Biodiversity

• Biotic = living or once-living things
• Abiotic = not associated with or derived from living organisms.
• Sunlight is abiotic
• Rocks are abiotic
• Trees are biotic
• Genus species


  Often how the name of an organism is written in Scientific terms.
• Family


  Ranks below family but below genus
• Organisms that fall under the Eukarya domain have cells with nuclei.
• There are 6 kingdoms
• Organisms that fall under prokaryotes or archaea have cells that are like a nucleus.
• The 6 kingdoms


  Plantae, Protista, Fungi, Animalia, Bacteria, Archaea
• Phyla are categories used to group organisms based on shared characteristics.
• Order is a category used to group similar organisms within a class
• Families are categories that group similar organisms within an order
• Archaea and Bacteria - Contains prokaryotes (single-celled organisms that lack a nucleus)
• Eukarya contains eukaryotes (cells contain a nucleus and membraned organelles)
• Archaea - single cells that adapt to extreme (harsh) environments
• Bacteria - prokaryotes don’t live in harsh environments.
• Protista - single-celled, photosynthesis (e.g. algae)
• Fungi - mushrooms, molds and yeast
• Plantae - plant that produce photosynthesis.
• Animalia - animals that eat other organisms.
• Organisms are classified in a phylum or division based largely on general body plan.
• Arthropods - exterior exoskeletons (e.g. insects, crabs)
• Chordata (aka vertebrate) - Internal skeleton & Backbone (e.g. fish, amphibians, birds, mammals)
• Mollusca - muscular foot and soft body, sometimes covered in a shell (e.g. mussel, snails, clams)
• Class will share more characteristics with each other. 
• Examples of class:


  Reptiles, mammals, Amphibians, Crustaceans
• Examples of Order:


  Primates (monkeys), Chiroptera (bats), Rodentia (rats), Carniora (eats meat, dogs)
• Examples of Family:


  Canidae (dogs, wolves), Mustildae (otters and weasels), Felidae (cats, lions), Cervidae (deers, caribou)
• Genus and Species:


  Homo Sapiens = Humans

  Panthera leo = Lion

  Panthera tigri = tiger
