I once had a boyfriend who couldn't write unless he was wearing a necktie and a dress shirt, which I thought was really weird, because this was a long time ago, and no one I knew ever wore dress shirts, let alone neckties it was like he was a grown-up reenacter or something.
Some plants are carnivores, gaining nutrients by eating various small insects and spiders. A well known example of a carnivorous plant is the Venus Flytrap.
Alkali metals such as sodium, potassium, rubidium, caesium and francium are extremely reactive elements, just putting them in water can result in an explosion! They are carefully stored in oil to prevent this happening.
While aluminum is the most common metal found in the Earth's crust, the most common metal found on Earth is iron, mostly because it makes up such a large part of the Earth's core.
