Document Summary

30. 1 - why study protists? malaria - from protist plasmodium it. Best studied of all protists but haven"t been able to devise effective and sustainable measures to control. Plasmodium evolved resistance to some drugs used to control growth in infected ppl. Developing a vaccine against it have failed. Primary producer - produce chemical energy from sunlight (aka diatoms) Plankton - drift in oceans and lakes like diatoms. Food chain - nutritional relationships among organisms; how chemical energy flows within ecosystems (bottom of chain = protists) Global carbon cycle - carbon atoms from co2 move to land/sea organisms and back into atmosphere. Co2 in atmosphere dissolve in water taken by primary producers converted to organic matter. When blooms happen, carbon amount that rains into sinks in form of shells and dead cells increase fertilizing ocean to promote blooms is effective way to reduce co2 concentration in atmosphere.
