus
Has Membrane-bound organelles
DNA is inside the nucleus
Mitochondrion
Ribosomes
Explain what a “scientific name” is and the purpose for it.
Carolus Linnaeus simplified the naming of living things by
creating the “Scientific Name”
Scientific Name is the Genus the organism belongs to followed
by the Species it belongs to.
Genus Species
The purpose is so that scientists from all over the world who
may speak different languages to use the same name for an
organism
Explain what Natural Selection is.
The purpose by which organisms that inherit helpful traits
tend to reproduce more successfully than other organisms
do.
Survival of the Fittest
The four parts that contribute to natural selection is
Overproduction
Genetic Variation
Selection
Adaptation
Explain what selective breeding is.
The practice by which humans breed
specific plants or animals for desired
traits
Use the dichotomous key to determine what each leaf is.
Magnolia
Walnut
Spruce
Chestnut
Elm
Pine
White
Oak
