2. Describe and give examples of Biotic / Abiotic Factors
Definition:
Living / once living factors in an ecosystem
Non-living / Never Living factors in an ecosystem
Example
Air / water / temperature / rocks / sunlight

3. Definition in own words
What are the levels of organization in an ecosystem from least complex to most complex? Explain definition of each.
Level
Definition in own words
Least Complex
Organism
1 single individual organism
Population
2 more organism of the same species that can reproduce
Community
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

4. 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

5. Explain the 3 Domains of Taxonomy below..
Bacteria
Contains organisms within kingdom bacteria
Prokaryotes
Can live just about any type of environment
Archaea
Contains all organisms in kingdom Archaea
Many live in harsh environments
Many live in open ocean or soil
Eukarya
Contains kingdom Protista, fungi, Animalia, plantae
Eukaryotes
Can be unicellular or multicellular

6. What are the 4 kingdoms of Domain Eukarya?
Name of Kingdom
Unicellular / Multicellular
Autotrophic / heterotrophic
Sexual / Asexual Reproduction
Picture
Protista
Both unicellular and multicellular
Autotrophs (algae)
Heterotrophs
Sexually
Asexually
Plantae
Multicellular
Autotrophs
Fungi
Unicellular
OR both
Animalia
Heterotrophic
Most sexually

7. *Not genetically diverse
Explain how sexual reproduction and asexual reproduction are alike and different.
Sexual Reproduction
Asexual Reproduction
*Takes 2 , 1 female and 1 male
*Diverse genetics
*Takes 1 to reproduce
*Not genetically diverse
Produce offspring

8. Compare / Contrast Prokaryotic cells to Eukaryotic cells
Prokaryotes
Eukaryotes
Unicellular
No nucleus
No membrane-bound organelles
Free floating DNA
Multicellular
Has a Nucleus
Has Membrane-bound organelles
DNA is inside the nucleus
Mitochondrion
Ribosomes

9. 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

10. 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

11. Explain what selective breeding is.
The practice by which humans breed specific plants or animals for desired traits

12. Use the dichotomous key to determine what each leaf is.
Magnolia
Elm
Walnut
Pine
White Oak
Spruce
Chestnut
Holly
