Video! Introduction to the Characteristics of Life…Maybe. –

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 matter Atom Atoms bonded together Molecule A large molecule made up of smaller units called monomers Macromolecule Parts of a cell Organelle Basic unit of life Cell Group of similar cells Tissue Group of tissues acting as a unit Organ Group of organs that perform a specific task Organ System Living individual Organism Group of individuals of same species in the same place & time Population All living (biotic) population in the same place & time Biological Community All living (biotic) and non-living (abiotic) components in the same place & time Ecosystem Layer of earth where life exists Biosphere Chemistry Microbiology Physiology Ecology

Biodiversity  Levels of Ecological Organization

Biodiversity  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.

Biodiversity  Biodiversity: All of the living organisms in an ecosystem. Affected by habitat changes.  Ecosystem: (see previous) Biotic Factors AND 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 Biosphere Ecology 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…
