Does Polkadot get burned?

I'm curious about a concept related to Polkadot, a popular blockchain network. I've heard of the term "burning" in the cryptocurrency world, and I'm wondering if it applies to Polkadot as well. Can you explain what "burning" means in this context, and if Polkadot tokens undergo this process? Additionally, if Polkadot does indeed get burned, what are the implications of this for investors and the overall network? I'd appreciate a clear and concise explanation to help me better understand this aspect of Polkadot's operations.
