Question

Quizplus · Accepted Answer

Algal beds and reefs are known to have the highest net primary productivity in marine ecosystems because of their high abundance of photosynthetic organisms such as algae and seagrasses. These organisms receive abundant light and nutrients that result in high rates of photosynthesis and organic matter production, which supports a diverse array of organisms. In contrast, the open ocean has comparatively low nutrient levels, which limits primary productivity, and upwelling zones, while having higher nutrient levels, still do not have as high productivity as algal beds and reefs. Boreal forests are terrestrial ecosystems and not marine or aquatic.
