While some species will be harmed by ocean acidification, algae and seagrasses may benefit from higher CO 2 conditions in the ocean, as they require CO 2 for photosynthesis just like plants on land. . 2. trophic cascade, an ecological phenomenon triggered by the addition or removal of top predators and involving reciprocal changes in the relative populations of predator and prey through a food chain, which often results in dramatic changes in ecosystem structure and nutrient cycling. /* Opt-out function */ Trophic cascades involve propagation of the effect along a vertical trophic chain consisting of three or more components connected by grazing or predation.
