Resource summary

Carbon dioxide may affect organisms directly or indirectly. Describe and explain these effects.
  1. Carbon Cycle
    1. saprobiontic nutrition, decomposers, photosynthesis, respiration, combustion, deforestation etc..
    2. Photosynthesis
      1. plants can photosynthesise... produce glucose for respiration and therefore survive
        1. organisms live of producers. therefore without CO2 --> no producers --> no organisms survive
        2. use the glucose to produce yield like berries and fruits
        3. Global Warming
          1. CO2 increased, mid 1800 288part per million/ 380ppm 2000.
            1. CO2 released from destroyed carbon sinks..
              1. increase crop yield , photo.. more , CO2 not limiting factor
              2. can change the life cycle of of some insects. SOME INSECTS GO THROUGH LARVAL STAGE EARLIER AND EMERGE ADULTS SOON... EVERY INCREASE 1 CELCIUS,, SOME BUTTERFLIES 10/LESS IN LARVAE STAGE
                1. number of species vary. WARMER + WETTER SUMMERS INCREASE MOSQUITO POP. TOPICAL INSECTS ONLY THRIVE IN SPECIFIC TEM RANGES, TOO HOT --> UNABE TO REPRODUCE SUCCESSFULLY
                  1. distribution of wild animal and plants: SPECIES WARMER TEMP SPREAD FURTHER AS CONDITION THEY THRIVE IN EXIST OVER A WIDER AREA
                    1. change number of species BOARFISH INCREASING IN NUMBER IN PARTS OF ATLANTIC OCEAN WHERE SEAS TEM IS RISING
                      1. POLAR BEARS NEED FROZEN SEA, GLOBAL WARMING --> MELT. DECREASE IN HABITATS,......
                    2. Haemoglobin
                      1. BOHR EFFECT: Haemoglobin more readily gives up O2 at higher partial pressure of CO2.
                        1. because CO2 increase pH, changes shape of haemoglobin
                          1. means there is a sufficent supply of O2 to respiring cells - as they respire more, more CO2, more readily O2 given.
