Do any plants or animals use it? Please help. Any way that its used in nature would be great!

Thank you!
Thank you for the last answer, but I am looking more for the ways it is used in nature-like if animals or plants use it at all. Thanks though!

Because of its chemical inertness and high fusing point, platinum is valuable for laboratory apparatus, such as crucibles, tongs, funnels, combustion boats, and evaporating dishes. Small amounts of iridium are usually added to increase its hardness and durability. Platinum is also used for contact points in electrical apparatus and in instruments used for measuring high temperatures. Finely divided platinum in the form of platinum sponge or platinum black is used extensively as a catalyst in the chemical industry. A considerable amount of the platinum used in the United States goes into jewelry, in which it is often alloyed with gold. It is also used for dental fillings.

Platinum is mined all over the world; in the late 1980s the Union of Soviet Socialist Republics (USSR) and South Africa were the leading producers. Canada, with mines in Ontario, where platinum is associated with nickel ore, ranked third in world production. Other leading producers are Colombia and the United States.
