Answer:
Superposition
Explanation:
The Law of superposition dictates that, in undisturbed stratigraphy, those items found deeper in the ground will be older than those found closer to the surface.
The law of superposition states that under normal circumstances, deeper layer of rocks or soil particles are older than those above them.
During World War I, 116,516 US soldiers were killed and 204,002 were wounded. If you add those two numbers together, the total number of US soldiers killed or wounded was 320,518.
You can represent that as a fraction of the current population of Chicago like this:

For simplicity's sake (since I assume the Chicago population number is an estimate), let's round the number of soldiers killed or wounded down to 300,000. That would look like this:

We can simplify that down a lot by dividing the number of soldiers and the number of Chicagoans by the least common denominator of 300,000. That would give us this fraction:

So for every 1 US soldier killed or wounded in World War I, there are 10 Chicagoans living in the city today.
Answer:
Population, community, ecosystem, and ecosphere.
Explanation:
In the pyramid, from smallest to largest width are the population, community, ecosystem, and ecosphere. Population refers to the same group or species of organism who live in a particular geographical area that can interbreed with each other. Different populations living in a particular area is known as community. An ecosystem is a community of living organisms living with the nonliving components of their environment, interacting with each other. An ecosphere is a planetary closed ecological system.
The answer is granting citizenship.
There are both federal and state taxes. Holding courts is both a state and federal power. And states can define criminal acts, as every state has their own statutes, but so can the country as a whole.
