Most smaller stars don't have a radiative zone. In the radiative zone, the material is hot and dense which enables thermal radiation transfers from the core outward though the Sun. This layer is size dependent therefore smaller stars might not have this zone at all.

Answer:
Upwelling
Explanation:
Upwelling is a phenomenon in oceanography in which wind causes cold water from the deep to move to the surface. When such occurs water rich in nutrient are pushed to the surface by the force of wind, such water are regarded as the world's most productive water because they aid production in phytoplankton and leads to the increase in population of grazing zooplankton on the surface water. It also helps in the movement of marine animals.
