The ocean produces up to

85 percent of the Earth's

oxygen.

Tiny sea-dwelling creatures called

phytoplankton are actually the ones that

produce the vast majority of the oxygen in

our atmosphere: 50 to 85 percent to be

exact. Though they're too small to see

without a microscope, they live in the

upper layers of water and use the same

method plants do—photosynthesis—to

convert sunlight into energy, creating

oxygen in the process.

Acacia trees can warn

each other of danger.

Arcadia trees, which grow all over the

African savannah, have a unique defense

system. When animals like antelopes start to

gobble up its leaves, the tree increases

tannin production to levels that are toxic to

animals. But that's not all. The tree then

emits a cloud of ethylene gas that travels

through the air, reaching other trees so they

too can begin producing more tannins.
