plants can photosynthesise... produce
glucose for respiration and therefore
survive
organisms live of producers. therefore without CO2
--> no producers --> no organisms survive
use the glucose to produce yield
like berries and fruits
Global Warming
CO2 increased, mid 1800 288part per
million/ 380ppm 2000.
CO2 released from destroyed carbon sinks..
increase crop yield , photo.. more , CO2 not
limiting factor
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
number of species vary. WARMER +

MOSQUITO POP. TOPICAL
INSECTS ONLY THRIVE IN
SPECIFIC TEM RANGES, TOO HOT
--> UNABE TO REPRODUCE

distribution of wild animal and plants: SPECIES WARMER TEMP
SPREAD FURTHER AS CONDITION THEY THRIVE IN EXIST OVER

change number of species BOARFISH INCREASING IN
NUMBER IN PARTS OF ATLANTIC OCEAN WHERE SEAS
TEM IS RISING
POLAR BEARS NEED FROZEN SEA, GLOBAL WARMING --> MELT. DECREASE IN
HABITATS,......
Haemoglobin
BOHR EFFECT: Haemoglobin more readily gives up O2 at higher partial pressure of CO2.
because CO2 increase pH,
changes shape of
haemoglobin
means there is a sufficent supply of O2 to respiring cells - as
they respire more, more CO2, more readily O2 given.
