Science two

• Aerobic respiration


  Uses oxygen and converts it into carbon dioxide that takes place in your cells
• Anaerobic respiration


  Does not use oxygen to produce energy
• Respiration (word equation)


  Oxygen + Glucose → Carbon Dioxide + Water
• Respiration (chemical equation)


  Not provided
• Passageway of air through respiratory system


  • Nose/Mouth (Oxygen:inhale) → Trachea → Bronchi → Bronchioles → Alveoli (Diffusion) → Blood capillary (Diffusion) → Cells (Respiration) → O2 to CO2 → Blood capillary (Diffusion) → Alveoli (Gas exchange/diffusion) → Bronchioles → Bronchi → Trachea → Mouth/Nose
• Oxygen diffusion from alveoli to capillaries

  1. CO2 in the capillary will enter the alveoli as it gets carried to the lungs

  2. CO2 diffuses into the alveoli due to the concentration difference, and oxygen diffuses out

  3. Oxygen then moves from the alveoli into the capillary (where it combines with a red blood cell and gets carried around the body)
• Parts of the respiratory system

  • nose/mouth, trachea, bronchi, bronchioles, ribs, intercostal muscles, alveoli, diaphragm
• Cartilage rings on trachea


  Tissue that protects your bones. Larynx is a skeleton build of cartilage
• Ecology


  The study of interactions between living organisms and their environment
• Population


  One kind of organism that lives with a habitat and interbreeds to increase the numbers of its own kind
• Community


  Different populations of plants and animals that live together in the same habitat make up a community
• Habitat


  The natural home of living organisms, where they inhabit and reproduce
• Aerobic respiration


  Uses oxygen and converts it into carbon dioxide that takes place in your cells
• Ecosystem


  A habitat or area where different communities coexist with one another and interact
• Anaerobic respiration


  Does not use oxygen to produce energy
• Habitats


  • Savannah: Large open grasslands, warm and dry climate
  • Tundra:harsh empty landscape, low cold climate
  • Desert: endless land of sands, extreme hot and dry climate
  • Tropical Rainforest: dense plantation and massive trees, warm and wet climate
  • Polar ice: frozen land, extreme cold and freezing temperatures and low oxygen levels
  • Ocean: Large body of water consisting of saltwater
  • Forest: Dense vegetation and rich soil, moist environment, and a variety of ecosystems
• Respiration (word equation)


  Oxygen + Glucose → Carbon Dioxide + Water
• Humans as a population: Same population; born the same way, have the same organs and basic lifestyle. Only difference is environment, culture,wtc.. Same DNA
• Respiration (chemical equation)


  Not provided
• Organisms in habitats


  • Savannah - lions, giraffes, monkeys, zebras, hyenas
  • Tundra - arctic fox, reindeer, ice worms, arctic wolves
  • Desert - snakes, lizards, hawks, owls, ants, spider,meerkat
  • Tropical forest - parrots, monkey, snakes, plants, fish, spider
  • Polar ice - seal, polar bear, fox, walrus, seafood, fish
  • Ocean -
  • Forest -
• Passageway of air through respiratory system


  • Nose/Mouth (Oxygen:inhale) → Trachea → Bronchi → Bronchioles → Alveoli (Diffusion) → Blood capillary (Diffusion) → Cells (Respiration) → O2 to CO2 → Blood capillary (Diffusion) → Alveoli (Gas exchange/diffusion) → Bronchioles → Bronchi → Trachea → Mouth/Nose
• Abiotic factors


  Non living things that are influenced by physical factors
• Oxygen diffusion from alveoli to capillaries

  1. CO2 in the capillary will enter the alveoli as it gets carried to the lungs

  2. CO2 diffuses into the alveoli due to the concentration difference, and oxygen diffuses out

  3. Oxygen then moves from the alveoli into the capillary (where it combines with a red blood cell and gets carried around the body)
• Biotic factors


  Living things and their interactions with the enviroment
• Parts of the respiratory system

  • nose/mouth, trachea, bronchi, bronchioles, ribs, intercostal muscles, alveoli, diaphragm
• Abiotic/Physical Environment factors


  • Light
  • Temperature
  • Water
  • Minerals
  • acid/alkalinity
  • Air
• Cartilage rings on trachea


  Tissue that protects your bones. Larynx is a skeleton build of cartilage
• Light affects the environment
• Ecology


  The study of interactions between living organisms and their environment
• Temperature affects the environment
• Water affects the environment
• Population


  One kind of organism that lives with a habitat and interbreeds to increase the numbers of its own kind
• Minerals affect the environment
• Community


  Different populations of plants and animals that live together in the same habitat make up a community
• Acid/alkalinity affects the environment
• Habitat


  The natural home of living organisms, where they inhabit and reproduce
• Air affects the environment
• Ecosystem


  A habitat or area where different communities coexist with one another and interact
• Organisms have physical and behavioural adaptations to survive in their environment
• Organisms evolve over time to adapt to changes in their environment
