Question

Quizplus · Accepted Answer

Biomanipulation involves removing a significant number of organisms from the next higher trophic level in order to allow the struggling trophic level below to recover. This is typically done in aquatic ecosystems, such as lakes or ponds, to control the growth of algae by reducing the number of herbivorous zooplankton. By doing so, the algae population is controlled indirectly as fewer zooplankton are consuming the algae. This allows for a more balanced and healthy ecosystem overall.
