Question

Quizplus · Accepted Answer

Aquatic primary productivity refers to the amount of organic matter produced by aquatic plants and algae through photosynthesis. Light and nutrients (such as nitrogen and phosphorus) are the two main factors limiting primary productivity in aquatic ecosystems. Without sufficient light, photosynthesis cannot occur, and without enough nutrients, growth and reproduction are limited. Predation, pressure, disease, and temperature may all have an impact on aquatic organisms, but they are not as directly linked to primary productivity as light and nutrient availability.
