Explain how a reduction in the nutrients in the upper layers of the ocean could lead to a decrease in the numbers of forage fish such as anchoveta.

it is a limiting nutrient limited by a single nutrient in the ecosystem, & the single goes very slow.

answer; the above statement/question is (false);
