Here’s a 3 tweet run down on how the life on our amazing planet fuels itself.
Plants are essentially living solar panels that are capable of capturing this energy in a chemical form by the production of sugars.
They use this to fuel their growth.
Pretty much all terrestrial life lives by stealing these carbs directly or indirectly from plants.
In omnivorous species, like humans, they are our key energy source, fuelling all our cells.
