Layer 2 vs Layer 3

I want to make sure I'm using the right terms:

Ethereum = Layer 1

Matic = Layer 2

Yield Farming Potatoes on Matic = Layer 3

——–

Ethereum = Layer 1

Yield Farming Potatoes on Ethereum = Layer 2

————-

Bitcion = Layer 1

Lightning Network = Layer 2

Yield Farming Potatoes on Lightning Network = Layer 3

——

Am I right?
