Flexi Says: Pollination ecology is the study of interactions among flowering plants and living pollinators, along with abiotic factors of pollination such as wind. Pollination is a critical ecological service. Without pollinators, most of Earth's terrestrial ecosystems could collapse. Agriculture is also dependent upon pollinators, without which humans would be unable to produce enough food to sustain human populations. Therefore, pollination ecologists often work closely with agriculture in developing conservation methods to preserve pollinator diversity.
