How is marine productivity limited in high­latitude and tropical oceans?

A- The availability of light limits productivity in both high­latitude and tropical oceans.

B-The availability of nutrients limits productivity in both high­latitude and tropical oceans.

C-The availability of nutrients limits productivity in high­latitude oceans, while the availability of light limits productivity in tropical oceans.

D-The availability of light limits productivity in high­latitude oceans, while the availability of nutrients limits productivity in tropical

Explanation / Answer

answer : The availability of light limits productivity in high­latitude oceans, while the availability of nutrients limits productivity in tropical

the sunlight is not constant in the higher latitudes , they recieve sun light for only 6 continuous months of an year. so sun light acts as the limiting factor for the productivity.

since the tropical oceans are highly stratified or due to the well developed thermocline , the nutrients ae not readily available for the growth of organisms
