Power and ground configuration in a schematic
In the schematics they are put next to each other to avoid cluttering the functional part, but on the PCB they are usually spread out as follows:


100nF are placed across the power supply of each ICs.
10µF is used for a group of ICs, often only one for the whole circuit, if it is not too big.
I've seen 10nF to decouple the analog supply, I suppose to be able to use a higher quality C0G capacitor without it getting much bigger. 


The total capacitance doesn't matter much.

As for the ground connection, there are probably two separate ground networks or planes, which need to be connected by a wire, and for technical reasons the schematic needs to contain that wire (so it is not forgotten).
