根据原文 Professor: Larval CoT starfish eat phytoplankton in their first month of life, so more fertilizer in the ocean means more phytoplankton, which means more starfish, bad for the reefs. 前面教授提到说：“肥料排导致水富营养化，这些营养被 “phytoplankton” 也就是浮游植物吸收，然后开始疯长。CoT 海星在幼年时期吃浮游植物，浮游植物增多，意味着 CoT 海星有更多食物，数量就会增长。A 选项正确。
