A level curve of a function $f(x,y)$ is the curve of points $(x,y)$ where $f(x,y)$ is some constant value. A level curve is simply a cross section of the graph of $z=f(x,y)$ taken at a constant value, say $z=c$. A function has many level curves, as one obtains a different level curve for each value of $c$ in the range of $f(x,y)$.
