shadows on Basic?

I have Unity Basic but I don’t see any shadows on ANYTHING. My question is: Am I able to enable shadows on anything? Preferably Objects/Terrain objects such as trees. If so, how would I go about doing so?

And to be more specific, I acknowledge that Unity Pro has ‘dynamic shadows’, I’m just curious as to if there are any ‘static’ shadows that I can hopefully make my landscapes look a little better than they currently do without any shadows. Thanks in advance!

Yes you can have shadows but only those baked with Lightmapping. See this: Unity - Manual: Lightmapping: Getting started

You can also use projector shadows for moving characters etc (not real shadows but blobs that can look pretty convincing). See this: Unity - Manual: Projector component
