The winning photographer - Greg Lecouer - has won £2,000 ($2,500) in prize money and a 10-day trip for two to the Galápagos Islands with National Geographic Expeditions.
A panel of photographers and editors from National Geographic ranked 2016's most powerful photos of natural phenomena. The competition was split into four categories - Landscapes, Action, Animal Portraits and Environmental issues.
The photos offer rare insights into the world around us, from a meteor soaring across India's city skylines to praying mantises dancing on a single vine.
