Ecology and Evolution

1. Kingdoms

   • Animals
     • Don't have Cell walls. Multicellua feed and feed on other organisms
   • Plants
     • Have cell walls they use light energy to produce food by photosynthesis
   • Fungi
     • Cells have chitin walls reproduce using spores
   • Prokaryotes
     • Have cells walls but not made of cellulose. Don't have a nucleus
   • Protoctists
     • Exist as single cells or colonies of single cells.

2. Biotic

   • Living things
   • Organic matter

3. Abiotic

   • Non-Living things
   • E.g. Sunlight

4. Sub-kingdoms and how to classify and species for a lion it would be

   • Kingdom -animal
     • Phylum -vertebrate
       • Class -mammal
         • Order -carnivorus
           • Family -cat
             • Genus -big cat
               • Species -lion

5. Extremophiles

   • are organism that live in very extreme environment
   • Examples are high temp, high concentration of salt water and high pressure

6. Ecosystems

   • Ecosystem are physical environments with a particular set of conditions (abiotic factors), plus all the organisms that live in them (biotic factors

7. Adaptation, organisms are adapted to survive over many generations involves small changes between organisms which allow it to survive better. These changes can be internal or external
