Belangrike rol in die handhawing vd balans tussen die omgewing en die web

Virusse beheer ekologiese prosesse soos voedingstofsirkilering, bakteriële en
algbiodiversiteit, asook algbloei
Algbloei – vinnige groei van alge
Virusse is patogene en veroorsaak baie siektes in plante en diere, plus mense
Bakterieë se rol in die omgewing
Sommige is nuttig soos bv, FOTOSINTESE BAKTERIEE, hierdie bakterieë
skakel CO2 en H2O om in suiker.
CHEMOSINTETIESE BAKTERIEE tree op as produsente.
Bakterieë is soms ook betrokke by ontbinding soos bv, HUMUS
Bakterieë is ook belangrik in herwinning van stikstof.
Stikstof vorm ‘n noodsaaklike deel van proteïene en nukleïensure in
plante en diere.
Stikstofkringloop
• Atmosferiese stikstof word deur weerlig en
stikstofbindende bakterieë in die grond in nitrate
omskep.
• Plante verwyder nitrate uit grond en diere kry stikstof
in dmv plante wat hul eet.
• Diere skei ontlasting en urine uit wat deur ander
bakterieë in nitrate omskep word.
• Fungi en saprofiteise bakterieë ontbind die proteïene
van dooie plante- en diermateriaal. Hierdie minerale
gaan terug in die grond om weer in nitrate omgesit
word.
