Learning Objectives: Define the characteristics of all living things and use these characteristics to discriminate if an object is alive or not Define the major characteristics of organism domains and kingdoms and identify the types of organisms that would be included in each Describe the levels of biological organization 7 basic characteristics of all living things 1. All living things are composed of cells a. Cells are the smallest unit of life b. All cells arise from preexisting cells c. Organisms can be: i. Unicellular Ex. Bacteria Multi-cellular Ex. Plants 2. All living things contain the molecules of life a. Nucleic acids b. Proteins c. Carbohydrates d. Lipids 3. All living things are capable of reproduction a. Sexual b. Asexual 4. All living things use energy and raw materials to carry out metabolism a. Metabolism refers to all of the chemical reactions that occur within the cells of living things 5. All living things respond to their environment 6. All living things maintain homeostasis a. Homeostasis is the relatively constant and self-correcting internal environment of a living organism b. 96.8-98.7, ph of 6.8 7. Populations of living things have adaptive traits that allow them to survive, reproduce, and ultimately evolve Summary:  Made of cells  Contain molecules of life  Capable of reproducing  Use energy and raw materials  Respond to environment  Maintain homeostasis  Populations have adaptive traits to evolve What is biology?  Biology is the science that studies living things (organisms) and the abiotic (non-living) environments in which they live and interact  What does it mean for something to be “alive”? what does it mean to be an organism? What is an organism?  Living vs. non-living Biodiversity  Organisms have many things in common, yet they are also extremely diverse  Much of the earths biodiversity exists at the microbial level that can’t be seen with the naked eye Domains  To help make sense of this diversity, humans classify (group) organisms based on share characteristics  Bacteria- unicellular prokaryotic organism  Archaea- unicellular prokaryotic organism, most live in extreme environment  Eukarya- membrane-bound nucleus and internal compartments Kingdoms  Protists- protozoans, algae  Fungi- molds, mushrooms  Plants- mosses, ferns  Animals- invertebrates, vertebrates Organization of living things  Molecule – chemical components of life  Cell- smallest unit of life  Tissue- group of similar cells that perform the same function  Organ- structure with 2 or more tissues working together to perform a function  Organ systems- at least 2 organs working together to perform a function  Individual- single organism  Population- all individuals of the same species in an area  Community- all species in an ecosystem that can interact  Ecosystem- a community and its physical environment  Biosphere- the part of earth that supports life What is a virus?  A virus is a very complex protein (large molecule) that possess its own genes in the form of RNA and DNA macromolecules  A virus must infect a host cell and “hi-jack” that cells chemical machinery in order to metabolize nutrients and to reproduce itself  Viruses can evolve (change their genes and therefore their traits) very rapidly… (influenza and HIV) Learning objectives:  Describe the earth as a closed system w energy as the only input  Define and demonstrate use of the terms biosphere, ecosystem, community, population niche and habitat  Describe how energy moves through an ecosystem and construct an original food web  Differentiate between producers and consumers  Explain energy and biomass pyramids  Describe the concept of biological magnification  Explain practical concerns that result from decreasing biodiversity Extinction  99.9% of the species that have ever existed on the planet earth are extinct  Current extinction rate is estimated to be >1000X normal background levels  Mass extinction o A large number of species become extinct over a short period of time due to extraordinary and sudden environmental change  Background extinctions o These extinctions occur at lower rates during times other than mass extinction Ecology  The study of interactions between organisms and between organisms and the environment o From the Greek work “oikos” which means “home”  Energy is supplied by the sun o Enters the living world as photosynthetic organisms trap the suns energy and transform it into glucose during photosynthesis Energy Flow  Trophic Level o = feeding level  Producers o Photosynthesizers o Form the lower trophic level  Consumers o Use energy stored by producers o Form higher trophic levels  Herbivores  Latin: “herba” – small plant and “vorare” – to devour o Primary consumers  Eat plants  Insects, grazing animals etc.  Carnivores o Latin: “carne”- flesh o Secondary Consumers  Feed on herbivore  Frog, robin, etc.  Tertiary o Feed on other carnivore  Hawk, snake, fox, etc.  Omnivores o Latin: “omni” – all o Eat both plants and animals  Human bear chicken pig  Decomposers o Consumes dead organic material for energy  The major decomposers are bacteria and fungi  Release inorganic material that can be used by producers Two ways to depict feeding relationships  Food chain o Linear sequence o Simplistic  Food web o Many organisms eat at several trophic levels o More realistic 10% Rule  Energy is lost when it is transferred from one trophic level to the next o 10% of energy available at one trophic level is transferred to the next  This is why ecosystems rarely have more than 4 or 5 trophic levels  Only the energy converted to biomass is available to the next higher trophic level o Biomass= dry weight of an organism Ecological pyramid  Diagrams that compare certain proprieties in a series of related trophic levels o Pyramid energy  Depicts energy available at each trophic level o Pyramid of biomass  shows the total mass of organisms at each stage of a food chain 2 lessons for ecological pyramid 1. Non-degradable substances accumulate to higher concentrations in organisms at higher trophic levels 2. more humans could be nourished on a vegetarian diet than on a diet containing meat Biological magnifications  the tendency of non-degradable chemicals to become more concentrated in organisms in each successive trophic level
