00:00How Keystone Species Hold Ecosystems Together Through Daily Survival
00:05A honeybee lands on a flower and gathers pollen.
00:09Across forests, oceans, and grasslands, key species pollinate plants, regulate prey,
00:14and keep ecosystems functioning through daily survival behaviors.
00:18A honeybee flies between wildflowers, spreads pollen across fields,
00:23and supports crops that feed millions of people worldwide.
00:26A gray wolf hunts elk in Yellowstone, reduces overgrazing,
00:31and allows forests and riverside plants to recover naturally.
00:35A sea otter cracks sea urchins in Pacific kelp forests,
00:39prevents overgrazing, and keeps underwater ecosystems from collapsing.
00:43An African elephant pushes over trees and savannas,
00:47opens space for new growth, and shapes entire landscapes through movement.
00:51A coral polyp builds reef structures in tropical oceans,
00:55shelters fish populations, and protects coastlines from storm damage.
01:00A bat flies through farmland at night, eats thousands of insects,
01:04and reduces crop pests without chemical pesticides.
01:07From pollination to predator control,
01:10these species hold ecosystems together
01:13through actions that ripple across entire environments.
01:17Remove one, and the system starts to break.
