Hi, is is possible to connect USB C ethernet adapter to external monitor and than connect it to my MBP M1 pro so that it feeds internet and power with one usb C cable? Hope it is not too confusing. See pic attached. Thanks!

This looks like a use-case for a Satechi Aluminum Multi-Port Adapter V2 - 4K HDMI (60Hz), Gigabit Ethernet, USB-C Charging, SD/Micro Card Readers, USB 3.0 - Compatible with 2020 MacBook Pro/ Air M1 hub. They're expensive ($80) but well worth it. Another alternative would be the HyperDrive Power USB-C hub ($99). I have one of both and they get the job done.

Yes, monitors have this kind of functionality. The Dell U2722DE even has a built-in RJ-45 ethernet port that's transferred over the USB-C input from the computer. You get power, DisplayPort and Ethernet functionality by plugging in one cable. I'd look at monitors with USB-C plugs to computers and they can probably do what you want

I have a monitor with Thunderbolt in and out ports. I've used a USB Ethernet adapter in the Thunderbolt out port, though I could also plug into one of the USB-A ports. I also keep a USB keyboard, mouse, and webcam plugged into the monitor. Some monitors have a webcam and/or ethernet integrated into them.

Gigabit Ethernet only requires one fifth the bandwidth of USB 3 Gen 1. It doesn't require a Type C port.

Yes it's easy to do, but your diagram is wrong. The MacBook plugs into the monitor, not into the adaptor. All you need is a monitor with a USB hub, doesn't matter if it's normal USB or USB-C.

I have a 2015 Dell 27" monitor with 5 USB sockets on it. I have plugged into it: a webcam, an external HDD, a USB ethernet adaptor, and other bits and pieces.

From my (2015) MacBook to the monitor, I have the monitor cable, and a separate USB cable. That gives me access to everything plugged into the monitor, including the Ethernet adaptor. I also have a separate power lead for the MacBook.

The advantage of USBC is that it can carry USB & picture & power all in one, so with the right monitor the MacBook only needs a single cable connected to get power & picture & USB. Not all monitors can do this though, and it tends to be expensive, especially monitors that can deliver enough power through USBC to charge the MacBook.
