摘要：

Based on a comparative study of the different phases of upwelling and downwelling, a comprehensive model of average biological features at Cabo Frio region was established. For identical upwelling conditions, biological responses of equal range occur, allowing the establishment of some regional patterns. These patterns are represented by chlorophyll values that range from 0.5 to 6.0 mg m-3, and primary production ranging from 2 to 14 mg C m-3 h-1. During winter, in the absence of upwelling, organic detritus constitutes the main energy source maintaining the higher levels of the food web.
