Why doesn't text piped into an echo get outputted?

Question

Why doesn't this command output "1"?

echo 1 | echo

I imagine it working this way:

1. echo 1 (outputs 1)
2. | echo (takes the 1 as an input, then echos it)

Isn't this what should happen?

Answer 1

echo doesn't use stdin, try using cat

echo 1 | cat

or

echo 1 | xargs echo
