Marine Biology
Nutrient availability refers to the presence and accessibility of essential nutrients in the environment, which are crucial for the growth and productivity of organisms, particularly phytoplankton in marine ecosystems. In the context of oceans, nutrient availability influences primary production by affecting the growth rates of phytoplankton, which form the base of the marine food web. Factors like light, temperature, and nutrient concentration can vary significantly in different ocean regions, impacting overall ecosystem health and productivity.
