understand the biology textbook independently.
Writing: Students will be able to fluently use the
language of biology to express their ideas.

Area of Focus: What does it mean to be living?

• What does it mean to be living?

• Video! Introduction to the Characteristics of Life…Maybe.– http://www.youtube.com/watch?v=juxLuo-sH6M
Life Work with a partner Write down every possible characteristic
necessary to consider something to be alive. Write down every possible characteristic
necessary to consider something to be non-living.
What is the difference between being dead and non-living?
Biodiversity Biodiversity: All of the living organisms in an ecosystem.
Affected by habitat changes.
Is it Living?
Made of 1+ cells
Grows & develops
Reproduces
Responds to
environment
Requires energy Bacteria, Archaea,
Plants, Animals, Fungi, & Protists are
ALL LIVING!
Biodiversity Biodiversity: All of the living organisms in an ecosystem.
Affected by habitat changes. Organism: Anything that has (or once had) all the characteristics of
life.
• Electrons (negative charge), Protons (positive charge), Neutrons (no charge)
Subatomic Particle
• Basic unit of matterAtom
• Atoms bonded togetherMolecule
• A large molecule made up of smaller units called monomersMacromolecule
• Parts of a cellOrganelle
• Basic unit of lifeCell
• Group of similar cellsTissue
• Group of tissues acting as a unitOrgan
• Group of organs that perform a specific taskOrgan System
• Living individualOrganism
• Group of individuals of same species in the same place & timePopulation
• All living (biotic) population in the same place & timeBiological
Community• All living (biotic) and non-living (abiotic) components in the same
place & timeEcosystem

Biodiversity: All of the living organisms in
an ecosystem. Affected by habitat
changes.
Ecology: The scientific study of the relationships of
organisms with their environments.

Biotic FactorsAND
Abiotic Factors
•All living components:
• Animals• Plants• Fungi• Protists• Bacteria• Archaea
•All non-living components:
• Sun• Air Molecules• Nutrients• Temperature• Soil• Wind• Rocks• Water• pH (how
basic/acidic)• Salinity (how much
salt)
“Life” “Not Life”
Biological Community
Ecosystem
Biodiversity Review of Organisms
Bacteria• Early life• Found almost everywhere
Archaea• Extreme conditions (salt, heat, no oxygen)
Animal• Multicellular• Digest their food
• Can move independently
Plant• Multicellular• Photosynthesis for food
• Rigid cell walls
• Chloroplasts
Fungi• Mostly multicellular
• Rigid cell walls
• Consume dead matter
Protist• Mostly unicellular
• Don’t fit in, but plant-like, animal-like, or fungi-like
Biodiversity Biodiversity: All of the living organisms in an ecosystem.
Affected by habitat changes. Habitat: Physical area where an organism lives. Biodiversity is affected by habitat changes:
Climate Fire Flood Invasive Species Population Size Human Activity
Great Biodiversity = Greater Stability & Resilience
If a disaster occurs, greater biodiversity increases the chances that at least some organisms survive.
Healthy!
Why?
Reading / Work Time Read Chapter 34
Take Cornell notes on each section. After you are done reading, answer
CONCEPT CHECKS at bottom of Sections 34.1, 34.2, 34.3, and 34.4
Do the Chapter 34 Review Questions 1-22
Come show me reading notes when you are finished.
Ch34: The BiosphereEcology
Biotic Factor
Abiotic Factor
Study of interactions among organisms and between organisms and their environments.
Living factors such as prokaryotes, protists, animals, fungi, and plants.
Nonliving physical and chemical conditions of an environment.
Etc….
Summary: There are several levels of ecological organization: Individual organisms, populations, communities, ecyosystems, and biosphere. These levels go from smallest to largest. An individual is the smallest unit and is a single living thing. A population is a group of those individuals … etc…
