Carbon dioxide may affect organisms directly or indirectly. Describe and explain these effects.
1 Carbon Cycle
1.1 saprobiontic nutrition, decomposers, photosynthesis, respiration, combustion, deforestation etc..
2 Photosynthesis
2.1 plants can photosynthesise... produce glucose for respiration and therefore survive
2.1.1 organisms live of producers. therefore without CO2 --> no producers --> no organisms survive
2.2 use the glucose to produce yield like berries and fruits
3 Global Warming
3.1 CO2 increased, mid 1800 288part per million/ 380ppm 2000.
3.1.1 CO2 released from destroyed carbon sinks..
3.1.2 increase crop yield , photo.. more , CO2 not limiting factor
3.2 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
3.3 number of species vary. WARMER + WETTER SUMMERS INCREASE MOSQUITO POP. TOPICAL INSECTS ONLY THRIVE IN SPECIFIC TEM RANGES, TOO HOT --> UNABE TO REPRODUCE SUCCESSFULLY
3.4 distribution of wild animal and plants: SPECIES WARMER TEMP SPREAD FURTHER AS CONDITION THEY THRIVE IN EXIST OVER A WIDER AREA
3.5 change number of species BOARFISH INCREASING IN NUMBER IN PARTS OF ATLANTIC OCEAN WHERE SEAS TEM IS RISING
3.5.1 POLAR BEARS NEED FROZEN SEA, GLOBAL WARMING --> MELT. DECREASE IN HABITATS,......
4 Haemoglobin
4.1 BOHR EFFECT: Haemoglobin more readily gives up O2 at higher partial pressure of CO2.
4.1.1 because CO2 increase pH, changes shape of haemoglobin
4.1.2 means there is a sufficent supply of O2 to respiring cells - as they respire more, more CO2, more readily O2 given.
