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…
