What is the trading fee on PancakeSwap?

Could you please clarify the trading fee structure on PancakeSwap? I'm curious to know if there's a flat rate, a percentage-based fee, or if it varies depending on factors such as trading volume or token type. Additionally, is there a way to reduce or eliminate these fees, perhaps through staking or holding a certain amount of the platform's native token? Understanding the trading fees is crucial for making informed decisions when trading on PancakeSwap.
