  1. Diversity of Living Things – The Six Kingdoms (Pages 108-113) Archaebacteria 2. Eubacteria 3. Fungi 4. Protists 5. Plants 6. Animals

  2. Archaebacteria 1. Single celled 2. Lack nuclei 3. Divide in half • Found in harsh environments Methanogens, Extreme Thermophiles Eubacteria 1. Single celled 2. Lack nuclei 3. Divide in half • Very common Bacteria (soils), Cyanobacteria (blue-green algae)

  3. Bioluminescent Bacteria Vibrio • Free living bacteria • Fresh Water and Salt Water • Light organs – have special conditions to help the bacteria grow • Quorum sensing – determines when the bacterial colony will produce the proteins that cause bioluminescence • Bioluminescence is caused by a group of genes called the lux operon

  4. Nitrogen Fixing Bacteria Rhizobium • Soil bacterium • Bacteria are the only organisms that can take atmospheric nitrogen and turn it into ammonia, which plants can use • Live in symbiotic relationship with plants in nodules on the roots • Legumes – clovers, soybeans, kudzu, alfalfa • Once plants are harvested, nitrogen is released into the soil making it available to other plants

  5. Fungi • Absorb food through their body surface 2. Have cell walls 3. Most live on land Yeast, mushrooms, mold, mildew Protists 1.Most single celled 2. Have nuclei • Most live in water Paramecia, diatoms, amoebas, Euglena

  6. Fungi • Fungi are decomposers • Fungi secrete powerful enzymes to digest their food (what they are decomposing) • The resulting “waste” products are sometimes desirable (tasty) to us humans • Penicillim • Aspergillus

  7. Protists Paramecium Small crustaceans, daphnia Desmids Algae – round and filamentous Volvox Diatoms

  8. Plants 1. Many cells 2. Make their own food by photosynthesis 3. Cell walls Ferns, mosses, trees, herbs, grass Animals 1. Many cells 2. No cell walls 3. Ingest their food • Live on land and in water Corals, sponges, worms, insects, fish, reptiles, birds, mammals

  9. PlantsAutotrophs Angiosperms • Flowering plants • Largest group of plants • Seeds enclosed in ovary • Flowers Gymnosperms • Conifers, Ginkgos • “naked seeds” • Seeds develop on scales or cones

  10. Grasses • Prairies, savannas, shrub lands • Grasses, shrubs • Substantial, deep root system • Fertile soil

  11. AnimalsHeterotrophs Primary consumers • Herbivores • Prey animals • Very numerous • Insects, rodents, deer, rabbits Secondary, Tertiary, etc. Consumers • Omnivores • Carnivores • Not as numerous • Opossum, bear • Wolf, mountain lion

  12. Common Name Size Year round resident or migrant? Food

  13. EcosystemA community of organisms Biotic Living and once living parts of an ecosystem • Plants- living and dead • Animals – living and dead Abiotic Nonliving parts of an ecosystem • Air • Water • Rocks and sand • Light • Temperature

  14. BioticOrganization • Biosphere • Earth • Ecosystem • Both biotic and abiotic factors • Community • Group of various species that live in an ecosystem • Only biotic factors • Population • All the members of one species • Organism • An individual living thing

  15. CompetitionA relationship between two species in which both species attempt to uses the same limited resource Biotic Causes Invasive species Abiotic Causes Natural disasters Man made disasters

  16. Energy Pyramid

  17. Energy Flow Food Chain Food Web

  18. Invasive SpeciesA non-native species whose introduction causes damage to the local ecosystem • Non-native – a species that is introduced to an ecosystem • Examples: • Black Rat – first invasive species originally from Asia, started to spread around 1AD with the increase of shipping • Kudzu – brought to the US from Japan in 1876 for the Philadelphia Centennial Celebration • Burmese python – released pets beginning to inhabit the Florida everglades

  19. Chemicals and Pollution • DDT – insecticide used to control malaria, caused eggshell thinning in birds of prey • Oil Spills – oil effects all organisms it touches causing widespread illness and death • Air pollution – burning of fossil fuels causing a build up of CO2 in atmosphere • Acid Rain – when rain drops pick up sulfur dioxide from energy plants burning coal

  20. Habitat Destruction and Over Harvesting • Urbanization – loss of food, cover and sometimes predators • Agriculture – loss of woodlands and wetlands, replaced with less diverse crop fields, more herbicides and pesticides • Over fishing – decreased fish stock for commercial fisherman
