Poluantii pot fi substante chimice (pesticide,petrol,gaze,metale,substante organice,etc.),factori fizici (caldura,zgomote,radiatii ionizante,etc.) sau biologici (germeni patogeni). Desi fenomenele si procesele poluarii sunt de o mare dicersitate si complexitate,se pot desprinde unele caracteristici. Ecosisteme. n ecologie, un ecosistem este o unitate de funcionare i organizare a ecosferei alctuit din biotop i biocenoz i capabil de productivitate biologic.
