What term is associated with areas of ocean that have high nutrients but low algal growth?
Dead zones
Warm pools
Cold seeps
HNLC zones
Answer
HNLC zones, short for High Nutrient Low Chlorophyll zones, refer to regions in the ocean characterized by abundant nutrients but surprisingly low phytoplankton growth. Despite the availability of essential nutrients like nitrogen and phosphorus, factors such as limited iron or silica, insufficient light penetration, or grazing pressure from organisms like zooplankton hinder algal growth in these areas.
