Document Summary
Paraphyletic group- they represent some, but not all, of the descendents of a single common ancestor. Protists are all eukaryotes that are not green plants, animals or fungi. Plasmodium are capable of parasitizing humans and causing malaria. Plasmodium spends part of its life cycle inside mosquitoes; most antimalaria campaigns have focused on controlling these insects. Harmful algal blooms: due to photosynthetic protists called dinoflagellates. Harmful at high population density because synthesize toxins to protect themselves from predation. Protists play a key role in aquatic food chains. Plankton: small organisms that live near the surface of oceans or lakes and that drift along or swim only short distances. Sugars and organic compounds produced by phytoplankton are the basis of food chains in freshwater and marine environments. Global carbon cycle: movement of carbon atoms from co2 molecules in the atmosphere to organisms in the soil or ocean, and then back to atmosphere.
