How would an upwelling current increase the abundance of aquatic organisms?

a) upwelling brings cold, nutrient poor water to the surface, which would decrease the abundance of aquatic organisms.

b) upwelling brings cold, nutrient-rich water to the surface, which allows for an increase in aquatic organisms.

c) upwelling brings warm, nutrient-rich water to the surface, which allows for an increase in aquatic organisms.

d) upwelling brings warm, nutrient-rich water to the surface, which would decrease the abundance of aquatic organisms.

upwelling brings cold, nutrient-rich water to the surface, which allows for an increase in aquatic organisms.

Option B

Explanation:

Upwelling can be defined as an oceanographic phenomenon in which wind driven motion of dense, nutrient rich, cooler water moves towards the surface of ocean which replaces the nutrient deficient water is replaced.

The nutrient rich water helps in the increasing the growth of the aquatic organism in water.

The nutrient in water allows the plankton to make food at the surface and food is eaten by other organism which helps in a healthier population.

some of your causes might be acidic rain or natural wildfires that cause the parks to be degraded

hope this any more questions i am here plz mark brainliest

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
