ECOLOGISTS GO INTO ECOSYSTEMS TO OBSERVE, BUT ALSO USE REMOTE SENORS ON AIRCRAFT AND SATELLITES TO COLLECT DATA AND ANALYZE GEOGRAPHIC DATA IN LARGE DATABASE. Eg. GEOGRAPHIC INFORMATION SYSTEMS (GIS), REMOTE SENSING, GIS ORGANIES, STORES, AND ANALYZES COMPLEX DATA AN COMPLEX DATA COLLECTED. OVER BOARD GEOGRAPHIC AREAS. ECOLOGIST DEVELOP MATHEMATICAL AN OTHER MODELS TO SIMULATE THE BEHAVIOR OF ECOSYSTEMS, AND ALSO USE CONTROLLED INDOOR AND OUTDOOR CHAMBER TO STUDY ECOSYTEMS
