Research on Earth's biodiversity has advanced science and engineering innovation.
Photosynthesis allows plants, algae and certain bacteria to turn sunlight into chemical energy. The amazing feat is achieved because sunlight can fuel a reaction between water and carbon dioxide that, in turn, produces carbohydrates (simple sugars) and oxygen. Here is the latest news on photosynthesis, including the oldest evidence of it on Earth and how blocking photosynthesis on a large scale can affect food chains.
From microbes to plants and large predators, every organism on Earth has evolved unique survival mechanisms and research has shown us how this biodiversity can help society.
A new picture has emerged of the rise of oxygen on Earth. A growing body of data suggests the earliest photosynthesis evolved 600 million years before the Great Oxidation Event.
Corals rely on the photosynthesis of algae for oxygen. To make sure algae get the light they need, coral tissue traps and redistributes sunlight.
Life on Earth expanded rapidly about three billion years ago, about the time the chemical process behind photosynthesis and respiration evolved, study says.
